Alan Trejo Bio
Alan Ray Trejo, born on May 30, 1996, is an American professional baseball infielder. He has spent time in Major League Baseball (MLB) with the Colorado Rockies and has also played in the minor league systems of the Los Angeles Dodgers and Texas Rangers. Trejo was drafted by the Colorado Rockies in the 16th round of the 2017 MLB draft and made his major league debut with the club in 2021. He also represented Mexico in the 2023 World Baseball Classic.
Across his professional career, Trejo has built a profile as a versatile middle-infield prospect who worked his way through multiple levels of the minor leagues before reaching the majors. He has since moved between organizations as a depth infielder, contributing at the Triple-A level and occasionally appearing in the big leagues.
Early Life and Background
Alan Ray Trejo grew up in Southern California and developed his baseball skills in the Los Angeles area. He attended Cathedral High School in Los Angeles before transferring to Warren High School in Downey, California. Warren High School holds a special meaning in his family story, as his father works there as a math teacher.
After high school, Trejo enrolled at San Diego State University, where he played college baseball for the San Diego State Aztecs. His time with the Aztecs allowed him to face consistent high-level competition and helped him attract the attention of professional scouts.
His development at San Diego State, combined with his high school experience, positioned him as a draft-eligible prospect following his junior year. The Colorado Rockies selected Trejo in the 16th round of the 2017 Major League Baseball draft, launching his professional career.
Path to Baseball
Trejo began his climb through the Colorado Rockies organization shortly after being drafted. In 2017, he played for the rookie-level Grand Junction Rockies and put together an impressive first professional season, batting .347/.388/.566 with seven home runs and 32 runs batted in (RBI). That performance quickly established him as a prospect worth developing further.
He moved up to High-A Lancaster JetHawks in 2018, where he hit .278/.329/.425 with 10 home runs and a career-high 67 RBI. The following season, Trejo reached Double-A with the Hartford Yard Goats. In 125 games during 2019, he slashed .243/.290/.391 with 15 home runs and 39 RBI, showing his ability to handle the higher level of pitching.
The 2020 minor league season was canceled because of the COVID-19 pandemic, which kept Trejo off the field. He was added to the Rockies’ 60-man player pool that year and was invited to big league Spring Training in 2021. When he did not make the Opening Day roster, he began the year with the Triple-A Albuquerque Isotopes.
Alan Trejo Career
Early Career (2017–2020)
Trejo’s first full professional season came in 2017 with the Grand Junction Rockies, where he batted .347 with seven home runs and 32 RBI. His quick start suggested the Rockies had found a young infielder with offensive upside. The next year with Lancaster, he proved that his bat could play at a higher level, setting a personal best with 67 RBI.
His 2019 campaign at Hartford showed that he could handle the jump to Double-A, even as his batting average settled in at .243. The canceled 2020 season interrupted his momentum, but his inclusion in the Rockies’ 60-man player pool during the pandemic year kept him connected to the major league staff and prepared him for his eventual promotion.
Colorado Rockies Breakthrough (2021–2023)
Trejo received his first major league opportunity on April 10, 2021, when the Rockies selected his contract and added him to the 40-man roster. He debuted that same day as a pinch hitter in the ninth inning, flying out in his only at-bat. In 28 games during his rookie year, he hit .217/.260/.326 with one home run and three RBI.
In 2022, Trejo spent time between Albuquerque and Colorado. On June 28 of that year, he hit a walk-off grand slam off Jon Olczak of the Sugar Land Space Cowboys, helping Albuquerque win 11–9. The blast was the first walk-off grand slam in Isotopes history. In 35 games with the Rockies that season, he hit .271/.312/.424 with four home runs and 17 RBI.
The 2023 campaign marked his most extended look in the majors. Trejo appeared in 82 games for Colorado and hit .232/.288/.343 with four home runs and 26 RBI. He was outrighted to the minor leagues on January 5, 2024, and removed from the 40-man roster, opening the door for a series of moves across organizations.
Journeyman Years (2024–2025)
Trejo returned to the Rockies in 2024 after manager Bud Black announced on March 26 that his contract would be selected for the Opening Day roster. In 28 games with Colorado that year, he batted just .143/.182/.143 with one RBI. The Rockies designated him for assignment on June 28, and he elected free agency the following day.
On July 2, 2024, Trejo signed a minor league contract with the Los Angeles Dodgers and was assigned to the Triple-A Oklahoma City Baseball Club. He played 59 games for OKC, batting .265 with six home runs and 24 RBI. He elected free agency on November 4, 2024.
Trejo signed a minor league deal with the Texas Rangers on December 19, 2024. In 2025, he appeared in 19 games for the Triple-A Round Rock Express, batting .211/.247/.352 with 13 RBI and one stolen base. On April 26, 2025, he was traded back to the Colorado Rockies in exchange for cash considerations, and his contract was selected the next day. In 13 games for Colorado, he batted .175/.190/.225 with one RBI before being designated for assignment on May 16. He cleared waivers and elected free agency on May 18. Trejo returned to the Rangers on May 27, 2025, and produced his strongest Triple-A line of the year, hitting .261/.323/.466 with 14 home runs and 65 RBI in 93 games for Round Rock. He elected free agency again on November 6, 2025.

2025 Season Performance

In 13 games with Colorado, he struggled at the plate, batting .175 with one RBI before being designated for assignment in mid-May.
