Mariners' Jorge Polanco: Leaves game with hamstring injury

Polanco left Sunday's game against the Nationals due to right hamstring tightness.

It's unclear when Polanco sustained the injury, but Josh Rojas came in at third base in the bottom of the sixth inning while Dylan Moore shifted to second base. Polanco missed seven games in May due to a right hamstring issue, and he is set to have an MRI on Monday, per Shannon Drayer of Seattle Sports 710 AM. Before leaving Sunday's game, Polanco went 1-for-2 with an RBI on an infielder's choice in the second inning.
