He made his MLB debut in 2024 and is regarded as one of the organization’s top young position prospects. A native of Miami, Florida, Del Castillo plays a power-hitting style behind the plate and has quickly become a fan favorite in Arizona.
Drafted in the second round of the 2021 MLB Draft, Del Castillo progressed steadily through the minor leagues before delivering a memorable rookie campaign. He is best known for hitting a walk-off home run in his first major league at-bat, a first in Diamondbacks history, and for winning Pacific Coast League Most Valuable Player honors that same year.
Early Life and Background
Adrian Jose Del Castillo was born on September 27, 1999, in Miami, Florida, USA. He grew up in a region long associated with competitive baseball, and his surroundings helped shape his early interest in the sport. From a young age, he showed the offensive instincts that would later define his professional profile.
Del Castillo attended Gulliver Preparatory School in Miami, Florida, where he starred on the baseball team. As a senior in 2018, he hit .527 with 15 home runs and 35 runs batted in (RBIs), establishing himself as one of the top high school catchers in the country. His performance that season caught the attention of MLB scouts and led to his selection by the Chicago White Sox in the 36th round of the 2018 Major League Baseball Draft. Rather than sign professionally, he chose to continue his baseball development at the collegiate level.
Path to Baseball
Following his senior year of high school, Del Castillo enrolled at the University of Miami to play for the Miami Hurricanes baseball program. The move gave him the opportunity to face elite college pitching and to refine his catching skills. In 2019, his freshman season, he started 61 games and hit .331/.418/.576 with 12 home runs and 72 RBIs, earning All-Atlantic Coast Conference Freshman Team and Second Team honors, along with Freshman-All-American recognition from multiple outlets. He split time across right field, catcher, third base, and designated hitter during that year.
During the summer of 2019, Del Castillo played in the Cape Cod Baseball League for the Wareham Gatemen, a prestigious collegiate wood-bat league. His sophomore season in 2020 saw him hit .358 with two home runs and 15 RBIs over 16 starts before the season was cut short by the COVID-19 pandemic. In his junior year of 2021, he appeared in 54 games and batted .275 with three home runs and 37 RBIs. After that season, the Arizona Diamondbacks selected him in the second round, with the 67th overall pick, of the 2021 Major League Baseball Draft. He signed with the club for a $1 million signing bonus.
Adrian Del Castillo Career
Early Career (2021–2022)
Del Castillo began his professional career in 2021 with the Rookie-level Arizona Complex League Diamondbacks before being promoted to the Visalia Rawhide of the Low-A West after just two games. Over 24 games that season, he slashed .265/.367/.422 with one home run, 14 RBIs, and six doubles. The brief but productive introduction offered a glimpse of the offensive upside that Arizona had valued when it drafted him.
In 2022, Del Castillo was assigned to the Hillsboro Hops of the High-A Northwest League to start the year and also saw time with the ACL Diamondbacks and Visalia. Over 86 games between the three affiliates, he batted .210 with seven home runs and 31 RBIs. Although the batting average dipped, the power production remained steady, and the organization remained committed to his long-term development behind the plate.
Minor League Breakthrough (2023)
Del Castillo opened the 2023 season with the Amarillo Sod Poodles of the Double-A Texas League. He played well enough to earn a mid-July promotion to the Reno Aces of the Triple-A Pacific Coast League. Over 100 combined games that year, he hit .263 with 14 home runs and 68 RBIs, demonstrating both durability and run-producing ability. The season marked his emergence as a legitimate upper-minors catching prospect.
Reno Aces Dominance and MLB Debut (2024)

In 100 games for the Aces, he batted .319/.403/.608 with 24 home runs and 70 RBIs, showcasing the kind of on-base plus power profile that scouts had projected when he was drafted. On August 6, 2024, his strong play earned him a spot on the Arizona 40-man roster and his first promotion to the major leagues.
On August 9, 2024, against the Philadelphia Phillies, Del Castillo became the first player in Arizona Diamondbacks franchise history to hit a walk-off home run as his first major league hit. The moment instantly elevated his status among the team’s fan base. On August 18 against the Tampa Bay Rays, he hit a three-run home run that tied the game in the ninth inning, though Arizona ultimately fell in extra innings. The following day, August 19, against the Miami Marlins, he hit his first career grand slam and recorded six RBIs in front of friends and family in his hometown of Miami. In 25 games during his rookie campaign, Del Castillo slashed .313/.368/.525 with four home runs and 19 RBIs. He was also named the Pacific Coast League Most Valuable Player for his work with Reno that year.
Arizona Diamondbacks Era (2024–Present)
After his 2024 cup of tea in the majors, Del Castillo was optioned to Triple-A Reno to begin the 2025 season, with the Diamondbacks choosing to manage his development and playing time at the highest level of the minors. The decision reflected both the organization’s confidence in his long-term role and the depth of catching talent on the major league roster. When his number has been called, he has consistently rewarded the club with impactful at-bats and steady work behind the plate.
Driving Style and Strengths
Del Castillo is recognized for his right-handed power and his ability to drive the ball to all fields. He pairs that offensive skill set with above-average plate discipline, allowing him to work counts and get on base at a high clip. Defensively, he continues to grow into the catching role, with the Diamondbacks investing in his receiving and game-calling development through their minor league system.
Notable Events and Milestones
Del Castillo’s most signature moment came on August 9, 2024, when he hit a walk-off home run for his first major league hit, a feat no Diamondbacks player had accomplished before.

2025 Season Performance
Del Castillo began the 2025 season with the Triple-A Reno Aces after being optioned by the Arizona Diamondbacks in spring training. The assignment was viewed as a chance for him to refine his defensive consistency while continuing to refine his approach against high-level pitching. His early-season production in Reno was a focal point for both the major league staff and the team’s fan base.
Throughout the year, Del Castillo has remained on the short list of catchers the Diamondbacks consider when looking to add a right-handed power bat to their major league lineup.

With the Pacific Coast League MVP already on his résumé and a historic walk-off home run as his first major league hit, he has built meaningful momentum heading into the remainder of 2025 and beyond.
