Singleton is not in the lineup Wednesday for Game 2 of the American League Wild Card Series versus the Tigers, Chandler Rome of The Athletic reports.
Lefty Tyler Holton is opening for the Tigers, with righty Reese Olson seen as likely to cover multiple innings in relief. Singleton could enter mid-game when a righty is in there, but the Astros will go with the switch-hitting Victor Caratini again at first base to begin the contest.
