Treinen earned a hold against Colorado on Saturday, pitching a perfect inning during which he struck out one batter.
The right-hander breezed through a scoreless frame to set up the save for closer Kenley Jansen. Treinen retired the side on only eight pitches, seven of which were strikes. He leads MLB with 22 holds on the season and has already tied his single-season career high set back in 2016 with Washington.
