Thielbar (hamstring) gave up a home run with four strikeouts and no walks over two innings Thursday for Triple-A St. Paul. He could be activated from the injured list this weekend, Bobby Nightengale of the Minneapolis Star Tribune reports.
Theilbar has made two appearances for St. Paul during his rehab stint and given up one run over three innings with a 5:1 K:BB. The Twins had indicated they wanted him to make two rehab appearances as he completes his recovery from a hamstring strain, so he looks ready to return.
