Scouting Report
Updated May 19, 2026
Tyler Glasnow was placed on the 15-day injured list on May 10, 2026, with lower back spasms after exiting his start against the Houston Astros after just one inning on May 6. The injury occurred during warm-ups for the second inning, shortly after he recorded his 1,000th career strikeout (the fewest innings to reach this milestone in MLB history at 793 IP). MRI results showed nothing significant, and the team is in a holding pattern. Glasnow has a history of recurring back spasms throughout his career. Despite the injury, he has been performing at an elite level with a 2.72 ERA, 49 strikeouts in 39.2 innings, and leads MLB in hits per nine innings (4.4). He is on pace to break his personal strikeout record in 2026.
