The New York Mets placed outfielder Jason Bay on the seven-day disabled list after he sustained a concussion during Friday's 7-3 home loss to the Cincinnati Reds.
Bay injured himself in the second inning by diving into the left-field wall trying to make a catch, hitting his head against it.
Bay also missed the last two months of the 2010 season with a concussion.
Scott Hairston replaced Bay in the outfield on Friday and will see increased playing time in Bay's absence.
"It's really hard to watch, especially him just coming back from injury," Hairston told MLB.com. "He's a well-liked guy. We like having him around. It's very difficult to watch a player like that go through something like that."
Mets pitcher Jon Rauch tweeted that he was disappointed in the New York fans for booing him as he walked off the field, especially since it is a much more serious injury than perhaps some realize.
Bay has struggled this season, hitting .187 with four home runs and six RBI in 75 at-bats. He recently missed 21 games with a broken rib.
--Texas Rangers outfielder Josh Hamilton was released from a hospital Saturday morning, a day after checking in and receiving fluids for an intestinal virus, ESPN Dallas reported.
Hamilton missed Friday's and Saturday's games against the Houston Astros and will miss Sunday's contest as well. He plans to come to the ballpark on Sunday to work out.
He is scheduled to play next on Monday night at San Diego.
The Rangers believe Hamilton probably got the virus from his wife and children, who have also had viruses recently. They do not think the virus is related to stomach problems players on the team have had in the past several weeks.
The Rangers called up outfielder Leonys Martin from Class AAA Round Rock Friday to take Hamilton's place.
Hamilton is a threat to win the Triple Crown as he is batting .330 while leading the American League with 22 homers and 62 RBI in 60 games this season.
--The Boston Red Sox placed right-hander Josh Beckett on the 15-day disabled list with an inflamed right shoulder, MLB.com reported Saturday.
The club will call up right-hander Clayton Mortensen from Class AAA Pawtucket to take Beckett's spot on the roster.
Beckett did not show signs of an injury in his start on Monday. He allowed four runs in the first two innings against the Miami Marlins but did not surrender a hit over his final five innings.
Left-hander Franklin Morales will start in place of Beckett on Sunday.
Beckett is 4-7 with a 4.14 ERA this season.
--The Toronto Blue Jays placed right-hander Drew Hutchison on the 15-day disabled list with a right elbow sprain, the club announced Saturday.
Hutchison is the Blue Jays' third starter to hit the DL this week. Brandon Morrow (Monday) and Kyle Drabek (Wednesday) have also been shelved.
Right-hander Robert Coello was recalled from Class AAA Las Vegas to replace Hutchison on the roster.
Hutchison, a 21-year-old rookie, is 5-3 record with a 4.60 ERA in 11 starts this season. He left Friday's game in the first inning after throwing just nine pitches.
Coello is 4-1 with a 3.00 ERA for Las Vegas this season.
--St. Louis Cardinals outfielder Carlos Beltran stole his 300th career base on Friday night to become the first switch-hitter in major league history to reach 300 home runs and 300 steals.
The Cardinals ended up losing to the visiting Kansas City Royals 3-2.
Beltran is only the eighth member of the 300/300 Club, joining Barry Bonds, Bobby Bonds, Andre Dawson, Steve Finley, Willie Mays, Alex Rodriguez and Reggie Sanders.
"I just have to thank God for the opportunity of being able to play this game for a long time," Beltran told MLB.com. "All the glory is for him. I've been fortunate to be able to play this game for long, and today, it's great. It would have been great if we would have won."
Beltran went 2-for-4 in the defeat.
Second base was pulled off the Busch Stadium field after the game and given to Beltran in the Cardinals' clubhouse. Team sources told MLB.com that Beltran might send his used spikes from the game to the Baseball Hall of Fame in Cooperstown, N.Y.
Beltran began his major league career with the Royals.
"It is crazy, but at the same time, things happen for a reason," he said. "So I can say it was good to play them today, even though we lost. For me, personally, I started my career as a Royal, I spent 6 1/2 years there, so I have good memories there in Kansas City."
Beltran, 35, leads the National League with 19 home runs and has seven stolen bases this season.
--Oakland A's starting pitcher Travis Blackley picked up his first win in eight years on Friday.
Blackley went six innings as the A's topped the visiting San Diego Padres 10-2. It was Blackley's first victory since his major league debut in July 2004.
Blackley said he was "very aware" of the drought.
A's manager Bob Melvin also managed Blackley's first win when they were with the Seattle Mariners.
Melvin remembered Blackley's first victory but did not realize it had been eight years since he had lost won a game.
"It was probably under me," Melvin said. "I remember he got a win in his first game."
Ironically, Blackley said Friday night was the worst he has felt all season on the mound despite getting the victory.
--The A's recalled right-handed pitcher Tyson Ross and infielder Eric Sogard from Class AAA Sacramento and sent down right-handed pitcher Evan Scribner and infielder Adam Rosales to Sacramento, the team announced Saturday.
The A's also sent first baseman Kila Ka'aihue to Sacramento and clearing waivers.
Ross is 2-1 with a 2.45 ERA in four Class AAA starts and is 2-6 with a 6.51 ERA in nine starts with the A's.
Sogard is batting .304 with a home run and nine RBI in 18 games with the River Cats and .136 with two home runs and six RBI in 21 games with the A's.
Scribner pitched two scoreless outings with the A's.
Rosales is hitting .167 in 13 games overall with Oakland.
Ka'aihue was designated for assignment June 6 after batting .234 with four home runs and 14 RBI in 39 games.
--The Colorado Rockies stopped an eight-game skid by scoring eight runs in the top of the 10th inning to beat the host Detroit Tigers 12-4 on Friday.
It was the most runs the Rockies have ever scored in an extra inning.
Wilin Rosario started the scoring barrage when he hit a one-out, bases-loaded single that scored two runs off Detroit closer Jose Valverde.
The big bash came from Carlos Gonzalez, who hit a three-run homer, his 17th of the year.
"It was a huge win for us," starting pitcher Jeff Francis told the Denver Post. "We had lost a few games in a row and for us to come in here and keep it tight and then bust out like we did in the 10th inning, it was huge for us as a team."
The Rockies had 16 hits in all. Chris Nelson hit a two-run homer, tripled, scored three runs and had three RBI.
--The Baltimore Orioles traded minor league left-handed pitcher Cole McCurry to the Atlanta Braves for cash, MASN Sports reported Saturday.
McCurry is 0-7 with an ERA of 6.10 this year, mainly at Class AA Bowie, but he moved up to Class AAA Norfolk on June 5. He was then added to the short-season Class A Aberdeen roster June 9 but has not been active since.
Prior to this season, the 26-year-old went 38-33 with an ERA of 3.44 in his minor league career. McCurry was a 43rd round draft pick of the Orioles in 2007.
--Philadelphia Phillies catcher Carlos Ruiz missed Saturday's game against the host Toronto Blue Jays and likely Sunday, too, with an oblique strain.
The injury forced Ruiz to leave Friday's game.
"I had an oblique problem in Colorado last year -- or a couple years ago -- and I know how it feels," Ruiz told MLB.com. "I think this is more like a cramp -- you know, when you pull a hamstring. This is more like a cramp. That's what I feel. They want to make sure that I'm OK. Today, when I woke up, maybe I was a little sore. But I feel good. I'm ready to go. We'll see how it goes."
Ruiz missed 21 days in 2009 with an oblique strain.
He did take batting practice on Saturday and will likely avoid the disabled list.
Backup catcher Brian Schneider is starting for Ruiz and the team called up catcher Erik Kratz from Class AAA Lehigh Valley.
To make to room for Kratz on the 25-man roster, the Phillies sent right-handed reliever B.J. Rosenberg to Lehigh Valley.
Ruiz is batting .362 with eight homers and 35 RBI.
--Minnesota Twins catcher Joe Mauer is out day-to-day with a sore hamstring and first baseman Justin Morneau returned after missing Friday's game with a sore left forearm, MLB.com reported Saturday.
Mauer sustained the injury while running the bases in Friday's 5-3 loss to the Milwaukee Brewers. He stayed in the game, but it got worse as the game went along, Twins manager Ron Gardenhire said.
Mauer tested the hamstring before Saturday's game but decided to sit out. Gardenhire said Mauer can pinch-hit, but would need a pinch-runner.
Ryan Doumit started at catcher in place of Mauer Saturday while Josh Willingham (sore knee) is the designated hitter.
Morneau injured his forearm while swinging the bat Thursday.
--New York Yankees outfielder Nick Swisher left Saturday's game at the Washington Nationals in the sixth inning after sustaining a left quad bruise while sliding home in the top of the inning, ESPN New York reported.
Swisher was out trying to score from third on Russell Martin's grounder to Nationals pitcher Jordan Zimmermann, who threw fired home. Swisher was tagged out by catcher Jesus Flores.
Swisher got up and limped in pain before heading to the dugout. He was replaced in right field by Andruw Jones.
The severity of the injury or how much more time he will miss was not immediately known.
--The Seattle Mariners called up left-hander Oliver Perez from Triple-A Tacoma and optioned right-hander Steve Delabar to Tacoma. They also designated outfielder Chih-Hsien Chiang for assignment.
Perez, 30, was 2-2 with a 4.65 ERA in 22 relief appearances with Tacoma. His 12.19 strikeouts per nine innings led Pacific Coast relievers.
Delabar made one appearance in his most recent stint with the Mariners. He had been sent down May 30 and recalled June 13, pitching two innings against San Diego on June 14.
Chiang had split the season between Tacoma and Double-A Jackson, hitting .242 with three home runs and 25 RBI. He was part of the deal last July that sent left-hander Erik Bedard and right-hander Josh Fields to Boston.
