The Athletics will turn to pitcher Drew Pomeranz to start Thursday's game against the Blue Jays, reports MLB.com.
Scott Kazmir was the scheduled starter for Thursday's contest, but he was traded to the Astros. Pomeranz has started eight games this season and is 4-3 with a 3.58 ERA over 60 1/3 innings.
Manager Bob Melvin said Pomeranz will likely remain in the starting rotation moving forward.
