Gabriel Moreno is set to undergo an MRI today after leaving yesterday’s game due to lower back tightness, Nick Piecoro of the Arizona Republic writes. Manager Torey Lovullo told Piecoro and other media yesterday that Moreno was viewed as day-to-day, and the catcher downplayed the seriousness of the issue.
The MRI could simply be a precaution given Moreno’s early exit. Moreno took one plate appearance and caught the first two innings of the Diamondbacks’ 5-4 win over the Phillies, and Moreno ended the bottom of the second by throwing out Justin Crawford on a steal attempt. Once the bottom of the third began, however, James McCann had replaced Moreno behind the plate.
The D’Backs are better equipped than most teams in handling a day-to-day injury to a catcher, as McCann and Adrian Del Castillo are both already on the active roster. Since Arizona is already dealing with several injuries up and down the lineup, the club has been able to find at-bats for all three backstops, as Del Castillo (who himself started the season on the injured list with a minor calf strain) has made two starts at DH.
Despite this catching depth, obviously the Diamondbacks hope Moreno’s back issue won’t prevent him from soon returning to action. Moreno has a solid .275/.333/.400 slash line and five doubles over his first 45 plate appearances, making him one of the more productive hitters within an Arizona lineup that has yet to really get going this season.
Corbin Carroll has been a huge part of the Diamondbacks’ offense, beginning his season by hitting .333/.408/.690 with two homers and three triples in 49 PA. The hot start came in spite of a hamate surgery that cost Carroll most of Spring Training, but he is now dealing with a new injury — a minor hip problem that has sidelined him for the last two games. Lovullo said Carroll was available off the bench yesterday and might play as early as today, plus the hip injury wasn’t considered serious enough to merit an MRI for further examination.
Moving onto the pitching side of the injured list, Merrill Kelly is slated to make his season debut during Arizona’s upcoming road series in Baltimore, which begins on Monday. Lovullo told Piecoro and company that the plan is for Kelly to toss a bullpen session with the big league team this weekend, as a final check-up before Kelly is activated from the 15-day injured list.
Kelly’s injury was officially termed as intercostal nerve irritation. The bad back kept the right-hander on the shelf for most of Spring Training, and cost him the honor of being the Diamondbacks’ Opening Day starter. Kelly tossed 6 1/3 innings during three Cactus League games, five innings during a Triple-A rehab start on April 3, and 83 pitches over six innings of work during an extended Spring Training game last Thursday (as per reporter Jody Jackson).
With Kelly on the verge of returning, Piecoro feels Brandon Pfaadt will probably be removed from the rotation. Pfaadt is starting today’s game with the Phillies, so there might be a bit of extra pressure on the right-hander if he’s competing to keep his spot. Michael Soroka is the other starter whose rotation spot is less assured, but Soroka has a 2.87 ERA through 15 2/3 innings and three starts.
While Soroka has been solid, Pfaadt has a 6.75 ERA over 10 2/3 frames in his first two starts of 2026. If he isn’t starting, Piecoro writes that the D’Backs could use Pfaadt in an extended long relief role on the active roster, rather than send him to Triple-A to keep him stretched out as a proper starter.
Pfaadt should be removed from the rotation you can’t expect to win any games with the next Andy Sonnanstine out there throwing batting practice four years in a row.
