Treinen (hip) made a rehab appearance for Double-A Tulsa on Saturday, retiring all three batters he faced via strikeout.
Treinen landed on the 15-day injured list Aug. 5 with left hip discomfort, but after turning in a dominant rehab appearance over the weekend, he looks on track to return to the Dodgers bullpen when first eligible Tuesday. Before he was deactivated, Treinen had turned in a 2.67 ERA, 1.09 WHIP and 38:9 K:BB over 30.1 innings for the big club while gathering five wins, nine holds and one save.
