Arizona Diamondbacks pitcher Merrill Kelly is advancing in his recovery and moving closer to rejoining the team after experiencing mid-back tightness. Diagnosed with intercostal nerve irritation, Kelly was paused from throwing during spring camp but has avoided placement on the Injured List. This progress improves his outlook for reentering the starting rotation as the season begins.
Recent Throwing Sessions Indicate Positive Development
Kelly recently completed a live batting practice session, which went smoothly, marking an important step in his rehabilitation. According to Steve Gilbert of MLB.com, Kelly expects to follow this with a bullpen session and hopes to pitch in a Cactus League game soon. Gilbert noted on Twitter,
“Provided he continues to feel good, [Kelly] thinks he will throw a bullpen and then get into a Cactus League game. All subject to change but trending positively.”
Potential Timeline for Return and Team Impact
While the Diamondbacks have not finalized their starting pitcher for the season opener at Dodger Stadium, Kelly’s recovery suggests he could be ready for their upcoming home series against the Detroit Tigers if no setbacks occur. His gradual return after missing early camp throwing reinforces a hopeful scenario for Arizona’s rotation depth. This timeline remains tentative but reflects ongoing cautious optimism around Kelly’s condition.
All went well with @Dbacks Merrill Kelly’s live BP session. Provided he continues to feel good, he thinks he will throw a bullpen and then get into a Cactus League game. All subject to change but trending positively.
