Caleb Boushley Bio
Caleb J. Boushley (born October 1, 1993) is an American professional baseball pitcher who currently plays for the KT Wiz of the KBO League in South Korea. A right-handed pitcher, he has built his career through the minor league systems of several Major League Baseball organizations before reaching the majors with the Milwaukee Brewers in 2023. He has since suited up for the Minnesota Twins, the Texas Rangers, and the Tampa Bay Rays at the major league level, gaining experience across both starting and relief roles.
After years spent climbing through the minor leagues, Boushley made his MLB debut late in the 2023 season and has continued to extend his professional career internationally. His move to the KBO League in late 2025 marked a new chapter abroad, where he joined the KT Wiz on a one-year contract. He wears jersey number 36 for the Wiz.
Early Life and Background
Caleb J. Boushley grew up in Wisconsin and developed his baseball skills in a region known for producing steady, hard-working athletes. He attended Hortonville High School in Hortonville, Wisconsin, where he played on the school team and began attracting attention from college recruiters. His performances at Hortonville laid the groundwork for his continued development as a pitcher.
Following high school, Boushley enrolled at the University of Wisconsin–La Crosse, a NCAA Division III program located in La Crosse, Wisconsin. He played college baseball for the Wisconsin–La Crosse Eagles, refining his mechanics and building the durability that would later define his professional career. The combination of his high school preparation and his college experience helped him earn an opportunity in professional baseball.
Path to Baseball
Boushley’s transition to professional baseball came in 2017 when the San Diego Padres selected him in the 33rd round of the Major League Baseball draft, with the 978th overall pick. The late-round selection did not stop him from steadily working his way up the Padres’ minor league ladder. He began his pro career that same year with the rookie-level Arizona League Padres and the High-A Lake Elsinore Storm, gaining valuable experience against older competition.
By 2018, Boushley had spent time with the Single-A Fort Wayne TinCaps and made a brief relief appearance for the Triple-A El Paso Chihuahuas, showing that he could handle advanced hitters. In 2019, he returned to Lake Elsinore for the full season and earned a spot in the 2019 California League All-Star Game, an early recognition of his growing reputation as a reliable arm in the Padres system.

Early Career (2017–2021)
Boushley’s earliest professional seasons were spent moving between levels within the San Diego Padres organization. He began with the Arizona League Padres and Lake Elsinore Storm in 2017, then advanced to Fort Wayne in 2018 while making a cameo appearance in Triple-A with El Paso. In 2019, he stayed with Lake Elsinore for the entire season and was selected for the California League All-Star Game, signaling that he was viewed as one of the top performers in that league.
The 2020 minor league season was canceled because of the COVID-19 pandemic, keeping Boushley off the field for a year. He returned in 2021, starting the year with the Double-A San Antonio Missions before earning a promotion to the Triple-A El Paso Chihuahuas in late June. On December 8, 2021, he was selected by the Milwaukee Brewers in the minor league phase of the Rule 5 draft, opening a new chapter in his development.
Milwaukee Brewers Breakthrough (2022–2023)
Boushley spent the 2022 season with the Triple-A Nashville Sounds, where he posted a 12–2 record with a 3.25 earned run average and 91 strikeouts across 127 and one-third innings in 25 starts. That performance established him as one of the top depth starters in the Brewers’ system and set the stage for his next opportunity.
He returned to Nashville in 2023, making 29 appearances with 26 starts and logging a 9–8 record alongside a 5.11 ERA and a career-high 110 strikeouts in 135 and two-thirds innings. On September 29, 2023, the Brewers selected his contract and he made his major league debut that same night against the Chicago Cubs. Boushley struck out five batters while allowing one hit and one earned run in two and one-third innings of relief, earning the win in his first big-league appearance. He was removed from the 40-man roster on October 31, 2023, and elected free agency on November 6.
Minnesota Twins Era (2024)
On January 26, 2024, Boushley signed a minor league contract with the Minnesota Twins and reported to the Triple-A St. Paul Saints. After five starts, he was added to Minnesota’s major league roster on May 1, 2024. His lone appearance came in relief against the Washington Nationals, where he allowed two runs in two innings of work.
Boushley was designated for assignment on July 14, 2024, cleared waivers, and was outrighted to St. Paul on July 16. He had his contract selected again on August 27, only to be designated for assignment a second time on September 1. He cleared waivers once more, returned to St. Paul on September 3, and elected free agency on October 11, 2024.
Texas Rangers Era (2025)
Boushley signed a minor league contract with the Texas Rangers on November 15, 2024, and reported to the Triple-A Round Rock Express. After two starts, the Rangers added him to their active roster on April 8, 2025. On May 30, 2025, he recorded his first career save after pitching three innings of relief in a victory over the St. Louis Cardinals, a memorable moment in his first extended stay in a major league bullpen.
In 24 appearances for Texas, Boushley posted a 5.74 ERA with 39 strikeouts across 42 and one-third innings pitched. The Rangers designated him for assignment on September 7, 2025. Just two days later, on September 9, the Tampa Bay Rays claimed him off waivers. With Durham, he made three appearances and recorded a 5.19 ERA with six strikeouts in eight and two-thirds innings before being designated for assignment by the Rays on November 3. He cleared waivers and elected free agency on November 6.
KT Wiz Era (2025–Present)
On November 26, 2025, Boushley signed a one-year, $900,000 contract with the KT Wiz of the KBO League, beginning his first stint playing professional baseball outside the United States. The move to South Korea offered him an opportunity to take on a prominent role in a foreign league and to extend his career on an international stage. Through early May 2026, he had recorded a 5–2 record with a 3.80 ERA and 39 strikeouts for the Wiz.
His transition to the KBO has allowed him to handle a larger workload than during his brief MLB bullpen stints, and he has emerged as a dependable arm for KT’s pitching staff. The combination of his major league experience and his college-era durability has helped him adjust quickly to the KBO’s offensive style.
Driving Style and Strengths
Across both starting and relief roles, Boushley has shown a profile built on command, durability, and the ability to miss bats when needed. His 110-strikeout season in 2023 with Nashville underscored his swing-and-miss ability at the upper levels of the minors, while his multi-inning relief appearances with Texas in 2025 demonstrated the versatility required to handle high-leverage late-inning work.
Notable Events and Milestones
Among the highlights of Boushley’s career are his major league debut win against the Chicago Cubs on September 29, 2023, his first career save against the St. Louis Cardinals on May 30, 2025, and his selection to the 2019 California League All-Star Game. His move to the KT Wiz in November 2025 also stands as a milestone, representing his first contract with a club outside the affiliated baseball system in the United States.
