Miami Marlins outfielder Giancarlo Stanton has been put on the 15-day disabled list with a hamstring sprain.
An MRI revealed the extent of the injury and Stanton expects to be out a few weeks in a "best-case" scenario, according to the Miami Herald. It could, in fact, be a month before the Marlins' slugger is ready to return to the lineup.
"No real timetable," Stanton told the Herald. "We don't know how long it will take. Best 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."
"There's really never a good time, but this is probably one of the worst times. If we could just erase all of April that would be lovely."
Stanton is off to a slow start this season, hitting .227 with three homers and nine RBIs in 20 games but has shown signs of breaking out lately. He had 37 homers and 86 RBIs in 123 games last season.
The Marlins also put first baseman Joe Mahoney on the 15-day DL with a strained hamstring.
YOUKILIS ON DL
New York Yankees first baseman Kevin Youkilis tried to play through back pain but gave in Tuesday and was put on the 15-day disabled list.
The Yankees announced that Youkilis had been put on the DL with a lumbar spine sprain and called up infielder Corban Joseph to take his spot on the roster.
Youkilis played Saturday against the Toronto Blue Jays after sitting out six games in a row. The former Boston Red Sox third baseman was given an epidural injection Tuesday after an MRI on Monday came back negative.
"Playing him Saturday was a mistake by everybody involved," Yankees general manager Brian Cashman told USA Today.
Youkilis was sidelined for three weeks with a similar issue last year.
Injured Los Angeles Dodgers starter Zack Greinke has started throwing again, less than three weeks after breaking his left collarbone in a brawl with the San Diego Padres.
Greinke threw from 90 feet and reported no problems, according to MLB.com.
"It's still a little achy here and there, but nothing worse than what you would expect, I think," Greinke said. "You try not to have setbacks but at the same time do what you can."
Greinke, who had surgery to stabilize the bone following the break, is expected to be back on the mound by mid-June.
