Caratini went 2-for-4 with a three-run home run, an additional run and a walk against the Angels in Saturday's 10-4 victory.
Caratini blew the game open for Houston in the third inning, belting a three-run shot off Angels starter Reid Detmers to increase the Astros' lead to 6-1. It was the third straight start for Caratini, who played first base Saturday after serving as Houston's catcher Thursday and Friday. Caratini is batting .289 (13-for-45) with five RBI through 15 games in September.
