Stammen (forearm) has progressed to throwing off a mound at 75 percent intensity, Jordan Bastian of MLB.com reports.

EDGE Analysis

The veteran reliever has been throwing 35-pitch bullpens of late, mixing in all of his pitches as he continues to build up strength in his forearm after sitting out for most of 2015 with a torn right flexor tendon. He'll likely continue to stick with bullpen sessions for the time being until he can increase his intensity and pitch count. Once he's able to ramp up to full strength, Stammen figures to begin facing live batters. Still, he appears to be on track for a return on the other side of the All-Star break.
