Merrill Kelly Fantasy Stats

Arizona Diamondbacks right-hander Merrill Kelly (back) will start the 2026 season on the 15-day injured list to build up his workload, and he will start a backfield game at the team's spring training complex this Saturday, according to Alex Weiner of Arizona Sports. If all goes according to plan, Kelly will make rehab outings for Triple-A Reno on April 3 and April 3 and then prepare to rejoin Arizona's starting rotation for his next appearance in his 2026 debut. The 37-year-old veteran pitched into the third inning in Monday's exhibition game against the Cleveland Guardians and got his pitch count up to 52. He allowed five runs, including two home runs, but he felt good about how his body felt. Kelly still has some work to do to fine-tune his mechanics, but barring a setback, he should be ready to return in April. He had a 3.52 ERA, 1.11 WHIP, and 167:48 K:BB in 184 innings over 32 starts in 2025 with Arizona and the Texas Rangers in his seventh year in the big leagues. Kelly is a savvy vet when healthy, but his fantasy upside is limited due to a below-average strikeout rate and increased injury volatility at his age.

Arizona Diamondbacks starting pitcher Merrill Kelly (back) will open the season on the 15-day injured list, manager Torey Lovullo told Alex D'Agostino of Diamondbacks on SI. The move was widely expected, but now confirmed by the Snakes' skipper as he announced the team's Opening Day rotation. Kelly entered camp as the Diamondbacks' projected No. 1 starter before dealing with the back issue. Now, he'll open the year on the IL. Lovullo didn't offer a timetable for his return, but the starter could pitch in a game as soon as April 7, if the team chooses to backdate his IL placement. Missing only 12 days would be a decent outcome for Kelly, who is looking to build on an impressive 2025 campaign that included a 3.76 FIP, 8.17 K/9, and 2.35 BB/9.

Arizona Diamondbacks starting pitcher Merrill Kelly (back) expects to open the regular season on the injured list, according to Steve Gilbert of MLB.com. Kelly experienced back discomfort on February 21, and while he was able to throw 1.2 innings in a Cactus League game this past Friday, it sounds like he won't be in the Snakes' rotation on Opening Day. On one hand, it's unfortunate news for the Diamondbacks and Kelly, who was projected to be the Opening Day starter after posting an impressive 3.76 FIP with 3.48 K/BB last year. On the other hand, Gilbert notes that the Diamondbacks can backdate Kelly's IL placement to three days before Opening Day, so he'd only miss the first 12 days of regular-season action. All things considered, that's just a few starts and should be enough to ensure he's fully healthy for a long season. Managers can afford to be a little patient with Kelly if it means that he'll be at peak health and productivity going forward. He currently ranks as the #72 starter in RotoBaller's latest fantasy baseball rankings for 2026.

Arizona Diamondbacks starting pitcher Merrill Kelly (back) is set to make the start in his team's spring training game on Friday against the Kansas City Royals, per Alex Weiner of Arizona Sports. Kelly was sidelined early in camp with a back injury, but he was able to make it through a live batting practice session this past Sunday and appears on track to progress to game action. The 37-year-old may not be fully built up to his normal pitch count in his first start or two of the season, but he should have a chance to be ready for Opening Day barring any setbacks. Across 184 innings (32 starts) split between the Diamondbacks and Texas Rangers in 2025, Kelly posted a 12-9 record with a 3.52 ERA, 1.11 WHIP, and 167 strikeouts. He is locked into a rotation spot in Arizona and projects as a quality late-round innings eater for fantasy managers.

Arizona Diamondbacks starting pitcher Merrill Kelly (back) was able to throw a successful live batting practice session on Sunday. According to Steve Gilbert, Kelly felt good during the session and everything went well. The next step will likely be Kelly throwing a bullpen session before getting into game action. Barring any setbacks, Kelly should be ready in time for Opening Day. In 2025, Kelly posted a 3.52 ERA, 1.11 WHIP, and a 167/48 K/BB ratio across 32 starts. The 37-year-old pitched well last season, but a regression is possible given his age. If healthy, Kelly could be an interesting late-round option, but he's unlikely to surpass last year's numbers.

Arizona Diamondbacks starting pitcher Merrill Kelly (back) is slated to throw a bullpen session on Thursday, per manager Torey Lovullo. The veteran has been on a throwing program, tossing from up to 60 feet as recently as Tuesday, and the bullpen session is the next step in that process. At some point, he'll face live hitters and eventually make his spring debut if he does not experience any setbacks. For now, he's optimistic about being ready for Opening Day, and the 37-year-old is coming off a solid 2025 campaign in which he recorded a 3.52 ERA, 1.11 WHIP, and struck out 167 batters in 184 innings pitched. A 3.95 SIERA points to some possible regression, and at pick 205 in Yahoo! leagues, he looks a bit pricey, especially given his RotoBaller rank of 262 overall, but if you can scoop him up later than his ADP, the right-hander could be a decent back-end fantasy rotation piece.

Arizona Diamondbacks starting pitcher Merrill Kelly (back) is throwing from out to 60 feet, per manager Torey Lovullo. The veteran is dealing with a back injury, but played catch on Sunday, and this is a continuation of a throwing progression that would next get him into a bullpen session. The 37-year-old is optimistic about being ready for Opening Day and would likely join the backend of the Arizona rotation when the season opens if all goes to plan. The right-hander tossed 184 innings in 2025, posting a 3.52 ERA, 1.11 WHIP, and 167 strikeouts (15.9 percent K-BB%). With an ADP of around pick 200, Kelly is being taken at the back end of most drafts, so it is worth monitoring his progress to make sure he stays on track.

Arizona Diamondbacks starting pitcher Merrill Kelly (back) received cortisone and lidocaine shots in his back last week and was able to play catch on Sunday without issue, per Steve Gilbert of MLB.com. Gilbert reports that Kelly is "optimistic" he will be able to "pitch at the backend" of Arizona's rotation to start the season. The 37-year-old was traded by the Diamondbacks to the Texas Rangers at the 2025 trade deadline, but returned to Arizona in free agency this offseason. Across 184 innings (32 starts) split between the Diamondbacks and Rangers in 2025, Kelly posted a 12-9 record with a 3.52 ERA, 1.11 WHIP, and 167 strikeouts. It's not a great sign that he's dealing with back issues in spring, particularly given his age. However, it appears as though Kelly could avoid missing time, even if it requires him ramping up to a full workload in his first couple starts of the regular season.

Arizona Diamondbacks manager Torey Lovullo said that the team is "holding out hope" that if right-hander Merrill Kelly (back) can ramp up his throwing "sooner than later," that he'll have time to get ready to pitch in the second series of the season and "avoid the injured list," according to The Arizona Republic's Nick Piecoro. It was believed that the 37-year-old would open the 2026 season on the IL, and that's still likely to be the outcome, with the D-backs probably preferring not to rush the veteran hurler back early in the year. When healthy, Kelly is a top-of-the-rotation arm for Arizona, even though his fantasy baseball value is limited due to his lack of strikeouts (22% career strikeout rate). Kelly opened the 2025 season with the D-backs before being traded to the Rangers at midseason. He finished with a 3.52 ERA, 1.11 WHIP, and 167:48 K:BB in 184 innings (32 starts). An aging pitcher with an injury concern heading into the season isn't exactly a strong late-round fantasy target.

Arizona Diamondbacks manager Torey Lovullo confirmed on Wednesday that veteran right-hander Merrill Kelly (back) will not start on Opening Day due to a back injury he picked up in camp, according to Alex Weiner of Arizona Sports. The good news is that Kelly's MRI results haven't shown any structural damage, so he could have a minimal stay on the injured list to begin the 2026 regular season. With Kelly now unable to be ready for the start of the year, right-hander Michael Soroka could round out the Snakes' Opening Day rotation in Arizona. Kelly features a diverse arsenal and has plenty of experience in the big leagues, but his lack of putaway stuff already made him a low-ceiling starting pitcher for fantasy purposes, and his back injury now make his even less attractive as rotation depth in mixed leagues in 2026.
