Spiers didn't factor into the decision in Sunday's 15-7 loss to the Cubs after striking out seven while allowing three runs on five hits and two walks over four innings.
After allowing three runs in his first two innings, Spiers salvaged his major-league debut by retiring the final six batters he faced. The 25-year-old right-hander had shown some strikeout upside in the minors, punching out 45 over his last six Triple-A starts (33 innings). With Hunter Greene, Brandon Williamson and Ben Lively all due to return from the COVID-19 list, Spiers will most likely return to the minors soon.
