Tanner Lee Houck is an American professional baseball pitcher for the Boston Red Sox of Major League Baseball (MLB). Born on June 29, 1996, in Collinsville, Illinois, Houck was drafted by the Red Sox with the 24th overall pick in the 2017 MLB draft after playing college baseball at the University of Missouri. Standing 6 feet 5 inches tall and weighing 230 pounds, he throws and bats right-handed. Houck made his MLB debut in September 2020 and has since become a key figure in Boston’s pitching rotation. He earned his first All-Star selection in 2024, a season in which he posted a career-best 3.12 earned run average.
Early Life and Background
Tanner Houck grew up in Collinsville, Illinois, where he attended Collinsville High School. During his high school years, Houck demonstrated significant talent as a pitcher, catching the attention of Major League Baseball scouts. His family experience shaped his character, as his parents adopted a 4-year-old girl while Houck was a freshman in high school, an event that inspired his lifelong commitment to adoption advocacy.
In addition to his baseball pursuits, Houck played for the United States collegiate national team during the summer of 2015. Against Cuba, he combined with A.J. Puk and Ryan Hendrix to throw a no-hitter, showcasing his early potential on the international stage.
Path to Professional Baseball
Houck’s impressive high school performance led to him being selected by the Toronto Blue Jays in the 12th round of the 2014 MLB draft. However, he chose not to sign and instead attended the University of Missouri to play college baseball for the Tigers. This decision proved instrumental in his development as a pitcher.
As a freshman at Missouri in 2015, Houck made an immediate impact, starting 15 games and posting an 8-5 record with a 3.49 earned run average and 91 strikeouts against only 12 walks in over 100 innings pitched. His sophomore season saw continued improvement, with Houck going 5-6 but lowering his ERA to 2.99 while recording 106 strikeouts in 15 starts.
Tanner Houck Career
Minor Leagues (2017–2019)
The Boston Red Sox selected Houck with the 24th overall pick in the 2017 MLB draft. He signed with the organization on June 21, 2017, and was assigned to the Low-A Lowell Spinners, where he spent the entire season. In 22 and one-third innings pitched, Houck compiled a 0-3 record with a 3.63 earned run average.
During the 2018 season with the Class A-Advanced Salem Red Sox, Houck made 23 starts and experienced some struggles, finishing with a 7-11 record and a 4.24 earned run average. The following year proved to be a breakthrough at the Double-A level. Houck began 2019 with the Portland Sea Dogs before earning a promotion to the Triple-A Pawtucket Red Sox on July 13. Overall, he went 8-6 with a 4.01 earned run average and 107 strikeouts in 107 and two-thirds innings. After the regular season, Houck continued his development in the Arizona Fall League with the Peoria Javelinas.
Boston Red Sox Breakthrough (2020–2021)
Due to the start-delayed 2020 MLB season caused by the pandemic, Houck received his major league call-up. He made his MLB debut against the Miami Marlins on September 15, 2020, allowing just two hits and no runs while striking out seven batters across five innings pitched. Notably, Houck pledged to donate $100 for each strikeout to his charity, Pitch for Adoption, resulting in a $700 donation following that debut performance. He became only the fourth player in Red Sox history to strike out seven or more batters without allowing any runs in a debut game.
In his second start against the New York Yankees on September 20, Houck took a no-hitter into the sixth inning, exiting the game with just one hit and one unearned run allowed. Overall during the abbreviated 2020 season, he appeared in three games (all starts), compiling a perfect 3-0 record with a remarkable 0.53 earned run average and 21 strikeouts in 17 innings pitched. Following the season, Baseball America ranked Houck as the Red Sox’ number eight prospect.
The 2021 season saw Houck split time between Boston and the alternate training site. He earned his first major-league save on July 16, pitching the final three innings of a 4-0 victory over the Yankees in The Bronx. Houck was optioned and recalled from Triple-A Worcester several times during July and August. Overall, he made 18 appearances (13 starts) for Boston, compiling a 1-5 record with a 3.52 earned run average and 87 strikeouts in 69 innings pitched.
Injury Challenges (2022–2023)
Houck began the 2022 season in the Red Sox starting rotation. He was placed on the restricted list prior to a late April series in Toronto because he was apparently not vaccinated against COVID-19, which was required to enter Canada. He re-joined the team on April 29 in Baltimore but was again placed on the restricted list when the team returned to Toronto in late June. On August 9, Houck was placed on the injured list due to lower-back inflammation, and on September 3, Red Sox manager Alex Cora announced that he would undergo season-ending back surgery. In 32 appearances (four starts) during 2022, he recorded a 5-4 record with eight saves and a 3.15 earned run average while striking out 56 batters in 60 innings pitched.
The 2023 season brought more injury adversity. While serving as a starter, Houck was struck by a line drive during a home game against the Yankees on June 16, resulting in a facial fracture and a subsequent injured list stint. He returned to Boston’s active roster on August 22. For the season, Houck posted a 6-10 record with a 5.01 earned run average, striking out 99 batters in 106 innings.
All-Star Season (2024)
Houck returned to form in 2024, beginning the season as a key component of Boston’s rotation. On April 17, 2024, he threw a “Maddux” against the Cleveland Guardians, completing his first complete game shutout in just 94 pitches. The game lasted 1 hour and 49 minutes, marking the shortest nine-inning game since Armando Galarraga’s near-perfect game in 2010. This was also the first complete-game shutout for the Red Sox since Michael Wacha on June 6, 2022, and the first Maddux for Boston since Clay Buchholz in 2014.
Houck continued his strong performance through the first half of the season, earning a selection to the 2024 All-Star Game. He pitched the third inning for the victorious American League, allowing the only runs the National League scored (three runs on four hits) while recording one strikeout. After the All-Star break, Houck experienced some regression, posting a 1-4 record with a 4.23 earned run average in 11 starts. Despite the second-half struggles, he finished the season with a 9-10 record and a career-best 3.12 earned run average. Houck also set career highs in innings pitched (178 and two-thirds) and strikeouts (154), starting 30 games.
2025 Season
Houck began the 2025 season with high expectations as the number-two starter behind newly acquired ace Garrett Crochet. However, he struggled significantly early in the campaign. His first start saw him allow four runs on seven hits across five and two-thirds innings. On April 15, Houck endured a disastrous outing against the Tampa Bay Rays, permitting 12 runs (11 earned) in just two and one-third innings. This marked the most earned runs allowed in that few innings in franchise history and made him the first Red Sox pitcher to allow 12 runs in a game since Galen Cisco in 1962.
Despite showing occasional signs of improvement, including a seven-inning, six-strikeout performance against the Toronto Blue Jays, Houck continued to experience difficulties. On May 12, he allowed 11 earned runs against the Detroit Tigers in just two and one-third innings, becoming the first Red Sox pitcher since Wes Ferrell in 1936 to allow 10 or more earned runs in multiple appearances within a single season. Houck was placed on the 60-day injured list on July 31 following a failed rehab assignment due to a right flexor pronator strain. On August 2, it was revealed that he would require Tommy John surgery. He ended the season with an 0-3 record, 32 strikeouts, and an 8.04 earned run average. On August 18, the Red Sox announced that Houck had successfully undergone hybrid reconstruction of his right ulnar collateral ligament with a flexor tendon repair. On February 10, 2026, he was transferred to the 60-day injured list as he continued his recovery.

Boston Red Sox Highlights
Houck’s most successful season came in 2024 when he earned his first All-Star selection while posting a career-best 3.12 earned run average. His April 17, 2024 complete-game shutout against the Cleveland Guardians stands as one of the most efficient performances in Red Sox history, requiring only 94 pitches. The 2020 season provided a remarkable introduction to major league baseball, as Houck went 3-0 with an 0.53 earned run average in his three starts. His 2022 season featured eight saves in relief appearances while maintaining a 3.15 earned run average.
Other Achievements

Tanner Houck Family
Family Background and Racing Lineage
Tanner Houck grew up in Collinsville, Illinois, with his family, who played a significant role in shaping his values and character. His parents adopted a 4-year-old girl while he was a high school freshman, an experience that profoundly influenced Houck and sparked his dedication to adoption causes. This family experience became the foundation for his charitable initiative, Pitch for Adoption.
Personal Life
Beyond his baseball career, Houck is known for his philanthropy through Pitch for Adoption, a charity he established to support adoption resources. Following his MLB debut, he donated $700 to the cause, with $100 contributed for each strikeout he recorded during that game. Houck’s commitment to giving back reflects the values instilled in him by his family. He continues to maintain connections to his Illinois roots while pursuing his professional baseball career in Boston.
2025 Season Performance
The 2025 season presented significant challenges for Tanner Houck as he struggled to find consistency in his role as Boston’s number-two starter. After a promising start to spring training, Houck experienced two catastrophic outings in April and May where he allowed 11 or more earned runs in each appearance, matching a franchise record not achieved since 1936. These struggles led to increased scrutiny of his mechanics and approach against major league lineups.
Despite glimpses of his potential, including a solid seven-inning performance against Toronto, Houck could not sustain positive momentum. The injury bug struck again when he suffered a right flexor pronator strain during a rehab assignment, ultimately requiring Tommy John surgery on August 2. The successful procedure marked the beginning of a lengthy recovery process that will likely keep him off the mound for the entirety of the 2026 season.
As Houck works through his rehabilitation, questions remain about his future role with the Boston Red Sox. The organization must balance patience with a pitcher who showed All-Star potential as recently as 2024 against the reality of a second major arm surgery in his career. His transition to the 60-day injured list in February 2026 signals that Boston is prepared to wait for his return, but the road ahead requires perseverance and careful management of expectations for the 29-year-old hurler.
