The pain signals no longer were flooding his brain. Face down in a prone position beyond first base after his right hamstring strain Monday, Giancarlo Stanton already was thinking about the recovery.

"Here we go, this month process to bring everything back," said Stanton, before the Marlins' 2-1, walk-off win over the Mets Tuesday. "If we could just erase all of April that would be lovely."

Stanton's nightmarish month culminated with what figures to be an extended stretch on the disabled list. The Marlins immediately shelved Stanton after Monday's 4-3, 15-inning win over the Mets. Stanton felt the proverbial pop in his hamstring running out a tapper in front of the plate in the 10th inning.

An MRI revealed a grade two strain. On a positive note, the problem is in the middle of the muscle and not close to connective tissue around the joints. The Marlins offered no timetable for his return, but count on him missing all of May and in all likelihood part of June.

"Oh yeah, it could always be worse," said Stanton, who will miss a trip home to Los Angeles on the next road trip. "It's kind of on me the next few days or few weeks on how fast it's going to progress…It's pretty frustrating, but then again I prepared the way I should have. It's never a good time, but this is probably one of the worse times."

Taking Stanton's place in right field for the foreseeable future is Marcell Ozuna, who the Marlins' recalled from Double-A Jacksonville. Rated the organization's fifth-best prospect according to Baseball America, Ozuna made his major league debut Tuesday night and struck out in his first at-bat. He singled to left his second time up as part of a 1-for-3 effort.
