Miami Marlins slugger Giancarlo Stanton is likely out for the rest of the season after MRI results showed a Grade 3 strain to his left groin on Sunday.
"It's a Grade 3 strain of his groin," Marlins president of baseball operations Michael Hill said to reporters Sunday. "We're going to rehab it, and best-case scenario is a six-week return. Obviously, there is still opportunity for G to be back this season's end. But obviously, it was a significant injury and we'll see how rehab goes."
Stanton, who has faced a bevy of injuries in his young career, was injured on the final play of the Marlins' 8-7 loss to the White Sox Saturday. In his attempt to turn a single into a double, Stanton was seen laying on the dirt at second base and was helped off the field.
"Obviously, you're disappointed," Marlins manager Don Mattingly said. "You lose that out of your lineup. It looks like it's going to be for pretty much the rest of the year.
"You're disappointed, but it's one of those things that you talk about as a ballclub from spring training forward."
Health has been a big concern for Stanton who is signed through the 2027 season on a 13-year, $325 million contract. The three-time All-Star has played 103 games this season and only suited up in 74 last year after a pitch to his face shortened his season. In his seven-year career, Stanton's career-high for games played is 150 for the 2011 season, his second year in the majors.
Stanton is hitting .244/.329/.496 and has slugged 25 home runs. He leads Miami in home runs, RBI (70) and slugging percentage (.496).
The Marlins (61-56) currently are tied with the Cardinals for the second NL Wild Card spot behind the Dodgers. The franchise has not been in the postseason since 2003, when they beat the Yankees in the World Series.
"It means we've got to find another way to win, simple as that," Mattingly said. "We did it early in the year. Giancarlo early in the year was not really contributing, and he wasn't swinging well, but we were able to sustain. I think that's really what we have to do."
