Mariners' Bryan Woo: Nursing hamstring injury

Woo was removed from Monday's game against the Rays due to right hamstring tightness.

Woo left his start with the team trainer after suffering what looked to be a right leg injury, and he's since been diagnosed with a hamstring issue. The team should have a better idea of whether he'll require a trip to the injured list after further evaluation, and he's set to undergo an MRI on Tuesday, per Daniel Kramer of MLB.com.
