Diamondbacks optioned Yilber Diaz, Dylan Ray to Triple-A Reno

Arizona optioned right-handers Yilber Diaz and Dylan Ray to Triple-A Reno and reassigned catcher Gavin Logan to minor-league camp, part of a spring training cut that left 62 players in major-league camp, Alex Weiner tweeted March 5.

Bruno Mulé of FantasyPros chronicled Diaz’s recent role change and command issues: "Diaz transitioned to a relief role at Triple-A Reno last season and issued 73 walks across 57 innings in the minors. He allowed four runs on three hits and two walks over 1.2 innings this spring. (Alex Weiner)" Diaz’s heavy walk totals in the minors underline why Arizona will station him in Reno rather than keep him in the big-league bullpen mix to open the season.

RotoWire framed Dylan Ray’s assignment as organizational depth with a specific role: "Ray was added to Arizona's 40-man roster this offseason but never had a real chance to crack the Opening Day roster. The 24-year-old permitted four runs (two earned) with a 2:2 K:BB over 1.1 frames in his lone Cactus League appearance. Ray will open the 2026 season in the Triple-A Reno rotation." Ray’s 40-man status and the RotoWire projection that he will start in Reno suggest the Diamondbacks view him as a potential near-term option if Arizona needs a rotation piece.

Gavin Logan was listed among the reassigned players to minor-league camp in Alex Weiner’s roster summary, which also reproduced the club’s trimmed roster count: "Arizona Diamondbacks roster moves: Optioned to Triple-A Reno: RHP Yilber Diaz RHP Dylan Ray Reassigned to Minor League camp: C Gavin Logan 62 players in camp." No statistical detail for Logan was provided in the accounts that announced the move.

Social posts from local channels framed the assignments as the first Reno arrivals of the season, with Facebook and Instagram copy reading, "The first Reno Aces of 2026 🤩 The Arizona Diamondbacks have optioned RHPs Yilber Diaz and Dylan Ray to Triple-A Reno!" Those posts signal an immediate fan-facing impact for Reno Aces supporters who will see both arms in early-season Southern League competition and affiliated promotions.

For Triple-A Reno, the moves load the early roster with a 24-year-old starter who is on the 40-man and a reliever coming off a role change and pronounced control problems. For the Diamondbacks, optioning Ray and Diaz while trimming camp to 62 players preserves organizational flexibility: Ray is positioned to start in Reno per RotoWire, and Diaz heads to Reno to work on command after a minor-league season that included 73 walks in 57 innings.
