Here is the latest news and possible return dates for Mets players...

March 24, 4:25 p.m.

Brandon Nimmo is expected to play Saturday in the team's spring training game against the St. Louis Cardinals, Buck Showalter said Friday.

Showalter added that Nimmo "felt good" after playing four innings in center field in a minor league game as he's been battling minor knee and ankle sprains.

The manager said that Nimmo will play Saturday as long as he wakes up feeling OK.

March 23. 3:40 p.m. 

Brandon Nimmo, who has been dealing with minor knee and ankle sprains, continues to make progress.

The outfielder took five at-bats in a minor league game on Thursday, with his trips to the plate including a triple that he ran out.

He did drills on the field on Thursday, including hitting, running, and fielding.

Barring a setback, Nimmo appears on track to be ready for Opening Day.

March 22, 11:17 a.m.

Edwin Diaz, who turned 29 years old on Wednesday, tweeted an update as he recovers from knee surgery.

"Regarding my health, I feel super good, positive in rehabilitation so I can return as soon as possible," the closer wrote in Spanish.

Diaz had surgery last week to repair a full tear of his right patellar tendon, and could miss the entire season.

However, while GM Billy Eppler said the typical recovery time is eight months, he noted that some players make it back in as few as six months -- though that's more of an exception than the norm.

In other injury news, Brooks Raley (dealing with a hamstring injury) threw on Wednesday, with manager Buck Showalter saying "so far so good" regarding Raley's progression.

March 22, 10:07 a.m.

Brandon Nimmo did hitting, fielding, and running during the Mets' off-day on Tuesday and is hoping to play in New York's last two spring training games this weekend, reports Anthony DiComo of MLB.com.

Per Mike Puma of The New York Post, Mets officials "liked what they saw" from Nimmo on Tuesday.

Speaking on Sunday morning, Nimmo said he "definitely" thinks he'll be ready for the start of the regular season.

The Mets open the year on March 30 against the Marlins in Miami.

"Low (grade) sprain, ankle and knee, which is honestly best-case scenario with what happened," Nimmo said on Sunday. "Pretty glad about that. Right now we’re just taking it day-by-day. I feel a lot better today than I did yesterday. Once we get all that inflammation out of there, I’ll feel a lot better with it. So, I’m not ruling anything out right now.

"In my heart of hearts, yeah, I do think [I'll be ready for Opening Day]. Obviously, we have to see how it goes, but yeah, right now I definitely think that I’ll be ready for Opening Day."

March 18, 4:10 p.m.

Mets CF Brandon Nimmo is week-to-week with low-grade sprains in his right ankle and knee after he underwent imaging Saturday on both areas while LHP Jose Quintana had successful bone graft surgery for a rib lesion Friday, GM Billy Eppler said Saturday.

"Brandon, this morning, woke up -- he had a little knee pain, also, so we ended up doing an MRI on both, his right ankle and right knee," Eppler said. "Both of those showed a low-grade sprain, so good news -- everything's structurally sound. So he's in a week-to-week situation right now. We've got some time before Opening Day, so we'll just continue to watch him, get an update on him probably about a week from now and then we'll be able to give a little bit better timetable on him. But all in all, feel good about the results that we got compared to what they could've looked like. So that's his situation.

"And then the other one, Quintana -- Quintana had successful surgery last night to perform the bone graft. They were able to kind of clear some of the area that had the lesion and pack with some healthy bone that they actually took out of his left hip and he'll be traveling tonight back to Miami. So he's in good spirits, in a good spot. Like I said originally, it'll probably be about a week and then we'll start moving him around a little bit more. So he's more in recovery, post-surgical-recovery mode right now. So that's the updates on those two."

March 17, 8:30 p.m.

The Mets announced that Brandon Nimmo left Friday night's game against the Miami Marlins with right ankle soreness and he will undergo imaging on Saturday.

Nimmo had to be helped off the field by trainers after awkwardly sliding into second base in the bottom of the fourth inning.

March 17, 7:53 p.m.

Brandon Nimmo needed help from trainers and limped off the field in the fourth inning on Friday night after an awkward slide into second base.

Nimmo was down on the ground in pain after the slide and appeared to grab his right knee.

Manager Buck Showalter and team trainers then rushed out to check on Nimmo and help him off the field.

March 16, 8:00 p.m.

The Mets announced on Thursday night that Edwin Diaz underwent a successful repair of the patellar tendon in his right knee earlier in the afternoon.

The All-Star closer is expected to begin a formal rehab program in about a week, though he likely will miss the whole 2023 season.

Diaz suffered the injury in the midst of team Puerto Rico’s celebration after he closed down a 5-2 win over the Dominican Republic on Wednesday night in the WBC.

He went for additional testing on Thursday, and that confirmed the worst. The Mets will now be without their shutdown reliever for the foreseeable future.

Diaz posted to Instagram following his surgery and thanked everyone for their support, adding that "the operation was successful."

"Puerto Rico, I'm good!!" Diaz wrote. "My family and I are beyond grateful with all the support we have received from you though your messages and prayers. The operation was successful thank God and we hope the recovery will be the same. Keep supporting our Team Rubio, don't leave!! Grateful and blessed for the love shown to me I will never forget it PR thank you!"

March 15, 11:05 p.m.

Mets reliever Edwin Diaz suffered a knee injury after Puerto Rico's win over the Dominican Republic on Wednesday night.

The injury came after the final out that sent Puerto Rico into the WBC quarterfinals while the team was celebrating. Diaz was carried off the field by coaches and teammates.

According to SNY's Andy Martino, the Mets are aware of the situation and are "on top of the process." Diaz is currently getting an X-ray, but it's unclear when a diagnosis will be shared.

After the game, Puerto Rico manager Yadier Molina had no update for Diaz.

“I think it was the right knee," Molina said. "He’s being treated here at the ballpark, but I don't know [the diagnosis].”

The Mets put out the following statement regarding Diaz's injury.

"Edwin Diaz injured his right knee after tonight's WBC game. He will undergo imaging tomorrow and we will update when appropriate."

March 15, 2:06 p.m.

Right-handed reliever Sam Coonrod, who was a candidate for one of the final spots in the bullpen, has been diagnosed with a high-grade late strain.

Coonrod felt discomfort following his outing on Tuesday, and underwent imaging that revealed the injury.

He had been having a terrific spring, firing five scoreless innings while allowing two hits, walking one, and striking out seven.

With Coonrod no longer an option for the Opening Day roster, it could open the door for other relievers including Stephen Nogosek and Jimmy Yacabonis.

March 15, 11:35 a.m.

Buck Showalter told reporters on Wednesday that Kodai Senga is expected to get the start on Thursday against the Washington Nationals.

Senga was scratched from his scheduled start last Saturday due to tendinitis in his right index finger, but he threw a bullpen session on Tuesday.

Senga also spoke on Wednesday, saying that as long as Showalter said he's good to go, then he will indeed be ready to take the mound.

March 14, 3:30 p.m.

Jose Quintana will undergo bone graft surgery due to a rib fracture and will be out until at least July 1, GM Billy Eppler told reporters.

Per Eppler, when looking at the initial scan that showed a stress fracture on Quintana’s fifth rib, team doctors found a lesion on his rib. That discovery prompted a biopsy which Eppler said was part of the reason for the delay in Quintana’s status report.

The lesion was tested and came back as benign which meant Quintana could either opt for the conservative care route or the surgical route with a higher probability that the bone heals. Quintana chose surgery which means he will be out for, at least, the next three and a half months.

“It will go past July 1,” Eppler said. “That’s something that we do know. Where it lands after that I think we would just be best served to kind of have periodic updates as the spring goes on.”

Eppler added about Quintana's absence: “A lot will depend how soon Jose can do physical activity, how much down time does he need after this procedure.”

March 14, 11:10 a.m.

Buck Showalter told reporters that outfielder Starling Marte will return to the lineup on Tuesday when the Mets host the Washington Nationals at Clover Park.

Marte took a pitch off his batting helmet on Sunday versus Tampa Bay, but he tested negative for a concussion and is good to return to game action. Marte is starting in right field and batting second.

Meanwhile, GM Billy Eppler told reporters that lefty reliever Brooks Raley will continue throwing but is considered "week-to-week." Eppler said that everything is positive with Raley, but he won't appear in a spring training game for at least a week as the team continues to put him through testing.

March 14, 10:45 a.m.

After throwing on flat ground on Monday, Kodai Senga took another step forward on Tuesday, throwing a bullpen session under the watchful eye of pitching coach Jeremy Hefner.

Senga also did some long-tossing before throwing off the mound.

The right-hander was scratched from his Saturday start due to tendinitis in his right index finger.

Manager Buck Showalter previously described Senga being scratched as precautionary, while Senga himself has said that he has no concerns about being ready for the start of the regular season.

March 13, 6:08 p.m.

RHP Bryce Montes de Oca has been diagnosed with a stress reaction in his elbow and will not throw for a couple of weeks, according to MLB.com's Anthony DiComo.

Luckily, Montes de Oca's MRI on Monday showed no ligament damage in his elbow. The hard throwing right-hander was pulled by trainers during Sunday's spring training game after walking three straight batters in the ninth inning.

Over three spring training appearances, Montes de Oca has allowed three runs on zero hits with five walks and four strikeouts over 2.1 innings. He owns a 2.14 WHIP and has impressed with his velocity.

March 13, 2:20 p.m.

The Mets are still gathering information as they determine the timeline for Jose Quintana, reports SNY's Andy Martino.

Per Martino, the team will know within a few days how long to shut him down, with one option being a shutdown of three months.

If Quintana is shut down from throwing for three months, it would seem that the best-case scenario for his return would be the end of July or perhaps beginning of August.

Quintana is dealing with a rib injury.

March 13, 12:18 p.m.

Manager Buck Showalter shared some positive news on Monday, saying that Starling Marte "seems to be fine" after the veteran was hit by a pitch in the helmet in Sunday's spring training game.

Marte left the game against the Tampa Bay Rays and walked off on his own. Luckily, the initial evaluations for a concussion were negative.

March 13, 10:37 a.m.

Kodai Senga, who was scratched from his scheduled start on Saturday due to tendinitis in his right index finger, threw on flat ground on Monday at spring training.

After completing his throwing session on Monday, Senga walked off the field smiling, accompanied by pitching coach Jeremy Hefner.

Senga explained on Sunday that he had no concern about being ready for the start of the season.

Manager Buck Showalter noted that Senga being scratched was precautionary, and said Monday would be a "big day" for the right-hander.

March 12, 5:05 p.m.

Starling Marte left Sunday's game against the Tampa Bay Rays after being hit in the helmet by a pitch, and his initial evaluation was negative for a concussion, the team announced.

Marte will be reevaluated on Monday, as manager Buck Showalter said he is hopeful that Marte "may have gotten lucky" and he was "pretty coherent, talking clearly."

Additionally, Bryce Montes de Oca will undergo imaging on his right forearm on Monday after he was removed by team trainers during his outing in Sunday's game. Showalter called it a "forearm strain" for the right-hander. Montes de Oca walked three straight before being pulled.

March 12, 11:50 a.m.

Kodai Senga (tendinitis in right index finger) spoke to reporters on Sunday in the clubhouse before the team's spring training game, and said that he expects to be able to make his first start of the regular season.

"For sure, I do think I will. Because I can throw right now, I could make the season right now," Senga said through a translator.

The right-hander was scratched from his scheduled start Saturday after imaging of his right index finger showed tendinitis at the base of the finger and is considered day-to-day. He was also asked if the different sized baseballs in the MLB played a factor in his minor injury, saying it has affected his grip slightly.

"There's been something that's been lingering for a little while now, so it's not like I suddenly feel bad or it's gotten worse or anything. Not any different, same," Senga said through a translator.

He added: "Yeah the big league balls over here obviously are known to be a little more slippery, don't have the tack and I think subconsciously I may have been gripping it a little bit tighter. Also the grips of my pitches have been a little different since the prior year, so I think that plays a part as well."

Senga went on to say that he'll be working with the training staff on a lot of different types of treatment, and made it clear that he only was scratched because it was a spring training game. Manager Buck Showalter added that he hopes Senga will be able to make his next start and they'll see how the treatments are going for him on Monday.

"See how it is from day-to-day, it shouldn't be very long, I hope," Showalter said. "It's just precautionary, but we know how that goes sometimes, when initially it's precautionary and then you just don't know where it ends up. I think in the near future when he takes a work day, then we can map out when he goes back in. I know where his next turn was scheduled, I'm hoping that he makes that, we'll see.

"I think tomorrow is a big day, seeing how everything, some of the treatments are doing with him, bring it around."

March 11, 8:27 p.m.

The Mets announced that Kodai Senga's imaging of his right index finger showed tendinitis at the base of the finger. He is considered day-to-day after getting scratched from his scheduled start on Saturday earlier in the day.

March 11, 6:25 p.m.

Buck Showalter updated the status of two of his pitchers in Kodai Senga and Brooks Raley before the team's game against the Washington Nationals on Saturday.

For Senga, who was scheduled to start against the Nats, Showalter said he got some imaging done on his right index finger after experiencing discomfort to make sure that the team “got arms around it.”

Had it been the regular season, the manager said Senga probably would’ve still pitched and that the team is playing it safe.

As for Raley, Showalter said that the left-hander, who is currently with Team USA in Arizona, will be back with the Mets on Tuesday and that if everything goes according to plan he should still be able to make the start of the season.

However, Showalter did mention “there’s not that buffer now” and that Raley can’t have any setbacks so the team will be careful with his injury.

March 11, 3:20 p.m.

The Mets announced Kodai Senga will not start Saturday against the Washington Nationals due to discomfort at the base of his right index finger.

The team announced Senga will undergo imaging and right-hander John Curtiss will get the start. This would have been his second appearance of the spring.

Senga made his spring training debut on Mar. 5 against the St. Louis Cardinals. He threw two innings and allowed one run on one hit with two strikeouts and two walks throwing 42 pitches (24 strikes).

March 11, 10:55 a.m.

The Mets announced Saturday that left-handed reliever Brooks Raley was removed from the Team USA roster for the World Baseball Classic after experiencing tightness in his left hamstring.

Raley underwent imaging Friday and the images showed a "low grade hamstring strain," the club said.

The 34-year-old will return to Port St. Lucie. There was no update on a timeline for a return at this time.

March 11, 9:40 a.m.

Mets' reliever Brooks Raley has been removed from the Team USA roster due to an injury, USA Baseball indicated in an announcement Saturday.

The announcement only said that Los Angeles Angels left-hander Aaron Loup was an injury replacement, and did not give any indication of the injury to the Mets lefty.

The Athletic's Ken Rosenthal confirmed a report from Friday night that Raley was the off the roster, but said there was no word on his injury. Raley was removed for what one source told MLB.com's Antony Dicomo "precautionary" reasons.

Raley, 34, joined the Mets in an offseason trade with the Tampa Bay rays in exchange for pitching prospect Keyshawn Askew. Last season with Tampa, Raley pitched to a 2.68 ERA (2.74 FIP) in 53.2 innings over 60 appearances. He recorded 61 strikeouts and 15 walks with a 0.969 WHIP.

March 10, 8:52 p.m.

Buck Showalter told reporters after Friday's 7-5 loss to the Cardinals that the Mets are expecting outfielder Brandon Nimmo to make his spring training debut on Sunday.

Earlier this week, Showalter said he was hoping Nimmo would play this weekend and he got his wish.

Nimmo's arrival comes two days after fellow outfielder Starling Marte made his spring debut on Friday. Marte went 2-for-2 with a home run and double in his return. Nimmo will make his debut against the Tampa Bay Rays on Sunday at 1:10 p.m.

March 8, 3:56 p.m.

Buck Showalter told reporters before the club's game against Team Nicaragua on Wednesday that outfielder Starling Marte is on schedule to play for the first time this spring on Friday. Fellow outfielder Brandon Nimmo will "hopefully" start playing this weekend, per Showalter.

On Marte: "He's done everything we could possibly put him through. He's been wanting to play for a couple of days now."

Showalter also mentioned that Marte probably won't play back-to-back games right out of the gate.

"I think we've taken every possible precaution that you can take, almost to a fault," Showalter said.

Meanwhile, Danny Mendick, who signed a one-year deal this offseason, will start in Wednesday's game. The utility player hasn't played since June 2022 after tearing his ACL while with the Chicago White Sox.

March 7, 1:18 p.m.

Darin Ruf made his first appearance of spring training on Tuesday when the Mets faced the Houston Astros.

It’s been a bit of a slow start in camp for the 36-year-old.

While ramping up his activities, Ruf experienced soreness in his right wrist and had to receive a cortisone shot.

With Pete Alonso away from the team at the WBC, Ruf should have plenty of opportunity to make his case for the Opening Day roster.

March 6, 5:28 p.m.

Jose Quintana underwent imaging on Monday that revealed a small stress fracture on his fifth rib on his left side, the Mets announced.

The lefty will travel back to New York to undergo further imaging, the team said. There is no current timeline for his expected return.

Quintana pitched one inning on Sunday, but exited with what the team termed left side tightness. He then withdrew from the World Baseball Classic on Monday with what he called an issue on the left side of his back.

March 6, 8:10 a.m.

Jose Quintana posted on Instagram that he has withdrawn from the World Baseball Classic due to what he called an issue on the left side of his back.

Quintana, who had been set to play for Team Colombia, added that he is focused on trying to be ready for the start of the regular season.

The left-hander exited Sunday's game with what the team termed left side tightness, and was expected to get imaging done on Monday.

Manager Buck Showalter said that "it's a little too early to know the severity" of the injury.

Quintana struck out one and didn't allow a hit in his lone inning on Sunday. The 34-year-old struggled in his debut start on Feb. 28, allowing five runs on four hits in only 0.2 IP.

March 5, 12:15 p.m.

Manager Buck Showalter spoke to reporters before the team's spring training game on Sunday, and said LHP David Peterson's X-rays on his left foot were inconclusive and he went for a CT scan.

"X-rays were inconclusive, that's why we went to the next step," Showalter said.

Showalter hopes to get the results of the CT scan after Sunday's game. He added that Peterson was "sore" after getting hit by a groundball during Saturday's game against the Miami Marlins in which he tossed two scoreless innings.

March 4, 4:45 p.m.

Mets LHP David Peterson was hit by a groundball during his appearance Saturday afternoon against the Miami Marlins. The groundball kicked off of Peterson's foot, but the 27-year-old fielded it and threw over to first for the out.

In his appearance, Peterson pitched two scoreless innings giving up two walks and striking out one.

After the game, Buck Showalter revealed that Peterson returned to Port St. Lucie to receive an X-ray on his foot. Showalter said he was a little sore so they want to get it checked out. It's on the outside part of his left foot.

March 4, 12:30 p.m.

Mets outfielders Brandon Nimmo and Starling Marte appear to be drawing closer to making their spring debuts.

Marte has been progressing well as he works his way back from offseason surgery. He’s been taking live-AB’s at camp in Port St. Lucie and is reportedly expected to make his way into the starting nine for one of the games on Friday, March 10.

This certainly bodes well for his chances of being ready for Opening Day.

Nimmo, who is healthy but taking things slow, is also expected to return at some point next week. The exact date is still to be determined, but the Mets’ leadoff hitter appears ready to roll.

March 2, 3:56 p.m.

After the Mets' 6-2 loss to the Atlanta Braves on Thursday, Buck Showalter fielded some questions and gave an update on Francisco Alvarez, saying he will catch the back half of New York's game against the Washington Nationals on Friday.

It will be the first time this spring that Alvarez -- who has been serving as a designated hitter --will be behind the plate.

March 1, 12:50 p.m.

Manager Buck Showalter spoke to reporters Wednesday prior to the team's spring training game and gave updates on a number of players, including Francisco Alvarez (right ankle), Darin Ruf (right wrist) and Starling Marte (core).

Showalter said that Alvarez, who has only appeared as a DH so far in spring training, is "probably going to be available to catch after tomorrow" as he works his way back to full strength after right ankle surgery.

"We're just being cautious, like we said earlier, same thing, nothing's changed," Showalter said. "We targeted where he would catch and he's right on it... Yeah with his ankle. Everything else is fine. They said it would be a good idea to wait, so we will."

The manager then updated Ruf's status as he has yet to appear in a spring training game this year while he recovers from a wrist injury.

"Finalizing the dates on a lot of guys to appear, Ruf's getting closer," Showalter said.

He added about Ruf: "Probably after the off day we'll probably see him... He's going to probably take some stuff on the back field. But actually appearing in a game, probably be after the off day, could change."

The Mets will be off next Monday and play the Houston Astros on Tuesday, March 7 at 6:05 p.m.

Showalter then noted that "Marte hit off of Tommy Hunter today," as he recovers from core muscle surgery in the offseason and is "right on schedule." The manager would not say which specific day Marte would make his spring debut, as things can change day-to-day.

"On the day that he appears, I'm gonna go, 'That's the day,'" Showalter said.

Additionally, Showatler gave an update on RHP Stephen Ridings, who the team claimed off waivers from the Yankees in November. Ridings missed all of the 2022 season due to various injuries, including a lat injury while rehabbing in the minors in September. Showalter said that Ridings has "big stuff" and the team is working on the "same things that the Yankees tried to unlock."

"Ridings is doing well," Showalter said. "That's the one that if somehow we could get him healthy, he's got a chance to help us."

He added: "The whole goal is for him to be a healthy pitcher at the end of spring."

Feb. 26, 4:25 p.m.

Darin Ruf (right wrist) is "getting close" to making his Mets spring training debut after he took batting practice in an indoor cage over the weekend, Buck Showalter said Sunday after New York scored a 6-3 win over the Washington Nationals at Clover Park from Port St. Lucie, Fla.

"Getting close, feeling a lot better every day," Showalter said of Ruf. "I think you'll see him in the mix, shortly."

Ruf, 36, slashed .152/.216/.197 with seven RBI in 28 regular-season games as a Met during the 2022 campaign.

Feb. 23, 10:53 a.m.

Starling Marte, who had core muscle surgery in November, had his first live batting practice session of spring training.

Marte is a bit behind most players in camp, but is seemingly on track to be ready for Opening Day.

Feb. 21, 12:59 p.m.

Designated hitter/first baseman Darin Ruf received an injection in his right wrist due to soreness he was dealing with, manager Buck Showalter told reporters.

Ruf, who was taking grounders at first base on Tuesday, will be limited over the next two or three days but should be good to go shortly, per Showalter.

The 36-year-old right-handed hitter is firmly in the mix to be the DH against left-handers, with Daniel Vogelbach expected to get the bulk of the DH at-bats against right-handers.

Tommy Pham will be another DH option against lefties.

Feb. 19, 1:35 p.m.

Mets outfielder Starling Marte underwent surgery in November to repair a core muscle, leading to questions about whether or not the 34-year-old will be ready for Opening Day.

On Sunday, Marte simply responded “yes” when asked that very question, though both he and skipper Buck Showalter explained that there will be a bit of a longer ramping up period before Marte is ready to play in game action.

“I would expect, haven’t gotten there yet on him, that he would probably be a little bit of a slow go initially,” Showalter said. “But I’m looking forward to seeing a lot of the young kids play, [Alex] Ramirez, especially."

“At first we’re just going to make sure that we’re strong enough and everything,” Marte said. “We’re going to be in the weight room a lot to make sure that we have the strength there, and then after that we’re going to take the next steps.

“It’s not really a surprise. We’ve been in constant contact all offseason. I’ve flown up to New York, they’ve evaluated me there, they re-evaluated me when I got here.”

Marte explained the surgery was performed to repair tendons on either side of his groin, an injury that he played through for “a better part” of the 2022 season.

“I was actually feeling a discomfort in my legs," he said, "and when we went to go check it out they said there was a little bit of separation, so we decided to have an operation then.”

“It was bothering me during the season for a better part of the season. It wasn’t something that I couldn’t play through, which is why I did play through it,” he added. “Thankfully, I was able to finish the season and then once the season ended, that’s when we decided to have that operation.”

Marte said he and the Mets are still working on a plan for him as it relates to spring training, but he feels “good” heading into his second season with the club.
