Giancarlo Stanton has a grade 2 hamstring strain that will keep him out of the Marlins lineup for at least a few weeks, and that's in a "best-case scenario." Stanton underwent a MRI on Tuesday, one day after pulling up lame while running the bases.

"No real timetable," Stanton said. "We don't know how long it will take. Best (case scenario) is probably two or three (weeks). The reality? I don't know really. I've got to be able to walk a normal pace first before I can predict all that."

Stanton and first baseman Joe Mahoney were placed on the 15-day disabled list immediately following the Marlins' 4-3 win over the Mets in 15 innings. Mahoney is also on the DL with a strained right hamstring. But he said a MRI showed his injury to be not quite as severe as Stanton's -- a "grade 1 plus or 2," he said. As a result, Mahoney said he is hoping to be back on the field after the 15 days are up.

Stanton, however, could be out considerably longer. Compounding Stanton's frustration: he was starting to show signs of finding his groove at the plate and was looking forward to the Marlins' once-a-season road trip to Southern Califoria, where he's from. The Marlins play in San Diego and Los Angeles next week.

"There's really never a good time, but this is probably one of the worst times," Stanton said. "It's just more of 'Here we go,' this month (-long) process to bring everything back. If we could just erase all of April that would be lovely."
