Corbin Martin Bio
Corbin Montgomery Martin (born December 28, 1995) is an American professional baseball pitcher who has played in Major League Baseball (MLB) for the Houston Astros, Arizona Diamondbacks, and Baltimore Orioles. A right-handed starter who has shifted into a relief role in recent seasons, Martin began his professional career in the Houston Astros system after a standout amateur career in Texas. He is the son of a college baseball coach and the older brother of fellow pitcher Drew Martin.
Early Life and Background
Corbin Montgomery Martin was born on December 28, 1995, and grew up in Cypress, Texas, a suburb of Houston. He attended Cypress Ranch High School, where he was a two-sport athlete in baseball and football. Martin drew early attention as a pitcher with a strong frame and a power arm, and his development drew interest from college scouts across the region.
After high school, Martin played college baseball at Texas A&M University, where he continued to refine his command and pitch repertoire. In 2016, he played collegiate summer baseball with the Falmouth Commodores of the Cape Cod Baseball League, a respected developmental circuit for top college players. He was selected by the Houston Astros in the second round of the 2017 MLB draft and chose to begin his professional career.
Path to Professional Baseball
Martin signed with the Houston Astros and was assigned to the Gulf Coast League Astros and the short-season Tri-City ValleyCats in 2017. Across 32.2 innings that year, he posted a 2.20 ERA while adjusting to professional hitters. In 2018, he moved up to the Buies Creek Astros of the Carolina League and was promoted midseason to the Double-A Corpus Christi Hooks, going a combined 9–2 with a 2.51 ERA in 25 games and 21 starts.
He opened 2019 with the Triple-A Round Rock Express, logging a 2–1 record and a 3.13 ERA in 37 innings, which earned him his first big-league opportunity. On May 12, 2019, Martin made his major league debut with the Houston Astros against the Texas Rangers. In five starts for Houston that season, he went 1–1 with a 5.59 ERA in 19 innings, showing flashes of his potential before a July 3 Tommy John surgery ended his year and required a long rehabilitation.
Corbin Martin Career
Early Career (2017–2019)
Martin’s first full professional season came in 2018, when his 9–2 record and 2.51 ERA across two levels established him as one of the top arms in the Astros system. His quick rise through the minor leagues was capped by a May 2019 promotion to the major leagues, where he handled a difficult assignment against the Texas Rangers in his debut. The 2019 season ended on a difficult note when he underwent Tommy John surgery in July, beginning a long and winding road back to the majors.
On July 31, 2019, he was traded to the Arizona Diamondbacks as part of the package for veteran ace Zack Greinke. He then spent the rest of 2019 and all of 2020 recovering from his elbow reconstruction, working his way back to game action in the minor leagues.
Arizona Diamondbacks (2021–2024)
Martin returned from Tommy John surgery in 2021 and made five appearances for the Arizona Diamondbacks, struggling to a 10.69 ERA and an 0–3 record before a lat injury and a shutdown sidelined him for the rest of the year. In 2022, he bounced between the majors and Triple-A Reno, going 0–1 with a 4.84 ERA in 22⅓ innings for Arizona, while also posting a 6–7 record with the Reno Aces.
His Diamondbacks tenure ended on a difficult note. On March 15, 2023, Martin tore the lat tendon under his right shoulder during a spring training game, opted for surgery, and missed the entire 2023 season. He returned to Triple-A Reno in 2024, was designated for assignment on April 7, and was claimed off waivers by the Milwaukee Brewers on April 14, 2024. He made seven appearances for the Triple-A Nashville Sounds before being designated for assignment again on May 10.
Baltimore Orioles (2024–2025)
On May 13, 2024, Martin was claimed off waivers by the Baltimore Orioles and assigned to the Triple-A Norfolk Tides. In 29 appearances for Norfolk, he went 1–2 with a 4.05 ERA and 31 strikeouts in 33⅓ innings. After beginning 2025 in Triple-A, he was selected to Baltimore’s active roster on July 2, 2025, made a scoreless appearance, and was designated for assignment on July 13. He elected free agency on July 17 and re-signed with the Orioles on a major league contract the next day, finishing 2025 with a 1–0 record, 6.00 ERA, two saves, and 23 strikeouts in 18 innings across 17 appearances. He was designated for assignment on September 2 and elected free agency on September 30.
Chicago Cubs Era (2026)
On January 12, 2026, Martin signed a minor league contract with the Chicago Cubs and was assigned to the Triple-A Iowa Cubs. The Cubs selected his contract on April 18, 2026, and he made seven appearances for the team, struggling to a 10.80 ERA with four strikeouts and one save across five innings. He was designated for assignment on May 7, cleared waivers, and was sent outright to Triple-A Iowa on May 10.
Notable Events and Milestones
Martin’s career has been defined as much by resilience as by results. His major league debut on May 12, 2019, against the Texas Rangers marked the arrival of a top Astros prospect, only for a Tommy John surgery months later to interrupt his momentum. Trades involving Zack Greinke and repeated waiver moves have carried him across the league, while his first MLB save in 2025 with the Orioles underscored his growing comfort in late-inning relief work.
