Milone (biceps) threw a 45-pitch bullpen session Saturday, Mike Berardino of the St. Paul Pioneer Press reports.
It's Milone's second side session since he hit the DL on Aug. 12. With Milone enduring no setbacks while throwing, he's slated to face hitters in batting practice Tuesday for the next phase of his rehab. He looks to be on track to return to the Twins later this month.
