Geraldo Perdomo Bio
Geraldo Rafael Perdomo (born October 22, 1999) is a Dominican professional baseball shortstop for the Arizona Diamondbacks of Major League Baseball. He made his major league debut in 2021, was named to his first MLB All-Star Game in 2023, and was a member of the Arizona Diamondbacks team that won the National League pennant in 2023.
Early Life and Background
Geraldo Rafael Perdomo is a native of the Dominican Republic and signed with the Arizona Diamondbacks as an international free agent on July 2, 2016. He began his professional career in the Dominican Summer League in 2017 and recorded 63 games with a .238 batting average, one home run and 11 runs batted in during his debut season.
Perdomo progressed through Arizona’s minor league system in the following seasons, developing a combination of contact hitting and speed that drew attention from the organization. In 2018 he played across three rookie- and Low-A level teams—the Arizona League Diamondbacks, the Missoula Osprey and the Hillsboro Hops—posting a combined .322 batting average with a .438 on-base percentage, four home runs, 24 runs batted in and 24 stolen bases in 57 games.
Path to Baseball
Perdomo moved steadily up the Diamondbacks’ ladder in 2019, opening the year with the Single-A Kane County Cougars and earning a promotion to the High-A Visalia Rawhide. Across 116 games that year he hit .275 with three home runs, 47 RBI and 26 stolen bases, then gained additional experience in the Arizona Fall League where he was selected to the Fall Stars Game.
To protect his rising prospect status, Arizona added Perdomo to its 40-man roster on November 20, 2020. That roster move set the stage for his promotion to the major leagues early in the 2021 season when the Diamondbacks called him up to fill in at shortstop.
