The Pirates have recalled left-handed pitcher Daniel Moskos from Triple-A Indianapolis and have placed right-handed pitcher Evan Meek on the 15-day disabled list (retroactive to 4/27) due to right shoulder tendinitis. Moskos, Pittsburgh’s #1 pick in the 2007 First-Year Player Draft, went 0-0 with one save and a 1.69 ERA (10.2ip/9h/3r/2er/1bb/7so) in eight games with Indy this season.

Marlins center fielder Chris Coghlan is dealing with a strained right shoulder. He missed his first game of the season on Friday night and said he had an MRI performed Thursday before the Marlins left for a seven-game road trip and there was "no structural damage." Coghlan will have to deal with the pain the rest of the season as the injury will not fully heal until he's able to rest it significantly. He didn't want to speculate over having surgery, but it's likely he will need it after the season.

Nationals third baseman Ryan Zimmerman needs surgery for a torn abdominal muscle and is expected to miss six weeks. The team says Zimmerman will have surgery Tuesday. He originally went on the 15-day disabled list April 12 with what the Nationals said at the time was a strained abdominal muscle. Zimmerman is hitting .357 with a triple, homer and four RBIs in eight games this season.

Giants third baseman Pablo Sandoval has a broken bone in his right wrist and is expected to miss four to six weeks. Sandoval probably will have surgery Tuesday. He is hitting .313 with five homers and 14 RBIs this season. Manager Bruce Bochy calls Sandoval's injury "a tough blow for us."

Brewers right-hander Zack Greinke threw 75 pitches in his rehab assignment for Triple-A Nashville on Friday and is on schedule to make his Brewers debut. His first start for Milwaukee will likely come on May 4 against Atlanta. "I know he's looking forward to this being his last one there," Brewers manager Ron Roenicke said prior to Friday's game. "To get up and down is what's important. I hope he doesn't run through his pitch count to where he's not getting up and down a lot. "But he feels good. He was a little disappointed in his offspeed stuff the last time, so hopefully he'll get that on track."

The Red Sox had two pitchers to be concerned about after Friday night’s loss to the Mariners, according to a Yahoo! Sports report. Daisuke Matsuzaka left in the fifth inning with elbow tightness after his velocity fell off from the start of the game. The injury doesn’t appear serious, but he will be checked out more on Saturday. “I think we think he’s going to be OK for his next start,” manager Terry Francona said. Bobby Jenks entered in the seventh to protect a lead and couldn’t do it. The struggling reliever gave up two runs and three hits, leaving Boston with its third loss in four games.

Orioles shortstop J.J. Hardy is still recovering from a strained left oblique. Baltimore manager Buck Showalter said Hardy took "15 dry swings; 25 off the tee with no problems, which is something he hasn't done; threw it 120 feet; and ran sprints." Hardy was expected to hit soft toss and take grounders Friday in Sarasota. No timetable is set for his return.

Yankees right-hander Phil Hughes will be examined in St. Louis on Monday by Dr. Robert William Thompson, one of the country's leading experts on thoracic outlet syndrome. The team believes Hughes is suffering from the condition, which has led to his ineffectiveness this spring and a drop in velocity. The 24-year-old showed a "slight positive" on a circulatory test this week, according to general manager Brian Cashman, suggesting that TOS might be the root of Hughes' dead-arm problems. "You're trying to come up with some clinical diagnosis based on a lot of information - some of it testing, some of it conversations with the patient about what he's feeling," Cashman said Thursday. "You try to put it all together and try to make sense of it."

Rangers reliever Darren O’Day has had surgery to repair a partial tear of the labrum in his left hip, according to an Associated Press report. The Rangers say there were no other issues found during the surgery Thursday, which was performed by Dr. Tom Byrd in Nashville, Tenn. O’Day is expected to be on crutches for about a week, though he will begin rehabilitation immediately.

The Phillies have put right-hander Joe Blanton on the 15-day disabled list with an elbow injury, according to an ESPN.com report. Vance Worley will be recalled from Triple-A Lehigh Valley to start against the Mets on Friday night.
