Codi Dalton Heuer Bio
Codi Dalton Heuer is an American professional baseball pitcher who currently plays for the Cleveland Guardians organization in Major League Baseball. Born on July 3, 1996, in Missoula, Montana, Heuer has built a career spanning multiple MLB franchises including the Chicago White Sox, Chicago Cubs, Texas Rangers, and Detroit Tigers. Heuer emerged as a promising relief pitcher after being drafted by the Chicago White Sox in 2018, eventually establishing himself at the major league level with a career win-loss record of 10-5 and an earned run average of 3.82 through June 2026.
Early Life and Background
Heuer was born and raised in Missoula, Montana, where his early childhood took place. Before beginning high school, his family relocated to Fort Collins, Colorado. This move would prove significant as Heuer attended Fossil Ridge High School in Fort Collins, a school that would become notable in his baseball development. During his senior year at Fossil Ridge in 2015, Heuer delivered a standout performance that set a school record when he threw a complete game shutout while striking out 17 batters. This dominant display showcased the talent that would eventually carry him to professional baseball.
Despite his impressive high school performance, Heuer went undrafted in the 2015 Major League Baseball draft. Rather than pursuing other opportunities, he chose to continue his baseball career at the collegiate level by enrolling at Wichita State University, where he played for the Shockers baseball program. This decision to develop his skills at the college level would prove instrumental in his eventual path to professional baseball.
Path to Professional Baseball
Heuer spent three seasons playing college baseball for Wichita State University from 2016 to 2018. During his freshman year in 2016, he appeared in 21 games, making two starts, and posted a 1-1 record with a 9.12 earned run average over 24 and two-thirds innings. As a sophomore in 2017, Heuer improved to a 2-2 record with a 4.42 earned run average across 38 and two-thirds innings pitched.
His junior season in 2018 represented a breakthrough, as Heuer became Wichita State’s Friday night starter. He compiled a 6-5 record with a 4.31 earned run average over 16 appearances, making 15 starts. This strong performance caught the attention of professional scouts, leading to Heuer being selected by the Chicago White Sox in the sixth round of the 2018 Major League Baseball draft. The selection marked his official entry into professional baseball, launching a career that would span multiple organizations.
Codi Dalton Heuer Career
Minor League Development (2018–2019)
After signing with the Chicago White Sox following the 2018 draft, Heuer began his professional career with the Great Falls Voyagers in the Pioneer League. He made 14 starts during his debut season, going 0-1 with a 4.74 earned run average over 38 innings. Despite his individual record, the Voyagers won the Pioneer League championship, giving Heuer early experience with a winning culture at the professional level.
The 2019 season brought a significant transition as Heuer moved from starting to relief pitching. He began the year with the Winston-Salem Dash and earned a promotion to the Birmingham Barons in June. Over 42 combined relief appearances between both teams, Heuer demonstrated his effectiveness as a reliever by going 6-4 with an impressive 2.39 earned run average while recording 65 strikeouts over 67 and two-thirds innings. This strong performance positioned him for an opportunity at the major league level.
Chicago White Sox Breakthrough (2020–2021)
On July 23, 2020, Heuer received notification that he had been named to the Chicago White Sox Opening Day roster, a significant milestone in his career. He made his Major League Baseball debut the following night against the Minnesota Twins, recording one strikeout while pitching a scoreless inning. The 2020 season proved to be an excellent introduction to major league competition, as Heuer appeared in 21 games and compiled a 3-0 record with a 1.52 earned run average and 25 strikeouts across 23 and two-thirds innings pitched. His performance helped the White Sox remain competitive during the shortened season.
The 2021 season saw Heuer continue his role in the White Sox bullpen, though his numbers showed some regression. Over 38 and two-thirds innings pitched across 40 appearances, he went 4-1 with a 5.12 earned run average and 39 strikeouts. The White Sox remained in contention throughout the season, and Heuer remained a part of their late-inning relief corps before his season took an unexpected turn.
Chicago Cubs Era (2021–2022)
On July 30, 2021, Heuer’s tenure with the White Sox ended when he was traded to the Chicago Cubs along with Nick Madrigal in exchange for All-Star closer Craig Kimbrel. The trade represented a significant opportunity for Heuer to continue his major league career with another Chicago franchise. After joining the Cubs, he appeared in 25 games and went 3-3 with a 3.14 earned run average and 17 strikeouts over 28 and two-thirds innings.
His 2022 season was derailed before it began when Heuer underwent Tommy John surgery on March 8, 2022, an injury that required extensive rehabilitation and forced him to miss the entire campaign. He returned to action in 2023, agreeing to a one-year contract worth $785,000 with the Cubs in January and avoiding salary arbitration. After making 15 rehab appearances with the Triple-A Iowa Cubs, Heuer suffered an elbow fracture that required season-ending surgery in June, further delaying his return to form.
Texas Rangers and Detroit Tigers (2025)
Heuer signed a minor league contract with the Texas Rangers on April 6, 2024, beginning his journey back to the major leagues. In 2025, he returned to action with the Triple-A Round Rock Express, where he posted a 2-1 record with a 3.27 earned run average and 25 strikeouts across 19 appearances. His strong performance earned him a promotion when Texas selected his contract and added him to their major league roster on June 1, 2025.
Heuer made one appearance for the Rangers, allowing one run across one and one-third innings against the Tampa Bay Rays. Less than two months later, on July 31, 2025, he was traded to the Detroit Tigers in exchange for cash considerations. He appeared in two games for the Tigers, recording a 5.40 earned run average with four strikeouts across three and one-third innings pitched. The Tigers released him on September 18, 2025, ending his brief tenure with the organization.
Cleveland Guardians Era (2026–Present)
On December 22, 2025, Heuer signed a minor league contract with the Cleveland Guardians. The Guardians selected his contract on March 22, 2026, and subsequently optioned him to the Triple-A Columbus Clippers to begin the season. This move represented another opportunity for Heuer to work toward a sustained role at the major league level with a new organization.
Driving Style and Strengths
Throughout his career, Heuer has established himself as a reliable bullpen arm capable of handling high-leverage situations. His ability to pitch effectively in relief roles has been a consistent trait, particularly during his early major league seasons with Chicago. His strikeout ability has translated across levels, and his experience as both a starter and reliever provides flexibility for his teams. The transition from starting to relief pitching during his minor league career demonstrated his adaptability and willingness to fill whatever role his team requires.
Notable Events and Milestones
Heuer’s career has been marked by several significant moments including his major league debut against the Minnesota Twins in July 2020 and his selection to the White Sox Opening Day roster that same year. His participation in the trade for Craig Kimbrel highlighted his value as a prospect. The Tommy John surgery in 2022 represented a major setback, but his persistence in returning to the majors with multiple organizations demonstrates his determination to continue his professional career.
