Alex Carrillo Bio
Alejandro Carrillo, known professionally as Alex Carrillo, is an American professional baseball pitcher currently in the New York Mets organization of Major League Baseball (MLB). Born on June 6, 1997, in West Covina, California, Carrillo signed with the Mets on November 14, 2024, and reached the majors for the first time during the 2025 season. His road to the big leagues wound through independent baseball and the Mexican League, a path that reflects his resilience and willingness to keep pitching whenever an opportunity appeared.
Carrillo works as a right-handed reliever and wears number 84 with the Mets. Through the 2025 season, his MLB line includes a 0–1 win–loss record, a 13.50 earned run average, and four strikeouts across a small sample of major league innings. Despite those modest numbers, his debut marked a significant personal milestone after several years spent navigating the uncertainty of professional baseball outside the affiliated system.
Early Life and Background
Alejandro Carrillo grew up in West Covina, California, a suburban community in the eastern San Gabriel Valley. Like many Southern California kids, he came of age around year-round baseball, sharpening his game on local diamonds and high school fields. West Covina’s deep baseball culture, with travel ball, American Legion programs, and showcase circuits running throughout the year, gave him a steady stream of competition.
After finishing high school, Carrillo took his career to the next level at Faulkner University, a private school in Montgomery, Alabama, that competes in NAIA athletics. Playing for the Faulkner Eagles allowed him to face older and more experienced hitters while continuing to develop his craft on the mound. The college years gave him the platform he needed to attract professional interest, even as an undrafted prospect coming out of a smaller program.
Path to Professional Baseball
Following 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 that summer with the rookie-level Arizona League Rangers, striking out six batters across three scoreless appearances and giving the Rangers a glimpse of his bullpen potential. The momentum he built, however, was put on hold when the 2020 minor league season was cancelled because of the COVID-19 pandemic, and he was released by the Rangers organization on June 1, 2020.
Rather than step away from the game, Carrillo kept grinding. On June 29, 2020, he signed with the Pericos de Puebla of the Mexican League, although that season was also cancelled due to the pandemic. He then moved into independent baseball in January 2021, joining the New York Boulders for their inaugural Frontier League season. In 14 appearances with the Boulders, Carrillo posted a 7.11 ERA with 15 strikeouts over 19 innings, gaining valuable innings and learning to handle the irregular schedule that defines independent ball.
Alex Carrillo Career
Early Career (2019–2021)
Carrillo’s earliest professional chapter was brief but encouraging. With the Arizona League Rangers in 2019, he showed the swing-and-miss stuff that had marked his college career, fanning six hitters without allowing a run in his first three outings. That summer hinted at a future in the bullpen, but the cancelled 2020 season interrupted his momentum, and his release from the Rangers organization forced him to find a new home.
Independent baseball became that home. With the New York Boulders in 2021, Carrillo logged 14 relief appearances and 19 innings, posting a 7.11 ERA while striking out 15 batters. The numbers were uneven, but the experience was essential, as he proved he could handle the travel demands of the Frontier League and remain ready whenever his number was called.
Mexican League Years (2022–2023)
On April 21, 2022, Carrillo moved south to join the Tigres de Quintana Roo of the Mexican League, a major step up in competition and visibility. In 21 appearances during his first season with Quintana Roo, he went 1–2 with an 8.49 ERA while striking out 40 batters across 29⅔ innings. His strikeout rate showed the raw arsenal remained, even as the results fluctuated against veteran international lineups.
Carrillo returned to Quintana Roo for the 2023 campaign and again worked out of the bullpen, making 22 appearances. He registered a 1–0 record, an 8.06 ERA, 29 strikeouts, and one save over 22⅓ innings. The saves and continued strikeout totals underscored his late-inning potential, and his time in Mexico gave him the volume he needed to stay sharp.
Washington Wild Things and Mets Breakthrough (2024–2025)
On April 1, 2024, Carrillo signed with the Washington Wild Things of the Frontier League, where his career took a sharp upward turn. In 35 relief appearances for Washington, he put together a 3–1 record and a 3.31 ERA, striking out 49 batters and adding one save across 35⅓ innings. Those numbers marked the best stretch of his professional career and drew renewed attention from affiliated baseball.
That attention translated into an opportunity on November 14, 2024, when Carrillo signed a minor league contract with the New York Mets organization. He opened 2025 with the Double-A Binghamton Rumble Ponies, going 2–1 with a 4.19 ERA and 30 strikeouts in 15 appearances. After a promotion to the Triple-A Syracuse Mets on June 22, 2025, four scoreless outings convinced the organization to bring him to the majors. On July 8, 2025, Carrillo was formally selected to the Mets’ 40-man and active rosters. In his MLB debut against the Baltimore Orioles at Camden Yards, he pitched 1⅓ innings and surrendered a home run to Jackson Holliday during a Mets 7–6 comeback win in 10 innings. Across three appearances in his rookie campaign, Carrillo finished with an 0–1 record, a 13.50 ERA, and four strikeouts over 4⅔ innings. He was optioned to Triple-A Syracuse to begin the 2026 season.
Driving Style and Strengths
Carrillo is best deployed as a late-inning reliever, with his highest leverage work coming in shorter bursts. His calling card has always been the strikeout: across his stints in the Mexican League and the Frontier League, he regularly punched out more than a batter per inning. He relies on attacking hitters and avoiding long plate appearances, a style that suits the high-leverage middle relief and setup roles he has filled throughout his career.
Notable Events and Milestones
Carrillo’s most memorable moment came on July 8, 2025, when he made his MLB debut at Camden Yards against the Baltimore Orioles. His first major league appearance included a showdown with Jackson Holliday, one of the sport’s top young hitters, in a game the Mets eventually won in 10 innings. Signing with the New York Mets in November 2024 and reaching the majors less than a year later also stands as a signature milestone in a career built on second chances.

2025 Season Performance
Alex Carrillo’s 2025 season told the story of a pitcher finally getting his shot. He opened the year with the Double-A Binghamton Rumble Ponies, recording a 2–1 record and a 4.19 ERA with 30 strikeouts in 15 appearances.
