Topa (knee/elbow) threw 30 pitches in a bullpen session Saturday, MLB.com reports. It was his third bullpen session in the past week.

Topa hopes to face live hitters in a few days and then try to pitch in a rehab game with Triple-A St. Paul in late September. Topa still hopes to pitch in the majors this season, but he still has several more steps to go. Topa has resided on the injured list all season, first while recovering from a torn patellar tendon in his left knee before being pulled off a rehab assignment in August due to right elbow inflammation.
