Osuna started in right field and went 2-for-2 with an RBI in Tuesday's 5-3 loss to the Diamondbacks.
Osuna filled in for injured right fielder Adolis Garcia (quadriceps). Texas manager Bruce Bochy said Garcia will be down for a few days, per MLB.com. The lefty hitting Osuna started against a righty and could get another start Wednesday against right-hander Zac Gallen.
