Standing out as a steady middle-infield option throughout his professional career, Trejo has built a reputation for solid defense and timely hitting in the minor leagues. His career has carried him across several organizations, and he suited up for the Mexico national team during the 2023 World Baseball Classic.
Early Life and Background
Alan Ray Trejo was born on May 30, 1996, and grew up in the Los Angeles area of Southern California. He attended Cathedral High School in Los Angeles before transferring to Warren High School in Downey, California, where he continued to develop as a young baseball player. The move to Warren connected him to a familiar environment, as his father works as a math teacher at the school.
Coming from an academic and athletic family, Trejo balanced his education with a growing passion for the game. His time at Warren High School allowed him to refine his infield skills and showcase the tools that would eventually attract professional scouts. The Southern California baseball scene, known for producing polished position players, helped shape his early development.
After completing high school, Trejo enrolled at San Diego State University, where he played college baseball for the San Diego State Aztecs. His performance in the collegiate ranks caught the attention of Major League scouts and set the stage for his entry into professional baseball.
Path to Baseball
Trejo’s path to professional baseball ran straight through the San Diego State Aztecs program. Playing in a competitive conference, he continued to improve his offensive game while demonstrating the defensive versatility that has defined his career. Scouts valued his glove work, and his bat gradually developed as he faced top-level college pitching.
In 2017, the Colorado Rockies selected Trejo in the 16th round of the Major League Baseball draft. Although he was not an early-round selection, his skill set gave the Rockies a projectable middle-infield prospect. He signed with the organization and began his climb through the minor leagues that same year, starting at the rookie level.

The strong start signaled that his bat could play against younger competition.
In 2018, Trejo advanced to the High-A Lancaster JetHawks, where he hit .278 with a .329 on-base percentage and a .425 slugging percentage. He added 10 home runs and set a career high with 67 runs batted in.

Colorado Rockies Breakthrough (2021–2023)
