Schanuel (ankle) is starting at first base and batting fifth versus the Astros on Tuesday, Jeff Fletcher of The Orange County Register.
Schanuel sat out Monday's series opener against the Astros due to lingering left ankle soreness that stemmed from the left ankle tendinitis he returned from June 6. Trey Mancini started at first in place of Schanuel on Monday, but he's back on the bench Tuesday.
