Philadelphia Phillies shortstop Trea Turner left Sunday's 5-4 loss to the Miami Marlins with a right hamstring strain, raising concern for one of the National League's most productive hitters as the postseason approaches.

Turner pulled up after racing to beat out a ground ball that resulted in an error in the seventh inning. He immediately motioned to the dugout and walked off under his own power before being replaced by Edmundo Sosa. The 32-year-old had homered in his previous at-bat and finished 1-for-4 on the day.

Turner will undergo an MRI on Monday.

"There's some concern there," Phillies manager Rob Thomson told reporters. "He's having a great year and he's a big part of this ball club. We'll know more tomorrow."

The three-time All-Star is batting .305 with 15 home runs, 69 RBIs and 36 stolen bases this season, while leading the NL in hits (179). He missed six weeks last year with a hamstring injury.
