Dobnak has been shut down from throwing due to continued discomfort in his right middle finger, MLB.com reports. "I think we're resetting right now in a way and allowing his finger to rest," Twins manager Rocco Baldelli said.
Dobnak struggled with a finger injury (a full tear of the A4 pulley in his right middle finger) for most of last season, so it's a real concern that he's having the same issue as spring training begins. He's likely out indefinitely.
