Geraldo Perdomo Bio
Geraldo Rafael Perdomo (born 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 was selected to his first MLB All-Star Game in 2023. That same year, he helped the Arizona Diamondbacks win their first National League pennant since 2001. A switch-hitter with strong defensive instincts, Perdomo has developed into one of the franchise’s cornerstone players.
Born in the Dominican Republic, Perdomo signed with the Arizona Diamondbacks as an international free agent in 2016 and has spent his entire professional career within the organization. In early 2025, he agreed to a four-year contract extension that secures his place with the club through 2029.
Early Life and Background
Geraldo Rafael Perdomo was born on October 22, 1999, in the Dominican Republic. He grew up in a country where baseball serves as the dominant cultural pastime, and the sport is woven into everyday community life from an early age. Like many Dominican prospects, he developed his game on local sandlots and amateur fields before drawing the attention of Major League Baseball scouts.
Details about his family background and formal education have not been publicly confirmed, and Perdomo has largely kept his personal early life private. What is known is that his talent as a switch-hitting shortstop made him one of the more intriguing teenage free-agent prospects available in the 2016 international signing period. On July 2, 2016, the Arizona Diamondbacks signed him as an international free agent, formally launching his professional career.
Path to Baseball
Perdomo began his professional journey in 2017, playing for the Dominican Summer League Giants, the Arizona Diamondbacks’ affiliate in the Dominican Summer League. Over 63 games, he batted .238 with one home run and 11 runs batted in (RBI), gaining his first taste of organized baseball outside his homeland.
In 2018, Perdomo moved to the United States and split time across three affiliates: the rookie-level Arizona League Diamondbacks, the rookie-level Missoula Osprey, and the Low-A Hillsboro Hops. He produced a combined slash line of .322/.438/.460 with four home runs, 24 RBI, and 24 stolen bases across 57 games, establishing himself as a polished young shortstop. The 2019 season saw him progress through the Single-A Kane County Cougars and High-A Visalia Rawhide, where he played 116 games and hit .275 with three home runs, 47 RBI, and 26 stolen bases.
After the 2019 season, Perdomo played in the prestigious Arizona Fall League and was selected to the Fall Stars Game, an honor reserved for the league’s top prospects. He did not play in 2020 because the minor league season was cancelled due to the COVID-19 pandemic. On November 20, 2020, the Diamondbacks added him to their 40-man roster, protecting him from the upcoming Rule 5 draft.
Geraldo Perdomo Career
Early Career (2017–2020)
Perdomo’s developmental years were marked by steady advancement through the Diamondbacks’ farm system. From his Dominican Summer League debut in 2017 through his High-A assignment with Visalia in 2019, he showed the tools that scouts had projected: a smooth defensive game at shortstop, a patient approach at the plate, and speed on the basepaths. His combined 50 stolen bases across the 2018 and 2019 seasons highlighted his ability to impact games in multiple ways.
The cancelled 2020 minor league season tested his development, but his placement on the 40-man roster that November signaled that the Diamondbacks viewed him as part of their long-term core. That decision set the stage for his MLB debut the following spring.
MLB Debut and Rookie Season (2021)
On April 3, 2021, the Diamondbacks promoted Perdomo to the major leagues to fill in for the injured Nick Ahmed. That same night, he made his MLB debut, starting at shortstop in place of Josh Rojas. Across 11 games during his rookie campaign, Perdomo went 8-for-31, batting .258 with one RBI. The cup of service offered a glimpse of the player Arizona had been developing for nearly five years.
Establishing Himself (2022–2023)
Perdomo delivered a memorable first career home run on June 7, 2022, a grand slam off Jared Solomon of the Cincinnati Reds. That season he tied for the major league lead in sacrifice hits with 12, finishing with a .195/.285/.262 slash line, five home runs, 40 RBI, and nine stolen bases across 462 at-bats. His willingness to handle the small aspects of the game drew praise from coaches and teammates.
The 2023 campaign marked Perdomo’s breakthrough. He appeared in 144 games, slashing .246/.353/.359 while setting career highs in home runs (6), RBI (47), and stolen bases (16). His strong all-around play earned him a selection to the 2023 MLB All-Star Game, his first Midsummer Classic. He capped the year by helping the Arizona Diamondbacks capture their first National League pennant since 2001, cementing his role as a key piece of the franchise’s resurgence.
Resilience and Contract Year (2024–2025)
Perdomo’s 2024 season was interrupted on April 7 when the Diamondbacks announced that he had suffered a torn meniscus in his knee requiring surgery. He returned to action and played 98 total games, batting .273/.344/.374 with three home runs, 37 RBI, and nine stolen bases. His ability to come back and contribute following a significant injury underscored his durability and importance to the club.
On February 18, 2025, Perdomo agreed to a four-year, $45 million contract extension with the Diamondbacks, locking him in through 2029. The deal reflected both his performance and his standing within the organization as a homegrown cornerstone.

His switch-hitting ability gives Arizona lineup flexibility, while his sure hands and strong instincts at shortstop make him a steady presence in the field.
