Is it time for the D’Backs to call up these top prospects from AAA?

Introduction

While it is still early in the season, I can’t help but notice that while the team is struggling at the MLB level, there’s several of the Dbacks top prospects playing very well for the D’Backs AAA level affiliate, the Reno Aces. There are also a couple veteran relief pitchers that have been pitching very well, who merit discussion, but who I won’t be discussing in this article. (NOTE: *We’re just just under a full month into the Minor League Baseball season, so small samples abound, especially with the relief pitchers. Just a few good/bad outings and games can turn these numbers upside down, so this is just a fun exercise. It’ll be another month before any Minor League stats should be taken seriously. All stats in this article through 28th April, 2026.*)

The Hot Hitting Prospects

Top 100 overall prospect Ryan Waldschmidt (Fangraphs |B-Ref player pages) has unsurprisingly been one of the Reno Aces best hitters. The 23 year old right handed hitting outfielder has played mostly center field in the 2026, but is capable of playing all three outfield positions competently. Through his first 131 plate appearences, he’s hit .303/.400/.505 with a 122 wRC+ and a .408 wOBA. Tommy Troy ( |), the 12th overall pick in the 2023, in his first 122 plate appearences is hitting .317/.405/.481 with a 120 WRC+ and .404 wOBA. Troy has seen the majority (60%) of his starts at second base, but surprisingly has spent a good chunk of time in left field and couple games worth of innings in center. LuJames ‘Gino’ Groover III ( |) through his first 127 plate appearances is hitting .340/.440/.427, with a 123 wRC+ and a .410 wOBA. He’s spent slightly more than half his time in the field this season at third base with the rest spent across the diamond at first. ’s ( | ) history has been discussed so much that I’m not going to discuss it here other than the very short version. Once a top prospect, legal issues that came as a result of cannabis induced psychiatric episode along with pandemic kept him away from baseball for three years. Robinson is probably not the star outfielder we thought he was, but he is a perfectly servicable outfielder with an intriguing mix of power and speed. In his first 110 plate appearences in 2026, Robinson is hitting .286/.400/.484 with a 119 wRC+ and a .402 wOBA. Robinson is capable of playing all three outfield position as well, with a better throwing arm than any of the other outfielder on the MLB roster. The biggest reason to not call up any of these four players is finding regular playing time, along with service time and roster considerations. Ryan Waldschmidt and Kristian Robinson are (arguably) an across the board upgrade over current Dback OFer , but if they’re only on the roster as the fourth outfielder, they won’t get as much playing time as needed to further develop as hitters. With his .524 OPS and 46 wRC+, has been a below average hitter in 2026, so bad that he’s been worth -0.3 WAR. Lourdes Gurriel may only have recently been activated of the Injury List, but he’s already matched Tawa in negative WAR despite having played in 10 fewer games. The aforementioned Barrosa’s job is arguably pretty safe, despite the 79 wRC+, he’s an above average outfielder who’s put up .2 WAR thanks to his defense. In a similar vein, the defensively gifted is once again struggling offensively, and while he still is putting up positive value, his defense isn’t **that** much of an upgrade over Waldschmidt’s to make his job safe either. Theoretically Waldschmidt and Robinson could replace Barrosa and Thomas , and while there would almost certainly be a drop off defensively, the potential for a massive offensive upgrade could might very well be worth it. Tommy Troy, who has the most defensive versatility thanks to his ability to play both infield and outfield, is an obvious choice to replace Tim Tawa on the roster. As long as the Ildemaro Vargas/Nolan Arenado experiment continues to be successful, and Jose Fernandez continues to rake, I can’t imagine we’ll see Groover anytime soon, unless just completely fails to provide any offense at DH. Which is unfortunate, as Groover statistically has been the best hitter on the Aces, while also having the exit velocity and batted ball data that legitimizes his production as more than a PCL induced fluke.
