Stauffer was activated from the 15-day DL on Thursday, MLB.com's Rhett Bollinger reports. Stauffer's velocity was down a couple ticks in his last rehab appearance, so he may not be very effective out of the bullpen for the Twins. He gave up three runs on six hits over five innings (four appearances) with Triple-A Rochester. Still, they deemed that he was ready to return to his role in the middle innings and he should be available for Friday's game.
