Treinen (3-5) won Monday's 2-1 victory over Pittsburgh, recording two strikeouts in 1.1 innings.
Treinen entered with two outs and the bases loaded in the seventh and induced a Colin Moran groundout on just one pitch to neutralize the threat. He then stayed in for the eighth and fell in line for the win once Los Angeles took the lead in the bottom of the inning. The victory was the reliever's first since late June, and he's yet to permit a run in seven August innings.
