The leash could be getting shorter for struggling reliever Bobby Parnell.
Parnell, who fancies himself as a future closer, might have trouble holding onto to the set-up role if he continues to falter.
“Bobby will either step up and do the job or we’ll find somebody else,’’ said pitching coach Dan Warthen, who has not put a timetable for when Parnell must turn it around.
Parnell’s problem has been command and a drop in velocity, likely attributed to a mechanical problem in his delivery.
Presumably, that somebody will be veteran Jason Isringhausen, who has 293 career saves. The Mets signed Isringhausen to add stability to an inexperienced bullpen, and the eighth inning role would best suit his abilities.
Even if Isringhausen is slotted into the eighth inning role, the Mets still have a problem in their pen with only one lefthander.
GM Sandy Alderson said it would be at least two more weeks on the disabled list for Jason Bay. The Mets had hoped Bay would return last Saturday.
Alderson said these types of injuries are hard to predict, but veteran Mets watchers know with their team it is always longer than expected.
Terry Collins said he likes the energy Daniel Murphy brings to the line-up, but wouldn’t say he is going with a platoon system at second base.
Murphy was penciled in to start last night, but the game was rained out. Tonight’s line-up hasn’t been posted.
