He has previously played in Major League Baseball (MLB) for the San Diego Padres and Pittsburgh Pirates, and he is also an alumnus of the University of the Pacific.

Early Life and Background
Brett Charles Sullivan was born on February 22, 1994, in Stockton, California. He grew up in the same Central Valley city where he would later become a notable amateur prospect, and his family life was closely tied to athletics. His older brother, Tyler, played baseball alongside Brett at both Lincoln High School and the University of the Pacific.
Sullivan attended Lincoln High School in Stockton, where he developed into a multi-sport athlete and earned recognition as a promising catching prospect. After graduating, he continued his baseball career at the University of the Pacific, playing college baseball for the Pacific Tigers. His time at the collegiate level allowed him to refine his skills behind the plate while facing higher-level competition.
Path to Professional Baseball
Following his freshman year at the University of the Pacific, Sullivan spent the summer of 2014 playing collegiate summer baseball with the Bourne Braves of the Cape Cod Baseball League, one of the premier amateur leagues in the United States. That summer experience exposed him to elite competition and helped sharpen his game against top amateur talent.
The Tampa Bay Rays selected Sullivan in the 17th round, with the 508th overall pick, of the 2015 MLB Draft, officially launching his professional career. He signed with the organization and began climbing the minor-league ladder, splitting time between catching duties and contributing offensively at each level he reached.
Brett Sullivan Career
Early Career (2015-2017)
Sullivan opened his professional career in 2015 with the rookie-level Princeton Rays, appearing in 65 games during his first season. In 2016, he advanced to Single-A with the Bowling Green Hot Rods, where he posted a .283/.314/.438 slash line with 13 home runs, 81 runs batted in, and 17 stolen bases across 118 games. Those numbers signaled his combination of gap power, run-producing ability, and surprising speed for a catcher.
The 2017 season saw Sullivan split the year between the High-A Charlotte Stone Crabs and the Double-A Montgomery Biscuits. Across both levels, he hit a cumulative .294/.324/.433 with 8 home runs, 74 RBI, and 18 stolen bases in 107 games, demonstrating that he could handle the jump to more advanced pitching while continuing to contribute on the base paths.
Tampa Bay Rays Organization (2018-2021)
Sullivan spent the bulk of the 2018 season at Montgomery, playing 111 games and batting .266/.322/.380 with 7 home runs, 65 RBI, and 17 stolen bases. He returned to Montgomery for a third consecutive year in 2019, and on June 6 of that season he hit for the cycle against the Tennessee Smokies, one of the signature individual achievements of his minor-league career. He finished 2019 with 102 games played, hitting .280/.333/.459 with 10 home runs, 51 RBI, and a career-high 21 stolen bases.
The 2020 minor-league season was canceled because of the COVID-19 pandemic, costing Sullivan a year of development. He returned in 2021 with the Triple-A Durham Bulls, batting .223/.302/.375 with 9 home runs, 35 RBI, and 7 stolen bases in 90 games. He elected free agency on November 7, 2021, ending his time in the Rays organization.
Milwaukee Brewers and San Diego Padres (2022-2024)
On December 1, 2021, Sullivan signed a major-league deal with the Milwaukee Brewers. Less than five months later, on April 6, 2022, the Brewers traded him, along with Korry Howell, to the San Diego Padres in exchange for Víctor Caratini. He spent the rest of 2022 with the Triple-A El Paso Chihuahuas, hitting .285/.339/.444 with 9 home runs and a career-high-tying 81 RBI in 113 games.
Sullivan began 2023 back at El Paso but was promoted to the majors on April 16, 2023, after Luis Campusano suffered a left thumb sprain. He made his MLB debut two days later on April 18, starting as the catcher against the Atlanta Braves. In 33 games during his rookie MLB season, Sullivan batted .210/.244/.284 with one home run and six RBI. He returned to El Paso to open 2024, was recalled on April 16, and went 3-for-16 with one home run and two RBI in seven games before being designated for assignment by the Padres on March 22, 2025, and sent outright to Triple-A El Paso after clearing waivers.
Pittsburgh Pirates (2025)
On April 16, 2025, the San Diego Padres traded Sullivan to the Pittsburgh Pirates in exchange for Bryce Johnson. He joined the Triple-A Indianapolis Indians and batted .211/.250/.324 with one home run, 10 RBI, and two stolen bases in 20 appearances. On June 7, 2025, Pittsburgh selected his contract after catcher Endy Rodríguez went on the injured list, giving him another opportunity at the major-league level.
Sullivan appeared in three games for the Pirates, going 1-for-6 with two RBI and one walk. He was designated for assignment on June 16, cleared waivers, and elected free agency on June 19 before re-signing with Pittsburgh on a minor-league contract the next day. He elected free agency again at season’s end on November 6.
Colorado Rockies Era (2026-Present)
On December 18, 2025, Sullivan signed a minor-league contract with the Colorado Rockies. On March 25, 2026, the Rockies selected his contract after he made the team’s Opening Day roster, securing his spot on an MLB roster to open the season.
Through the early portion of the 2026 campaign, Sullivan has appeared in games for Colorado, batting .208 with 6 home runs and 23 RBI as of June 21, 2026. His power production has been a noticeable addition to a Rockies lineup, even as his average has fluctuated.
