Geraldo Perdomo Bio
Geraldo Rafael Perdomo, born on October 22, 1999, is a Dominican professional baseball shortstop for the Arizona Diamondbacks of Major League Baseball (MLB). He made his MLB debut in 2021 and quickly developed into one of the franchise’s most reliable young infielders. In 2023, Perdomo was named to his first MLB All-Star Game and helped the Diamondbacks win their first National League pennant since 2001. He later added a Silver Slugger Award in 2025, cementing his reputation as one of the most complete young shortstops in the game.
Early Life and Background
Geraldo Rafael Perdomo was born in the Dominican Republic on October 22, 1999, and grew up surrounded by the country’s deep baseball culture. From a young age, he developed a passion for the sport, and his family supported his ambition to pursue a professional career. The Dominican Republic has long produced elite shortstops, and Perdomo’s calm defensive approach and contact-oriented bat reflected that heritage.
As a teenager, Perdomo stood out for his smooth defensive actions, strong throwing arm, and high baseball IQ. Those tools helped him attract attention from international scouts, leading to a life-changing opportunity to sign with a Major League organization before he finished his teenage years. That pathway eventually brought him into the Arizona Diamondbacks’ system and set the stage for his professional career.
Path to Major League Baseball
Perdomo signed with the Arizona Diamondbacks as an international free agent on July 2, 2016, beginning his climb through the minor leagues. He made his professional debut in 2017 with the Dominican Summer League Giants, batting .238 with one home run and 11 RBI over 63 games. In 2018, he moved through the rookie-level Arizona League Diamondbacks, the rookie-level Missoula Osprey, and the Low-A Hillsboro Hops, slashing a combined .322/.438/.460 with four home runs, 24 RBI, and 24 stolen bases across 57 games.
In 2019, Perdomo started with the Single-A Kane County Cougars and was promoted to the High-A Visalia Rawhide during the season, hitting .275 with three home runs, 47 RBI, and 26 stolen bases over 116 games. He capped that year with an appearance in the Arizona Fall League, where he was selected to play in the Fall Stars Game. He did not play in 2020 due to the cancellation of the minor league season caused by the COVID-19 pandemic, but the Diamondbacks added him to their 40-man roster on November 20, 2020, to protect him from the Rule 5 draft.
Geraldo Perdomo Career
Early Career (2017-2020)
Perdomo’s earliest professional seasons were spent establishing himself as a switch-hitting shortstop with plate discipline and dependable defense. He progressed steadily through Arizona’s Dominican, rookie, and Low-A affiliates, demonstrating a strong feel for the strike zone and consistent contact skills. His 2018 campaign, in which he hit .322 across three levels, was a sign that his bat was catching up to his defensive reputation.
He continued his climb through Single-A and High-A in 2019, reaching base at a strong clip and stealing bases at a steady rate. After the 2019 season, his selection to the Arizona Fall League’s Fall Stars Game further confirmed his status as one of the Diamondbacks’ top prospects, positioning him for an opportunity at the major league level.
MLB Debut and Rising Role (2021-2022)
On April 3, 2021, the Diamondbacks promoted Perdomo to the major leagues to fill in for the injured Nick Ahmed, and he made his MLB debut that night, starting at shortstop. In 11 games during his rookie campaign, Perdomo went 8-for-31 (.258) with one RBI, offering a glimpse of his poise on the big-league stage.
In 2022, Perdomo played a larger role for Arizona and produced one of the signature moments of his early career. On June 7, 2022, he hit his first career home run, a grand slam, off Jared Solomon of the Cincinnati Reds. He tied for the major league lead in sacrifice hits with 12, batting .195/.285/.262 with five home runs, 40 RBI, and nine stolen bases in 462 at-bats, and continued to refine his defensive game at shortstop.
All-Star and Pennant Season (2023)
The 2023 season marked Perdomo’s arrival as a frontline big leaguer. He made 144 appearances for the Diamondbacks, slashing .246/.353/.359 with career-highs in home runs (6), RBI (47), and stolen bases (16). His steady glove, disciplined at-bats, and improved pop made him a fixture in Arizona’s everyday lineup.
That summer, Perdomo was named to his first MLB All-Star Game, recognizing his emergence as one of the National League’s top young shortstops. He then played a key role as the Diamondbacks surged to their first National League pennant since 2001, reinforcing his value on a contending roster.
Setback and Return (2024)
On April 7, 2024, the Diamondbacks announced that Perdomo had suffered a torn meniscus in his knee that required surgery. Despite the injury, he returned to action and played 98 games for Arizona in 2024, batting .273/.344/.374 with three home runs, 37 RBI, and nine stolen bases. His willingness to play through rehab showed his durability and commitment to the team.
Arizona Diamondbacks Era (2025-Present)
On February 18, 2025, Perdomo agreed to a four-year, $45 million contract extension with the Arizona Diamondbacks, locking in a long-term future with the franchise. He responded with a career-best offensive season, winning the Silver Slugger Award in 2025 as one of the top-hitting shortstops in the league. Through June 20, 2026, his MLB career totals include a .252 batting average, 38 home runs, 252 RBI, and 72 stolen bases.
Driving Style and Strengths
Perdomo is a switch-hitting shortstop whose game is built on plate discipline, contact, and above-average speed. He works counts, draws walks, and uses the entire field, which makes him a tough out against both right- and left-handed pitching. Defensively, his smooth hands, strong arm, and pre-pitch positioning allow him to make difficult plays look routine at shortstop.
Notable Events and Milestones
Perdomo’s first career home run, a grand slam on June 7, 2022, against the Cincinnati Reds, remains one of his most memorable early moments. His first All-Star selection in 2023 and his role in Arizona’s 2023 National League pennant run stand as defining achievements.
