Diamondbacks‘ shortstop Geraldo Perdomo has emerged as one of the best shortstops in baseball in 2025. He hit .290 with 20 home runs, 100 RBI, and 27 stolen bases. He finished fourth in the National League MVP race.
Thanks to his breakout, Perdomo is now one of the best players at his position. Entering the 2026 season, he is ranked the No. 6 shortstop in MLB.
Perdomo, 26, took over the starting shortstop role in the Diamondbacks’ 2023 postseason run. With an All-Star campaign, the team felt comfortable parting ways with veteran Nick Ahmed.
Following a strong 2024 season, Arizona inked Perdomo to a four-year, $45 million extension. That’s a move that looks great a year later, especially since a club option could keep him in the desert through the 2030 season.
Perdomo ranked as the No. 24 player in MLB, with only Ketel Marte (No. 19) and Corbin Carroll (No. 9) being the only Diamondbacks ranked higher. All three star players are signed to team-friendly extensions, opening up their current competitive window.
Why Geraldo Perdomo Ranks Highly Among Shortstops
Perdomo provides excellent value in all facets of the game. He hits for average, is a solid power threat, plays good defense at a premium position, and is an elite baserunner. His 7.0 bWAR led all full-time position players.
What makes Perdomo great isn’t the physical talent, but excellent instincts that allow him to play at a high level.
Perdomo doesn’t have the fastest bat speed, but is one of the league’s most dynamic hitters. He isn’t the rangiest defender at shortstop, but he is the most sure-handed on the ones he gets to. He has below-average Sprint Speed metrics, but is an elite basestealer and baserunner.
Perdomo is the ideal leadoff hitter, someone who can grind out long at-bats and make pitchers pay for poor command. He can reach base via walks when the pitcher can’t throw strikes and has enough power to punish location mistakes. He had more walks (94) than strikeouts (83) in 2025, and set a career-high in home runs.
And when he does reach base, he’s a threat to steal his way into scoring position. Not only did he put up an impressive volume of steals (27), but he stole at a high percentage (84.6%).
Not only is he a great all-around player, but he’s emerged as the heart and soul of this Diamondbacks core. In past seasons, Lovullo challenged Perdomo to grow into that leadership role. It’s now something he’s embraced as he’s become one of the best players on the team.
His leadership was on display in August, when he pleaded with the media to leave Ketel Marte alone. Marte was the subject of a report from The Arizona Republic, in which some teammates grumbled about the star second baseman’s behavior.
Geraldo Perdomo’s Long-Term Outlook with the Diamondbacks
Perdomo is the Diamondbacks’ everyday shortstop for the foreseeable future. He’s been indispensable, starting 160 of the team’s 162 games in the field. Not only that, he’s under a team-friendly extension for up to the next five seasons ($60MM total).
Not only is Perdomo entrenched at shortstop, but he’s entrenched at the top of Arizona’s lineup. Manager Torey Lovullo made the change to move his star shortstop to the leadoff spot. Lovullo experimented with that earlier in the season, but made the move permanent starting on August 12.
Perdomo is the first of three elite hitters at the top of the Diamondbacks lineup. Ketel Marte and Corbin Carroll hit behind him, giving any starting pitcher an immediate challenge. All three hitters produced a wRC+ of 138 or better in 2025, ranking in the Top 10 of qualified National League hitters.
The Diamondbacks’ farm system is weak at the shortstop position. With Perdomo locked up for the next five seasons, time is on their side to draft and develop one. It also wouldn’t be a shock if Arizona signed him to another extension in a few years.
