Treinen (hip) has continued to play catch and will likely be activated from the 15-day injured list when first eligible, per MLB.com.
Treinen went on the 15-day IL on Aug. 5, so the earliest he can be activated is Aug. 20. It appears likely that he will indeed return to the Dodgers' bullpen on that day, as his hip issue is not expected to be serious. Upon being activated, Treinen should slot back into a high-leverage role after posting a 2.67 ERA, 1.09 WHIP and 38:9 K:BB over 30.1 innings while recording five wins, a save and nine holds.
