Owen Miller Bio
Owen Robert Miller (born November 15, 1996) is an American professional baseball infielder and outfielder. He has played in Major League Baseball (MLB) for the Cleveland Indians / Guardians, Milwaukee Brewers, and Colorado Rockies. Miller was selected by the San Diego Padres in the third round of the 2018 MLB draft and made his MLB debut in 2021 with the Indians. A versatile player capable of handling multiple positions, he has moved between clubs through trades and minor league contracts throughout his career.
Born and raised in the upper Midwest, Miller developed as a multi-sport athlete before focusing on baseball and working his way through college and the minor leagues. Over the course of his professional career he has been used at first base, second base, third base, and in the outfield, providing the kind of positional flexibility that has helped him remain in affiliated baseball.
Early Life and Background
Owen Robert Miller grew up in Fredonia, Wisconsin, where he attended Ozaukee High School. During his four years at Ozaukee, he played football and basketball while also taking part in baseball. After his freshman year, he stepped away from the high school baseball program to focus on travel baseball, a decision that gave him more games against top competition and helped shape his offensive profile as a contact-oriented hitter with emerging power.
Following his high school graduation, Miller was not selected in the 2015 MLB draft, which pushed him toward the college route. He enrolled at Illinois State University and joined the Illinois State Redbirds baseball program, where he became an immediate contributor. The combination of Wisconsin roots, multi-sport athletic background, and a strong college resume at Illinois State set the foundation for his professional career.
Path to Professional Baseball
At Illinois State University, Miller played college baseball for the Redbirds across three seasons. As a freshman in 2016, he started all 54 games and hit .328 with five home runs and 44 runs batted in, establishing himself as one of the conference’s top young hitters. His strong start earned him consistent playing time and positioned him for an even bigger sophomore campaign.
In 2017, Miller slashed .325/.351/.498 with six home runs and 48 runs batted in over 56 games, earning All-Missouri Valley Conference Second-Team honors. That summer he played collegiate baseball with the Harwich Mariners of the Cape Cod Baseball League and also appeared in the Northwoods League, gaining exposure against elite amateur competition. As a junior in 2018, he batted .384 with six home runs and 35 runs batted in across 52 games and was named All-MVC First-Team, cementing his status as a draft prospect.

The San Diego Padres selected Owen Robert Miller in the third round, 84th overall, of the 2018 MLB draft, and he signed with the club for $500,000. He made his professional debut that summer with the Tri-City Dust Devils of the Low-A Northwest League, where he was named an All-Star. Promoted in August to the Fort Wayne TinCaps of the Single-A Midwest League, he combined to slash .336/.386/.460 with four home runs and 33 runs batted in across 75 games between the two clubs.

Cleveland Indians / Guardians Era (2020–2022)
On August 31, 2020, Owen Robert Miller was part of a major multiplayer trade that sent him, along with Austin Hedges, Cal Quantrill, Josh Naylor, Gabriel Arias, and Joey Cantillo, to the Cleveland Indians in exchange for Mike Clevinger, Greg Allen, and Matt Waldron. He did not appear in a minor league game in 2020 after the minor league season was canceled because of the COVID-19 pandemic. To begin the 2021 season he was assigned to the Columbus Clippers of Triple-A East, where he batted .406 with two home runs and nine runs batted in across 16 games before getting the call to the majors.
On May 23, 2021, Miller was added to the Indians’ 40-man roster and promoted to the major leagues for the first time. He debuted the same day as the designated hitter against the Minnesota Twins, going hitless in five at-bats with three strikeouts, and recorded his first major league hit, an infield single, on May 24 versus Spencer Turnbull of the Detroit Tigers. On July 31, he hit his first career home run off Dallas Keuchel of the Chicago White Sox. Across 60 games for the 2021 Indians, he batted .204 with four home runs and 18 runs batted in.
In 2022, Miller batted .243/.301/.351 and posted the fastest sprint speed of all major league first basemen at 29.0 feet per second, highlighting his athleticism around the bag. His combination of positional versatility and foot speed made him a useful piece for Cleveland even as the franchise transitioned from the Indians name to the Guardians.
Milwaukee Brewers Era (2022–2024)
On December 14, 2022, Owen Robert Miller was traded to the Milwaukee Brewers in exchange for a player to be named later and an unspecified amount of cash.

His blend of contact hitting, plate discipline, and speed fit well with the Brewers’ style of play, and he saw time at multiple positions across the diamond.
Miller was optioned to the Triple-A Nashville Sounds to begin the 2024 season and was recalled on April 16 following an injury to Christian Yelich. In 14 games with Milwaukee that year he went 5-for-27 with a .185 average and three runs batted in. On July 1 the Brewers designated him for assignment, and after clearing waivers he was sent outright to Nashville on July 5, ending his major league time in Milwaukee for that season.

In nine appearances for Colorado he went 2-for-14 with a .143 average, one run batted in, one stolen base, and two walks before being designated for assignment on May 16.
Miller cleared waivers and elected free agency on May 20, then re-signed with the Rockies on a minor league contract on May 28 to remain in the organization. After the season he again elected free agency on November 6, opening the door to his next opportunity in affiliated baseball.
Chicago Cubs Era (2026–Present)

The deal gave him a fresh pathway back to the big leagues through one of the most storied franchises in the National League.
Driving Style and Strengths
Miller is valued primarily for his contact-oriented left-handed swing, his willingness to use the whole field, and his above-average speed on the basepaths. Defensively he has logged significant innings at first base, second base, third base, and the outfield, with his 29.0 feet-per-second sprint speed as a first baseman in 2022 standing out as a rare athletic marker for the position. That mix of offensive discipline, defensive flexibility, and baserunning instinct has defined his role on every club he has joined.

Beyond his connection to his brother, Miller keeps much of his personal life private, and public details about his relationships, residence, or activities outside of baseball are limited.
