Marlins outfielder Giancarlo Stanton was diagnosed with a strained right hamstring, the team announced.

Stanton left Monday's series opener against the Mets in the 10th inning after injuring his hamstring while running the bases. He immediately fell to the ground before gingerly walking off the field with the team's trainer.

Stanton went 0 for 5 with two strikeouts prior to leaving the game and there has been no timetable announced for his return.
