MIAMI — Marlins RF Giancarlo Stanton left the game against the Mets with a strained right hamstring.
Stanton hit a tapper in front of the plate in the 10th inning Monday and clutched his right hamstring just before he crossed first base trying in vain to beat the throw. He fell face-first and pounded the grass in anger.
Stanton rose slowly and limped off.
The 2012 NL slugging leader had shaken a slump, hitting his first home run Saturday and two more Sunday.
