PORT ST. LUCIE, Fla. -- With less than two weeks left until camp breaks, right-handed reliever Vic Black stands in the most precarious position of several Mets players nursing injuries -- a "question mark," according to general manager Sandy Alderson, who added that he's "not sure where [Black] will be on Opening Day."
Black, who has not pitched since March 9 due to right shoulder tendinitis, completed his regimen of anti-inflammatory medication and played catch off flat ground on Tuesday, but he's still not ready to return to game action. If he is not at full strength by April 6, Black will join Bobby Parnell and Josh Edgin as unavailable core bullpen members.
"I'm not worried about it," said Black, who hopes to play catch again on Wednesday, with plans of returning to game action as soon as this weekend. "As long as things progress OK and they let me go, I think I'll be ready. But they have their own methods and their own checkpoints that you have to get to. So I'll follow them and do what they ask."
Other injury updates from Mets camp:
• Second baseman Daniel Murphy remained sidelined Tuesday with a strained right hamstring, but he hopes to resume baseball activities on Wednesday. The Mets are cautiously optimistic that Murphy will be ready for Opening Day, but they won't have a clear sense of that until they see how Murphy responds to increased activity.
• Of all the injured Mets, shortstop Wilmer Flores is the closest to playing in a game. Flores hit and took ground balls on Tuesday, and he could return to Grapefruit League action as soon as Thursday.
• Starting pitcher Zack Wheeler said his goodbyes to teammates on Tuesday, with plans to undergo Tommy John surgery on Wednesday in New York City. Team orthopedist David Altchek will perform the procedure, which requires an approximate 14-month recovery.
