Overview
- The Colorado Rockies transferred right-hander Chase Dollander to the 60-day injured list on Saturday, June 13, after he exited a May 14 start with right-arm tightness.
- An MRI in May showed a right elbow sprain, and the club says rehab produced limited improvement, prompting second medical opinions and the upcoming pre-op appointment.
- Manager Warren Schaeffer said the situation is "trending" toward UCL surgery, though the procedure has not been formally scheduled or confirmed.
- The move creates an immediate vacancy in Colorado’s starting rotation and forces the team to adjust pitching plans while it awaits a medical decision and a potential long recovery timetable.
- Dollander, the No. 9 pick in the 2023 draft, had shown marked improvement in 2026 with a 3.89 ERA and 47 strikeouts in 44 innings, and a UCL reconstruction would interrupt his rising career and require many months of rehab.
