Right-handers Scott Atchison, Jenrry Mejia and Frank Francisco have all suffered setbacks from various arm injuries over the past few weeks, and all remain in limbo. Manager Terry Collins said he had no idea when any of them might be able to return to the big leagues.
"They're not shut down, but they're not throwing off a mound," Collins said. "They're not in pitching mode."
The Mets have actually improved their bullpen numbers without those pitchers, thanks in large part to the work of Greg Burke (6 2/3 scoreless innings in May), Scott Rice and Brandon Lyon (each with scoreless efforts in eight of his last nine outings) and Bobby Parnell (seven consecutive saves converted).
