Oliver Dunn Bio
Oliver Harris Dunn, born on September 2, 1997, is an American professional baseball infielder who is currently in the Chicago White Sox organization. He has previously played in Major League Baseball (MLB) for the Milwaukee Brewers. A graduate of the University of Utah, Dunn was originally drafted by the New York Yankees in 2019 and has steadily climbed through the minor league system before reaching the major leagues.
Early Life and Background
Oliver Harris Dunn grew up in the Salt Lake City area of Utah and attended Cottonwood High School in nearby Murray. At Cottonwood, he developed into a promising infielder and drew attention from college programs across the region. His combination of contact skills, on-base ability, and versatility at the plate helped establish him as a legitimate prospect heading into his college years.
After high school, Dunn enrolled at the University of Utah, where he played college baseball for the Utah Utes. He continued to refine his offensive approach and defensive fundamentals during his time in Salt Lake City, working with the Utes’ coaching staff to prepare for a professional career. Following his junior season, Dunn declared for the MLB draft, confident in his development as a position player.
Dunn also gained valuable experience during the summer of 2018 when he played collegiate summer baseball with the Wareham Gatemen of the Cape Cod Baseball League. The Cape Cod League is widely regarded as one of the premier amateur baseball leagues in the country, and his time with the Gatemen helped expose him to high-level competition. That summer experience played a key role in his readiness for professional baseball.
Path to Baseball
Dunn’s path to professional baseball began in earnest when the New York Yankees selected him in the 11th round of the 2019 Major League Baseball draft, with the 345th overall pick. He split his first professional season between the rookie-level Pulaski Yankees and the Single-A Charleston RiverDogs, getting his first taste of the minor leagues. The following year, however, he did not appear in any games because the minor league season was canceled due to the COVID-19 pandemic.
Dunn returned to action in 2021, playing for the High-A Hudson Valley Renegades and Double-A Somerset Patriots. In 72 games between the two affiliates, he batted .196/.335/.368 with seven home runs, 25 runs batted in, and 10 stolen bases. The following season, he moved between Somerset and the Triple-A Scranton/Wilkes-Barre RailRiders, posting a strong .288/.406/.525 line with three home runs and 18 runs batted in across 36 games, signaling his growth as a hitter at higher levels.
Oliver Dunn Career
Early Career (2019–2022)
Dunn began his professional career in 2019 as an 11th-round selection by the New York Yankees, splitting time between Pulaski and Charleston. After the canceled 2020 season, he returned in 2021 and showed plate discipline and speed across Hudson Valley and Somerset. His 2022 campaign at Double-A and Triple-A levels demonstrated a clearer offensive identity, with improved extra-base production.
On December 7, 2022, the Philadelphia Phillies selected Dunn in the minor league phase of the Rule 5 draft, bringing him into a new organization. He spent the entire 2023 season with the Double-A Reading Fightin Phils and produced career-highs across the board, batting .271/.396/.506 with 21 home runs, 78 runs batted in, and 16 stolen bases. Following the regular season, he also participated in the Arizona Fall League to continue his development.
Milwaukee Brewers (2023–2025)
On November 14, 2023, the Philadelphia Phillies traded Dunn to the Milwaukee Brewers in exchange for Hendry Mendez and Robert Moore. The Brewers subsequently added him to their 40-man roster to protect him from the Rule 5 draft. This marked a significant step toward a potential major league opportunity.
Dunn was optioned to the Triple-A Nashville Sounds to begin the 2024 season. However, an injury to Garrett Mitchell created an opening, and Dunn was recalled to the Brewers’ Opening Day roster. In 41 games with Milwaukee, he batted .221/.282/.316 with one home run, seven runs batted in, and three stolen bases. On June 27, he was placed on the injured list with a back strain and was later transferred to the 60-day injured list on July 15.
Heading into 2025, Dunn competed for playing time at third base for the Brewers. After batting .167 in his first 41 plate appearances of the season, the Brewers optioned him back to Nashville. He was designated for assignment on August 30, cleared waivers, and was sent outright to Triple-A Nashville on September 1. Dunn elected free agency on November 6, 2025, ending his time with Milwaukee.
Chicago White Sox (2025–Present)
On December 14, 2025, Oliver Harris Dunn signed a minor league contract with the Chicago White Sox, joining a new organization as he continues his professional career. The move gives him an opportunity to compete for a major league roster spot within the White Sox system. His experience across multiple minor league levels and his prior major league time with Milwaukee make him a veteran presence within the organization.
Notable Events and Milestones
One of the defining moments of Dunn’s career came with his MLB debut for the Milwaukee Brewers in 2024, a milestone reached after years of climbing through the Yankees, Phillies, and Brewers minor league systems. His 2023 season at Double-A Reading stands out statistically, with career-high totals of 21 home runs, 78 runs batted in, and 16 stolen bases that signaled his all-around offensive growth. Being added to the Brewers’ 40-man roster in 2023 also marked a significant organizational milestone, protecting him from the Rule 5 draft.

2025 Season Performance
Oliver Harris Dunn’s 2025 season was defined by his competition for the third base role with the Milwaukee Brewers. After beginning the year on the major league roster, he struggled offensively in his first 41 plate appearances, batting just .167. That slow start led to his option back to the Triple-A Nashville Sounds, where he looked to rediscover his rhythm at the plate.
On August 30, the Brewers designated Dunn for assignment, and he cleared waivers before being sent outright to Nashville on September 1. He elected free agency on November 6, 2025, bringing his time in the Milwaukee organization to a close. Shortly afterward, on December 14, 2025, he signed a minor league contract with the Chicago White Sox, opening a new chapter in his career and giving him a fresh opportunity to earn a major league role.
