Caratini is out of the lineup for Sunday's game against the Royals.
Caratini picked up starts at first base and catcher Friday and Saturday, respectively, but he'll hit the bench for the finale. Yainer Diaz will work behind the plate Sunday, while Jon Singleton gets the nod at first base. The Astros are likely to rotate Caratini, Singleton and Zach Dezenzo at first base until somebody performs well enough to take control of the job.
