Pete Alonso has been placed on the 10-day IL with a right hand sprain, the Mets announced Friday.
Luis Rojas said that an MRI revealed "nothing major," but that the sprain is something that's been "bothering him."
"We went ahead and put him on the IL so he could get some treatment there and then progress into getting some swings," Rojas said. "Want to make sure nothing is bothering him, so we'll see how it goes day-to-day with the treatment, and then we'll [see] with his progressions if he'll meet us right after the 10 days of the IL stint."
Rojas surprised us on Wednesday night after their walk-off loss to the Atlanta Braves, when he revealed that Alonso was held out of the game due to a hand/wrist injury.
Even more surprising, Rojas said the team believes the injury occurred a couple weeks ago during the Mets' series in St. Louis, when Alonso got hit by a 95-mph pitch in the hand.
Alonso took his base and continued playing in that game -- and the next 11 games after that before being held out of Wednesday's game.
"Since I got hit about two weeks ago, I just haven't felt normal, I haven't felt myself," Alonso said Friday. "...With that being said, we did a lot of treatment and we got pretty much all the swelling out. I've been doing a lot of work in the training room, the training staff has been absolutely incredible helping this thing.
"But I'm at the point right now where it's like, if I want this thing to completely go away and get better, I'm going to need to give it some rest. I have to listen to my body. I've been grinding, I've been doing the best I can out there."
But in those 11 games, Alonso slashed a paltry .132/.261/.237 with seven walks, three RBI and one home run.
"It actually started there, going back to the St. Louis series when he got hit by the pitch on his right hand," Rojas said. "...We also did some tests for the next game and he was good with the contusion, because he got hit in the palm, so we believe how the hand got pushed back with the impact of the hit by pitch is what now has flurried up on him throughout time.
"...He said he started dealing with this a couple of days ago and his grinding to get in there. ...So we went this route just to make sure we get rid of this and Pete is ok, and then he can be back with us as soon as he can."
A 10-day IL stint and potential rehab play thereafter could push his potential return to the team into June, but there's also a chance he's ready for the Braves series on the 29th.
Alonso hopes this whole thing will be done "as quick as possible," but in the right way as well.
"I need to make sure my body is right. ...I have a goal in mind, but I also need to understand that if I rush it a day or two, that could take away a couple days," he said. "So I need to listen to my body and really lock in on getting better.
"But I miss playing already. I want to be in there every single day. ...If I want to win the war, I gotta get right."
