The Colorado Rockies have put right-handed pitcher Chase Dollander on the 60-day injured list with what they suspect might be a UCL injury.

The young pitcher left a May 14 game against the Pittsburgh Pirates early due to right arm tightness. An MRI originally diagnosed an elbow sprain, but on Friday manager Warren Schaeffer revealed that a UCL surgery could be forthcoming.

"(Dollander) is going for a pre-op appointment soon, within a week," Schaeffer said. "Then, possibly, it is looking like surgery on the UCL. It's still not set in stone, but that's the way it's trending."

Dollander, 24, is 3-3 with a 3.89 ERA over 10 appearances this season, a significant improvement for the second-year player.

Last fall, the Rockies placed the then-rookie on the 15-day injured list to close the season after he suffered a knee injury. That closed a season that was ... well ... rocky. Dollander finished the campaign with a 6.52 ERA and a 2-12 record as he started 21 games.

Unfortunately, the stronger start in 2026 could soon give way to more disappointment.

"If anything happens to that area, your mind automatically goes to the worst-case scenario," Dollander said at the time of the injury.
