The Arizona Diamondbacks just dropped a bombshell that has baseball fans buzzing: their 2026 spring training roster is here, and it’s packed with talent that could redefine the team’s future. But here’s where it gets exciting: top prospect Ryan Waldschmidt is joining the big league stars in the clubhouse, setting the stage for what could be a breakout year. And this is the part most people miss—Waldschmidt isn’t alone. Infielder Tommy Troy, infielder LuJames Groover, outfielder Druw Jones, and pitcher Daniel Eagen are among the non-roster invitees who’ll be training alongside the majors at Salt River Fields. Could one of them crack the Opening Day lineup? It’s not out of the question.
Pitchers and catchers report on February 10, with full squad workouts kicking off on February 15. Mark your calendars for February 20, when the Diamondbacks face the Colorado Rockies in their Cactus League opener. But let’s dive deeper into the players who could steal the show.
Waldschmidt, the No. 31 pick in the 2024 MLB Draft, had a scorching summer in Double-A Amarillo last year. His August performance—a 1.143 OPS, 13 extra-base hits, and 12 steals in 26 games—earned him Texas League Player of the Month honors. Over 66 games, he slashed .309 with a .921 OPS, nine home runs, and 19 steals, catapulting him into the national spotlight. Controversial take: Is he ready for the majors in 2026? Some say yes, while others argue he needs more seasoning. What do you think?
Tommy Troy, Arizona’s 2023 first-round pick, bounced back strong in 2025, reaching Triple-A Reno. His 15 home runs and 24 steals in 125 games showcased his power-speed combo, and his reps in center field added a layer of versatility. LuJames Groover, a Double-A staple in 2026, hit .309 with an .833 OPS, primarily at third base. But with Nolan Arenado now manning the hot corner, where does Groover fit in? It’s a question that could spark heated debates.
Speaking of the infield, the Diamondbacks’ trade for Arenado, paired with shortstop Geraldo Perdomo and second baseman Ketel Marte, has solidified the middle of the diamond. The outfield, however, is a different story. Aside from Corbin Carroll, there’s room for competition—and that’s where prospects like Waldschmidt and Jones could make their move. Bold prediction: Don’t be surprised if a non-roster invitee earns a spot by Opening Day.
General manager Mike Hazen hinted at this possibility in January: ‘Yes, there’s some guys in our system that could come in and challenge for spots on the major league team.’ But he stopped short of naming names, leaving fans to speculate. The bullpen is another area ripe for competition, with no clear closer and veterans like Derek Law and Jonathan Loaisiga vying for roles as non-roster invitees.
By Opening Day, the Diamondbacks must trim the roster to 26 players. With 40 players on the 40-man roster and 32 non-roster invitees, the battle for spots will be fierce. From right-handed pitchers like Juan Burgos and Corbin Burnes to lefties like A.J. Puk and Eduardo Rodriguez, the pitching staff is loaded. Catchers Adrian Del Castillo and Gabriel Moreno will anchor the battery, while infielders like Blaze Alexander and Jordan Lawlar fight for playing time.
The outfield mix includes Jorge Barrosa, Lourdes Gurriel Jr., and Alek Thomas, but don’t count out Kristian Robinson or A.J. Vukovich. Here’s the real question: With so much talent, who will rise to the top? And will the Diamondbacks’ bold moves pay off in 2026? Let us know your thoughts in the comments—this roster is too exciting not to discuss!
