As a swingman who has been up and down from the minor leagues several times this season, Cooper Criswell’s job is to be ready when he’s called upon. When the team needs him, it’s Criswell’s job to provide multiple innings, or, as was the case Friday night, a spot start. With Richard Fitts optioned on the recent road trip and opening a temporary spot in the rotation, Criswell seized the opportunity and turned in what was likely the second-best start of his major league career. Criswell scattered seven hits over seven innings to the Houston Astros, allowing just one run in a game the Sox went on to win, 2-1, in 10 innings.
