Frank Francisco, the biggest culprit in the New York Mets' second bullpen meltdown in three games, could be losing his grip on the closer's role -- if he hasn't lost it already.

Francisco gave up three runs and did not retire a batter in Sunday's 8-4 loss to the Marlins, leading manager Terry Collins to admit afterward that he is considering a change at closer. Collins will not make any decisions until the team arrives back in New York for the start of a four-game home stand Monday.

"I've got eight options, or however many guys are down there," Collins said. "But I'm not going to address that right now. The emotions are running a little high tonight, and that's not a very good time to make a decision."

If the Mets do make a change at closer, the leading options would appear to be Jon Rauch and Bobby Parnell, both of whom boast closing experience. Parnell struggled during a tryout at closer last season, while Rauch has enjoyed some success in that position with other teams in the past.

Francisco also was ejected from Sunday's game, but only after Collins gave him the hook. The closer's beef was with home plate umpire Todd Tichenor, who called balls on several close pitches.

"I thought I was hitting my spots pretty good," Francisco said. "I wasn't getting the calls."
