Schanuel (calf) is starting at first base and batting second in Monday's series opener against the Mariners, Jeff Fletcher of The Orange County Register reports.
Schanuel began Sunday's game in the dugout after exiting early Saturday due to left calf tightness. However, the lefty-hitting first baseman was able to pinch hit Sunday, going 2-for-2 with an RBI single in an 8-5 win over Oakland. Schanuel will face off against Mariners right-hander Bryce Miller on Monday.
