Can Alek Thomas Still Be the Diamondbacks' Centerpiece? A once-promising prospect, Alek Thomas, now faces a crossroads in his career. Remember that electrifying 2023 NLCS homer off Craig Kimbrel? It felt like a glimpse of the superstar we were promised. But here's where it gets controversial: despite that moment, Thomas hasn't lived up to the hype. Let's dive into his 2025 performance and the questions it raises about his future.

From Prospect Phenom to Stalled Development
Alek Thomas exploded onto the scene in 2021, dominating the minors with a .313 AVG, 18 HR, and a staggering .953 OPS, all while showcasing gold-glove caliber defense in center field. MLB.com ranked him the Diamondbacks' top prospect and 18th overall, ahead of future stars like Corbin Carroll and Elly de la Cruz. The future seemed bright.
The Unfulfilled Promise
Fast forward to 2025, and the narrative has shifted. Thomas's complex swing, characterized by a pronounced leg kick and excessive bat waggle, continues to be his Achilles' heel. He struggles mightily against breaking balls (.233 xBA) and offspeed pitches (.213 xBA). Brief stints in the minors aimed at simplifying his mechanics offered temporary relief, but old habits die hard. The result? A disappointing 40.2% topped ball rate, leading to weak grounders and a lack of offensive impact.
Defensive Decline Adds to the Woes
Adding insult to injury, Thomas's once-elite defense has regressed. His Fielding Run Value, a metric from Baseball Savant, has plummeted from +7 in his 2022 debut to a mere 0 in 2025, indicating league-average performance in center field. Lower-body injuries, including a hamstring issue that limited him to 39 games in 2024, likely contribute to this decline, further hampered by Chase Field's spacious outfield.
A 0.1 WAR in his fourth MLB season with over 400 plate appearances is a stark contrast to his 1.4 WAR rookie campaign in fewer games. This trajectory raises serious concerns about his long-term viability as an everyday center fielder.
2026: A Make-or-Break Year?
As of December 2025, Thomas is penciled in as Arizona's starting center fielder. However, his league-average (or worse) production at a premium defensive position casts doubt on his ability to contribute to a contending team.
And this is the part most people miss: the Diamondbacks' offseason moves could significantly impact Thomas's role. Acquiring a superior center fielder would make him expendable, potentially becoming trade bait to strengthen the bullpen, a known area of need for GM Mike Hazen.
Internal competition adds another layer of complexity. Shifting Corbin Carroll back to center field, his natural position, could be an option if prospects like Ryan Waldschmidt emerge in right field, further marginalizing Thomas's role.
A Personal Note and a Call for Discussion
I desperately want to believe in Alek Thomas. That NLCS home run remains one of my most cherished Diamondbacks memories. But four seasons of offensive stagnation and defensive regression paint a different picture. His tools suggest untapped potential, but time is ticking.
Is it too late for Thomas to rediscover his prospect magic? Can he simplify his swing and regain his defensive prowess? Or is his role as an everyday player already a thing of the past? Let's hear your thoughts in the comments.
