St. Louis Cardinals outfielder Stephen Piscotty was forced to leave Thursday's game early after injuring himself while running to first.
It appears Piscotty pulled his hamstring as he tried to beat out a grounder. Jose Martinez replaced him in the lineup and right field.
Piscotty is batting .241/.378/.380 with two home runs and 11 RBI's in 98 plate appearances this season.
