Alex Carrillo Bio
Alejandro Carrillo, known professionally as Alex Carrillo, is an American professional baseball pitcher who currently plays for the New York Mets of Major League Baseball (MLB). He made his MLB debut in 2025 after a long and winding journey through independent and international baseball leagues. Born in West Covina, California, Carrillo attended Faulkner University and began his professional career as an undrafted free agent in 2019. His path to the majors reflects resilience and determination, as he moved through multiple organizations in the United States and Mexico before earning his first call-up to the big leagues.
Standing as a left-handed relief pitcher, Carrillo carved out his place in professional baseball by adapting to varied competition levels. Before reaching MLB, his career included stints with the Texas Rangers organization, the New York Boulders of the Frontier League, the Tigres de Quintana Roo of the Mexican League, and the Washington Wild Things. His promotion to the Mets in 2025 marked the culmination of years spent refining his craft in the minor leagues and independent baseball circuits.
Early Life and Background
Alejandro Carrillo was born on June 6, 1997, in West Covina, California. Growing up in Southern California, he was exposed to a vibrant baseball culture that produced many major leaguers. West Covina and the surrounding San Gabriel Valley area have long been recognized for developing competitive baseball talent, and Carrillo developed his game in that environment before pursuing collegiate opportunities.
He attended Faulkner University in Montgomery, Alabama, where he continued to develop as a pitcher. Although he was not selected in the MLB Draft following his college career, his performance at Faulkner caught the attention of professional scouts, leading to an opportunity to sign as an undrafted free agent. His decision to attend Faulkner and his development there were foundational steps that prepared him for the rigors of professional baseball.
Path to Professional Baseball
After his time at Faulkner University, Carrillo signed with the Texas Rangers organization as an undrafted free agent on August 16, 2019. He made his professional debut with the rookie-level Arizona League Rangers, where he struck out six batters across three scoreless relief appearances. The performance offered an early glimpse of the strikeout ability that would become a hallmark of his career.
The 2020 season posed significant challenges across all of professional baseball due to the COVID-19 pandemic, and Carrillo did not appear in a game that year. The minor league season was cancelled, and he was ultimately released by the Rangers organization on June 1, 2020. Despite the setback, Carrillo quickly pursued new opportunities, signing briefly with the Pericos de Puebla of the Mexican League, though the season there was also cancelled.
Alex Carrillo Career
Early Career (2019-2021)
Carrillo’s first professional experience came in the Arizona League in 2019 with the Rangers organization, where he impressed with his ability to miss bats. After the 2020 season was wiped out by the pandemic and his release from the Rangers, he pivoted to independent baseball. On January 21, 2021, he signed with the New York Boulders for their inaugural season in the Frontier League. In 14 appearances for the Boulders, he recorded a 7.11 ERA with 15 strikeouts across 19 innings, gaining valuable experience in a new competitive environment.
The 2021 season represented a critical development year for Carrillo as he adjusted to the demands of independent professional baseball. Despite the high ERA, the innings and the exposure to veteran hitters helped him continue his growth as a relief pitcher. His willingness to compete in the Frontier League rather than step away from the game demonstrated the persistence that would eventually carry him back to affiliated baseball.
Tigres de Quintana Roo Era (2022-2023)
On April 21, 2022, Carrillo signed with the Tigres de Quintana Roo of the Mexican League, marking his return to a high-level professional league. In 21 appearances that year, he struggled to a 1-2 record and an 8.49 ERA, but he also recorded 40 strikeouts across 29 and two-thirds innings, reinforcing his reputation as a strikeout pitcher. The Mexican League provided a challenging environment that tested his mental and physical toughness.
Carrillo returned to Quintana Roo in 2023 and again served as a key member of their bullpen. He made 22 appearances out of the bullpen, registering a 1-0 record and an 8.06 ERA with 29 strikeouts and one save across 22 and one-third innings of work. The experience in Mexico helped him refine his approach against experienced hitters and prepared him for his eventual return to the affiliated ranks.
Washington Wild Things Era (2024)
On April 1, 2024, Carrillo signed with the Washington Wild Things of the Frontier League, beginning what would become his most successful independent league season. In 35 relief appearances for the Wild Things, he compiled a 3-1 record and a 3.31 ERA with 49 strikeouts and one save across 35 and one-third innings pitched. The dramatic improvement in his ERA reflected his growth as a pitcher and caught the attention of Major League organizations.
His performance with Washington positioned him for an opportunity back in affiliated baseball. The combination of his strikeout totals, improved command, and consistency out of the bullpen made him an attractive target for teams seeking depth in their minor league systems. The 2024 season proved to be the turning point in his career.
New York Mets Era (2024-Present)
On November 14, 2024, Carrillo signed a minor league contract with the New York Mets organization, marking his return to Major League Baseball’s affiliated system. He began the 2025 season with the Double-A Binghamton Rumble Ponies, where he logged a 2-1 record and a 4.19 ERA with 30 strikeouts over 15 appearances. His strong performance at Double-A quickly earned him a promotion to the Triple-A Syracuse Mets on June 22, 2025.
After four scoreless appearances for Syracuse, the Mets announced on July 8, 2025, that Carrillo would be promoted to the major leagues for the first time. He was formally selected to the team’s 40-man and active rosters later that day. In his MLB debut, Carrillo pitched one and one-third innings and gave up a home run to Jackson Holliday in the Mets’ comeback 7-6 win in 10 innings over the Baltimore Orioles at Camden Yards. The debut marked the realization of a long-held dream and the reward for years of perseverance across multiple leagues.

His journey through the Frontier League and the Mexican League, paired with his return to affiliated baseball via a minor league contract, made his promotion one of the more notable stories of the Mets’ 2025 season.
