Houck (0-1) took the loss against the Cubs on Sunday, allowing three runs on four hits and no walks with one strikeout over three innings.
Houck made his first major-league start in 503 days after a lengthy rehab from elbow surgery and was burned by two homers from Alex Bregman. The southpaw has worked just 11 innings between the majors and minors this year, and it's unclear what his role will be with the Red Sox as they head into the postseason.
