Diamondbacks’ Merrill Kelly Scratched With Back Tightness, Awaiting MRI Results

Arizona Diamondbacks right-hander Merrill Kelly, the team’s slated Opening Day starter for 2026, was scratched from live batting practice after feeling mid-back tightness and underwent an MRI (February 21–22, 2026). Kelly had dealt with some tightness for about a week and a half; he left after roughly 10 pitches when discomfort in his left-mid back flared. The club was awaiting imaging results; manager Torey Lovullo said he appreciated Kelly being proactive rather than pushing through.

Kelly was listed day-to-day pending results. The D-backs have Zac Gallen and other rotation depth if Kelly needs time off.

What It Means for AthX

Until results are known, Kelly’s AthX price reflects uncertainty. Dynamic pricing will update with any missed time or role change. If he’s delayed, other D-backs starters get a short-term workload bump. Watch for the MRI update before adjusting positions.
