The Houston Astros announced that right-handed pitcher Gerrit Cole was scratched from his Tuesday start against the Chicago White Sox after experiencing right hamstring discomfort during warm-ups.
Chris Devenski got the road start in Cole's place.
Cole and Justin Verlander make up one of the more effective one-two punches in the league, and the former has followed up his head-turning 2018 effort with a 2.87 ERA, 0.98 WHIP and a league-leading 226 punchouts in 156.2 frames in another All-Star campaign in 2019.
The 28-year-old has suffered injuries that have kept him off the mound before.
