Early Life and Background
Owen Robert Miller was raised in Wisconsin and attended Ozaukee High School in Fredonia, where he played football and basketball all four years and focused on travel baseball after his freshman season. He went undrafted out of high school in 2015 and enrolled at Illinois State University, where he played college baseball for the Illinois State Redbirds.
At Illinois State, Miller started immediately and established himself as a consistent contact hitter. As a freshman he started all 54 games and hit .328, and he earned All-Missouri Valley Conference honors later in his college career, including All-MVC First-Team recognition as a junior in 2018.
Path to Baseball
Miller developed through collegiate summer leagues and the minor leagues on his path to the majors.

He signed and began his professional career that same year.

Early Career (2018–2019)
Miller signed with the San Diego Padres after the 2018 draft and made an immediate impression at Low-A and Single-A, hitting .336 across Tri-City and Fort Wayne in his first professional season and being named an All-Star. In 2019 he spent the full season with the Amarillo Sod Poodles at Double-A, where he slashed .290/.355/.430 with 13 home runs and 68 RBIs over 130 games and earned Texas League All-Star honors.
The 2020 minor league season was cancelled due to the COVID-19 pandemic, and Miller did not play in organized minor league games that year. He was part of a multi-player trade in August 2020 that sent him from the San Diego Padres to the Cleveland Indians as part of a package for Mike Clevinger and others.
Cleveland Indians / Guardians Breakthrough (2021–2022)
Miller began the 2021 season at Triple-A Columbus and hit well enough to earn a promotion. On May 23, 2021, he was selected to Cleveland’s 40-man roster and made his major league debut the same day as the designated hitter. He recorded his first major league hit on May 24, 2021, and hit his first big league home run on July 31, 2021.
Across the 2021 season Miller appeared in sixty games for Cleveland, batting .204 with four home runs and 18 RBIs. In 2022 he appeared in the major league roster again and finished the season batting .243/.301/.351; Statcast data recorded him as the fastest sprinting first baseman in MLB that year, with a top sprint speed mark reported for that position.
Milwaukee Brewers Breakthrough (2023–2024)
On December 14, 2022, Miller was traded to the Milwaukee Brewers. In 2023 he appeared in 90 games for Milwaukee and posted a .261/.303/.371 line with five home runs, 27 RBIs, and 13 stolen bases, contributing on both defense and the bases. The Brewers optioned Miller to Triple-A Nashville to begin 2024, and he was recalled in April following an injury to a teammate.
Miller saw limited big league action in 2024, appearing in 14 games and going 5-for-27 with three RBIs before being designated for assignment on July 1. He cleared waivers and was outrighted to Nashville, finishing the season in the Brewers organization before later being traded.
Colorado Rockies Era (2025)
On November 2, 2024, the Milwaukee Brewers traded Miller to the Colorado Rockies for cash considerations. He was assigned to the Triple-A Albuquerque Isotopes to begin the 2025 season and had his contract selected by the Rockies on April 25, 2025, joining their active roster.
In nine appearances for Colorado he went 2-for-14 (.143) with one RBI, one stolen base, and two walks. The Rockies designated him for assignment on May 16, 2025; he cleared waivers, elected free agency on May 20, re-signed to a minor league contract on May 28, and elected free agency again following the 2025 season on November 6.
Driving Style and Strengths
Miller is valued for his versatility across the infield and outfield, his contact-oriented left-handed bat, and above-average speed. Scouts and team reports highlight his baserunning instincts and defensive range, which have allowed him to contribute in multiple roles as a utility player and late-inning substitute.
Notable Events and Milestones
Key moments in Miller’s career include his third-round selection in the 2018 MLB draft, his 2021 major league debut and first big league home run, a full Double-A All-Star season in 2019, and his 2023 season in Milwaukee where he added speed and multi-positional value to a major league roster.
