Twins' Austin Martin: Hurts hamstring again

Martin was activated Triple-A St. Paul's 7-day injured list Tuesday but reinjured his hamstring while scoring on a double-steal in his return to the lineup, Phil Miller of The Minnesota Star Tribune reports.

Martin initially suffered the injury April 10 and missed nearly a month before returning to action Tuesday. The severity of his setback isn't known, but Martin could be headed back to the IL.
