Miami Marlins slugger Giancarlo Stanton expects to be sidelined for about a month because of a strained right hamstring.
Stanton underwent an MRI on Tuesday and said the diagnosis was a grade-two strain on the one-to-three scale for the injury. He was hurt trying to beat out a grounder in Monday's 15-inning victory over the New York Mets, and was put on the 15-day disabled list.
The injury occurred just as last year's NL slugging leader showed signs of emerging from a prolonged slump at the season's start. He hit his first home run Saturday, and two more homers Sunday.
Now the Marlins, already saddled with the worst record in the majors, will be without their best hitter for several weeks.
