Twins' Austin Martin: Back on IL

Martin (hamstring) was placed on the 7-day injured list at Triple-A St. Paul on Thursday, the Minnesota Star Tribune reports.

Martin was activated from 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. Martin initially suffered the injury April 10 and missed nearly a month before returning to action.
