New York Yankees star Giancarlo Stanton has been placed on the 10-day injured list with a left hamstring strain, the team announced Sunday.
"He hasn't had (an MRI) yet. He'll get that in New York on Monday," Yankees manager Aaron Boone said Sunday. "We felt like it was at least going to be something that's going to keep him out for at least the next week."
In Saturday's second game of a doubleheader against the Tampa Bay Rays, Stanton walked in the fourth inning and advanced to second base after a wild pitch.
"When he moved up on the wild pitch, that's where it tightened up on him," Boone said after the 5-3 loss.
Stanton later scored in the fourth inning, but Mike Ford pinch hit for him in the sixth inning.
In 14 games this season, Stanton is batting .293 with three home runs and seven RBIs.
"Yeah it's tough, a guy that's starting out with MVP numbers, driving the ball, coming up in big situations for us. It's going to be a tough loss, however long he's out," teammate Aaron Judge said.
In a corresponding move, the team activated infielder Thairo Estrada from the Alternate Site.
