The Los Angeles Angels made a late audible on Monday, naming right-hander Chase Silseth their starting pitcher for the opener of a three-game series against the host Atlanta Braves.
Right-hander Griffin Canning, who was slated to start, told reporters he was dealing with "general soreness."
Silseth, 23, started just two of his 10 appearances this season, pitching to a 4.44 ERA and a 2-1 record. He last pitched for the Angels in a spot start against the New York Yankees on July 19 and struck out a career-high 10 batters, allowing one run in 5 2/3 innings to get the win.
