Pelfrey (shoulder) OK; Escobar done

5/4/2010 - MLB Mike Pelfrey New York Mets + more

Mets starter Mike Pelfrey traveled to New York after the series in Philadelphia over the weekend because of general shoulder tightness. After an MRI, he was cleared to pitch this upcoming weekend against the San Francisco Giants.

Pelfrey said his shoulder was tight before his last start, loosened during the game, then re-tightened Sunday. He plans to throw a bullpen session Tuesday in Cincinnati between starts as scheduled.

"It came back OK," Pelfrey said about the MRI. "I wouldn't make a big deal about it. It was a little sore, a little tight."

Meanwhile, matching Nolan Ryan's franchise record for March/April ERA at 0.69 wasn't enough to earn Pelfrey the National League pitcher of the month award. Colorado Rockies right-hander Ubaldo Jimenez, who went 5-0 with a 0.79 ERA and no-hit the Atlanta Braves on April 17, received the monthly honor.

Pelfrey likely will have to wait until June to make another bid. He allowed six fourth-inning runs on Saturday in Philadelphia to fall to 4-1. Pelfrey finished April with a 24-inning scoreless streak, which he upped to 27 innings before the fourth-inning flop against the Phillies.

In other news, right-hander Kelvim Escobar will have shoulder surgery Wednesday and miss the entire season.

Escobar developed a sore shoulder in March, preventing him from pitching, and it hasn't improved.
