Merrill Kelly is making steady strides in his return from a back problem, and Arizona’s camp is watching closely. Positive signals from spring workouts suggest the veteran right-hander could rejoin the Diamondbacks’ rotation sooner than once feared, even if Opening Day remains unlikely.
Spring training progress: what the Diamondbacks are seeing
Arizona has shown encouraging signs during spring training. The club wants Kelly healthy and available for meaningful innings once the regular season begins. Team staff and media outlets have reported steady improvement in his activity level.

Recent on-field milestones for Merrill Kelly
Kelly completed a live batting-practice session that drew attention. According to reports from Steve Gilbert at MLB.com, the outing went without incident.
- Live BP went well, a clear step beyond light throwing.
- Next on the list is a formal bullpen session.
- If that proceeds smoothly, a Cactus League appearance could follow.
Those steps represent the typical phased approach clubs use to confirm a pitcher’s readiness. Kelly himself has described the plan as conditional, dependent on how his back responds day to day.
Medical treatment and rehab details
Kelly received a targeted injection in his back last week to reduce inflammation and pain. The treatment combined cortisone and lidocaine to help manage symptoms during rehab.
- Cortisone to control inflammation.
- Lidocaine for short-term pain relief.
- Follow-up work includes monitored throwing and recovery assessments.
After the procedure he was able to play catch without issue, an encouraging sign for both the player and the club’s medical staff.
Timeline: Opening Day and early-season expectations
While Kelly is trending in the right direction, the club appears cautious about penciling him into the Opening Day rotation. The current plan emphasizes a gradual ramp-up.
- Return to bullpen work under team supervision.
- One or more Cactus League starts to test durability.
- Potential insertion into the backend of the rotation early in the season.
Kelly has expressed optimism that he can be available to pitch for Arizona close to the start of the season, though nothing is final.
Why Kelly’s availability matters for Arizona
Getting Kelly back would add stability to a rotation in need of reliable innings. Last year the Diamondbacks finished 80-82 and struggled in the NL West. Reintegrating veteran starters is a priority.
- More rotation depth reduces bullpen strain.
- Veteran presence helps guide younger pitchers.
- Healthy Kelly increases the team’s margin for error.
Monitoring and next updates
Coaches and medical staff will continue to evaluate progress. Updates will likely appear after bullpen sessions or Cactus League appearances. Steve Gilbert’s coverage on MLB.com and posts on X have been primary sources for the latest information.
For now, the timeline remains optimistic but flexible. The club’s steps reflect a measured approach aimed at long-term availability rather than a rushed return.
