Brett Harris Bio
Brett Steven Harris (born June 24, 1998) is an American professional baseball third baseman for the Athletics of Major League Baseball (MLB). A graduate of Gonzaga University, Harris entered professional baseball after being selected in the 2021 MLB Draft by the Oakland Athletics. He progressed steadily through the Athletics’ farm system before reaching the major leagues in 2024.
Known for his defensive reliability at the hot corner, Harris also drew attention during his college years as one of the top defensive infielders in the West Coast Conference. He has continued to develop his offensive game as he transitions to consistent major league playing time.
Early Life and Background
Brett Steven Harris was born on June 24, 1998, and grew up in the United States. He attended John Hersey High School in Arlington Heights, Illinois, where he played baseball and graduated in 2016. His time at John Hersey provided the foundation for his future in the sport, allowing him to refine the defensive skills that would later define his professional profile.
After completing high school, Harris enrolled at the University of Houston to play college baseball for the Houston Cougars. Although he did not appear in a game during his initial college experience, he used the opportunity to prepare for the next stage of his development. He then transferred to Central Arizona College, where he played during the 2018 season and continued to build his resume as a position player.
Seeking a stronger platform, Harris transferred to Gonzaga University, where he spent three years playing college baseball for the Gonzaga Bulldogs. His senior season in 2021 was particularly productive, as he batted .355 with six home runs, demonstrating both consistency and emerging power. That same year, he was recognized for his defensive work with the West Coast Conference Defensive Player of the Year award.
Path to Baseball
Harris’s path through the college ranks reflected patience and steady improvement. Following his transfer to Central Arizona College for the 2018 season, he adjusted to a higher level of competition and then made the jump to Gonzaga University, where he would spend his most formative college years. His performance in the West Coast Conference established him as one of the more polished infielders in the region.
During the summer of 2020, Harris played summer league baseball with the K-Town Bobbers of the Northwoods League, gaining additional experience against varied competition. The exposure helped him sharpen his game ahead of his senior season at Gonzaga, where his .355 batting average and six home runs made him an attractive prospect. The combination of offensive production and defensive excellence positioned him well for the upcoming MLB Draft.
In the 2021 Major League Baseball Draft, the Oakland Athletics selected Harris in the seventh round, marking the official start of his professional career. He signed with the organization and began working his way through the minor leagues, with the Athletics identifying him as a long-term third base option.
Brett Harris Career
Early Career (2021–2022)
After signing with the Oakland Athletics in 2021, Harris made his professional debut with the Arizona Complex League Athletics. He was promoted during the season to the Lansing Lugnuts, giving him his first taste of full-season minor league baseball. Over 27 games between the two affiliates, he batted .238 with three home runs, providing a glimpse of the power potential that would later emerge.
He opened the 2022 season with Lansing and earned a promotion to the Midland RockHounds in late May. The 2022 campaign proved to be a significant step forward, as Harris slashed .290/.374/.475 with 17 home runs, 63 RBIs, and 11 stolen bases over 113 games between the two teams. The performance signaled that his bat was catching up to his well-regarded defense, and he solidified his standing within the organization.
Minor League Advancement (2023)
Harris began the 2023 season with the Midland RockHounds and was promoted in mid-July to the Las Vegas Aviators, the Athletics’ Triple-A affiliate. The promotion reflected his continued growth and readiness for a higher level of competition. Over 105 games that season, he batted .279 with nine home runs and 62 RBIs, maintaining steady production as he climbed the ladder.
Following the regular season, Harris was selected to play in the Arizona Fall League with the Mesa Solar Sox, a traditional honor for top prospects in professional baseball. The opportunity allowed him to face some of the most advanced minor league talent in the game and further prepared him for a future major league role.
Las Vegas and Major League Debut (2024)
To open the 2024 season, Harris was assigned to the Las Vegas Aviators, where he continued to refine his approach at the plate. On May 3, 2024, he was promoted to the major leagues for the first time, fulfilling years of work through the minors. The call-up represented the next chapter in his career with the Oakland Athletics.
In his first major league action, Harris appeared in 36 games for the Athletics and hit .146 with three home runs and 12 RBIs. A standout moment came on May 4, when he recorded his first two major league hits and his first two home runs off of pitcher Darren McCaughan during a 20-4 win over the Miami Marlins. The performance offered a clear indication of the raw power he could provide at the highest level.
Current Team Era (2024–Present)
Harris opened the 2025 season on the injured list with an oblique injury and was subsequently optioned to the Las Vegas Aviators. The setback interrupted the momentum he had built during his rookie major league campaign, but the Athletics continued to view him as a developing piece of their long-term plans. His return to health and continued offensive growth were expected to shape his path back to Oakland.
Through the early portion of 2025, Harris worked to re-establish his timing in Triple-A while remaining a part of the Athletics’ third base depth chart. The combination of his prior major league experience and his track record in the minors positioned him as a candidate to contribute at the big league level once again.
