Diamondbacks' Tommy Henry: Designated for assignment
Rotowire
The Diamondbacks designated Henry (elbow) for assignment Tuesday.
Henry is slated to miss most, if not all, of the 2026 campaign after undergoing Tommy John surgery in June. His lengthy expected absence makes it unlikely that another team will be willing to pick him up off waivers, so the D-backs will take the opportunity to remove the injured lefty from their 40-man roster while protecting four prospects from the Rule 5 Draft.

Diamondbacks' Dylan Ray: Shielded from Rule 5 Draft
Rotowire
The Diamondbacks selected Ray's contract from Triple-A Reno on Tuesday.
Ray reached Triple-A for the first time in 2025 after posting a 3.93 ERA across 10 starts at Double-A Amarillo. However, he took a considerable step back following his promotion and accumulated a 6.30 ERA and 1.61 WHIP over 90 frames (18 starts) at Reno. Now protected from the Rule 5 Draft, the 24-year-old right-hander will most likely remain with the Aces until he shows improvement on the mound.

Diamondbacks' Jose Fernandez: Nabs 40-man spot
Rotowire
The Diamondbacks selected Fernandez's contract from Double-A Amarillo on Tuesday.
Fernandez enjoyed his best minor-league season yet while spending all of 2025 at Double-A, slashing .272/.321/.454 with 17 home runs, 81 RBI, 68 runs scored and 12 stolen bases across 510 plate appearances. His breakout season has earned him protection from the Rule 5 Draft in December and may also allow him to be promoted to Triple-A in 2026.

Diamondbacks' Kohl Drake: Selected to 40-man
Rotowire
The Diamondbacks selected Drake's (shoulder) contract from Triple-A Reno on Tuesday.
The 25-year-old southpaw was part of the return Arizona received from the Rangers for Merrill Kelly. Drake wasn't quite able to get comfortable with his new organization, however, allowing 17 earned runs over 16.2 innings across four starts before suffering a season-ending shoulder strain in late August. His addition to the 40-man roster will prevent another team from picking him up during the Rule 5 Draft in December, but the D-backs will likely need to see more from Drake before allowing him to make his big-league debut.

Diamondbacks' Mitch Bratt: Joins 40-man roster
Rotowire
The Diamondbacks selected Bratt's contract from Double-A Amarillo on Tuesday.
Bratt joined the D-backs organization from the Rangers at the trade deadline as part of the return for Merrill Kelly. After reporting to Amarillo, Bratt turned in a 3.98 ERA and 1.15 WHIP alongside a 42:5 K:BB across 31.2 innings (six starts). His addition to the 40-man roster will keep him in the organization beyond December's Rule 5 Draft, but he's likely to begin the 2026 campaign with Amarillo or Triple-A Reno.

Diamondbacks' Christian Montes De Oca: Outrighted off 40-man roster
Rotowire
The Diamondbacks outrighted Montes De Oca (back) to Triple-A Reno on Monday.
The transaction frees up a spot on the Diamondbacks' 40-man roster. Montes De Oca is recovering from surgery to repair a stress fracture in his back and it's not clear when he will be ready to pitch again. The reliever tossed 2.2 scoreless frames in his lone appearance for Arizona in 2025 and held a 4.07 ERA and 26:6 K:BB over 24.1 innings at Triple-A Reno.

Diamondbacks' Aramis Garcia: Back with Arizona
Rotowire
Garcia re-signed with the Diamondbacks on a minor-league contract last month, Matt Eddy of Baseball America reports.
Garcia spent the entire 2025 campaign in the Diamondbacks organization but was a member of the 40-man roster for just two brief stints in June and appeared in only two games for the big-league club. Arizona will bring back the 32-year-old to provide organizational catching depth at Triple-A Reno, where he slashed .266/.385/.481 with 14 home runs across 296 plate appearances last season.

Diamondbacks' Connor Kaiser: Loses 40-man spot
Rotowire
Kaiser cleared waivers Wednesday and was sent outright to Triple-A Reno, Alex Weiner of ArizonaSports.com reports.
Kaiser spent most of the season at Triple-A, where he slashed .236/.345/.406 with six homers, 31 RBI and 32 runs scored across 273 plate appearances. It's unknown whether the 28-year-old will elect to test the free-agent market, though he would be unlikely to attract more than a minor-league deal if he were to do so.

Diamondbacks' Casey Kelly: Outrighted to Triple-A
Rotowire
Kelly cleared waivers Wednesday and was sent outright to Triple-A Reno, Alex Weiner of ArizonaSports.com reports.
Kelly spent the vast majority of the 2025 season at Reno, where he finished with a 5.63 ERA and 1.65 WHIP through 115 innings. Now that the 36-year-old righty no longer owns a spot on Arizona's 40-man roster, he may elect free agency and look elsewhere for his next opportunity.

Diamondbacks' Kyle Nelson: Kicked off 40-man
Rotowire
Nelson cleared waivers Wednesday and was outrighted to Triple-A Reno, Alex Weiner of ArizonaSports.com reports.
Nelson appeared in just three games for the D-backs in 2025, giving up two earned runs over two innings. He didn't find much success in the minor leagues either, posting an 8.83 ERA and 1.64 WHIP across 34.2 frames. His poor performance will now cost him his roster spot as the offseason begins, and it's unknown whether he will exercise his right to elect free agency.

Diamondbacks' John Curtiss: Outrighted to Reno
Rotowire
Curtiss cleared waivers Wednesday and was sent outright to Triple-A Reno, Alex Weiner of ArizonaSports.com reports.
Curtiss finished the 2025 campaign with a 3.93 ERA and 0.93 WHIP alongside a 24:5 K:BB across 36.2 innings. However, with the Diamondbacks aiming to clear roster space before free agency begins, the 32-year-old righty will lose his place on the 40-man roster. He will have the option to elect free agency.
Diamondbacks' Lourdes Gurriel: Picks up player option
Rotowire
Gurriel (knee) exercised his $13 million player option for 2026 on Monday, Francys Romero of BeisbolFR.com reports.
Gurriel had right ACL surgery in September and will miss at least the first couple months of the 2026 season, which made picking up his option a fairly easy decision. The 32-year-old outfielder slashed .248/.295/.418 with 19 home runs over 129 games for the Diamondbacks before getting injured.

Diamondbacks' Jordan Lawlar: Plays center field in winter ball
Rotowire
Lawlar played center field Tuesday in his first game with Tigres del Licey in the Dominican Winter League.
Lawlar has never played the outfield as a pro, but he's being introduced to center field in winter ball as the Diamondbacks evaluate how the 23-year-old fits into their roster picture for 2026. The former top prospect is a shortstop by trade, but that position is being held down by Geraldo Perdomo with the big club. Lawlar played some third base last season for the Diamondbacks, but manager Torey Lovullo shied away from him down the stretch during their playoff push due to defense, instead preferring Blaze Alexander there. The hot corner is still an option for Lawlar, but a successful transition to outfield would solve a problem for the Diamondbacks, who will be without Lourdes Gurriel (knee) for most of the season. Lawlar's offensive potential is considered better than that of either Alek Thomas or Jake McCarthy.
