Tommy Henry Bio
Thomas Jack Henry (born July 29, 1997) is an American professional baseball pitcher who has spent his career within the Arizona Diamondbacks organization. A left-handed starter, Henry played college baseball for the Michigan Wolverines and is best known for his dominant 2019 NCAA Tournament run, when he led Michigan to the 2019 College World Series finals. He made his Major League Baseball (MLB) debut in 2022 and has since appeared in parts of four big-league seasons with Arizona.
Originally drafted by the Diamondbacks in the 2019 MLB Draft, Henry has progressed through the club’s minor-league system, reaching Triple-A Reno and the major-league roster. Across his MLB career through the 2025 season, he has compiled a 10–11 win–loss record with a 5.07 earned run average (ERA) and 138 strikeouts. He remains a member of the Diamondbacks organization after re-signing on a minor-league deal in December 2025.
Early Life and Background
Henry attended Portage Northern High School in Portage, Michigan, where he developed into one of the top pitching prospects in the state. As a senior in 2016, he was named Michigan’s Mr. Baseball, an award given annually to the top high-school player in the state. That same season, he was also recognized as the Gatorade Player of the Year for Michigan, underscoring his status as one of the premier amateur pitchers in the region.
Coming out of high school, Henry drew college attention and committed to the University of Michigan, where he would go on to play three seasons of NCAA Division I baseball. His high-school accolades foreshadowed the breakthrough that would arrive on a national stage just three years later in 2019, when he emerged as one of college baseball’s most reliable postseason arms.
Path to Baseball
Henry began his collegiate career with the Michigan Wolverines, working his way into the weekend rotation as an underclassman. During the summers of 2017 and 2018, he sharpened his craft in the Cape Cod Baseball League, one of the most prestigious collegiate summer leagues in the country, suiting up for the Yarmouth-Dennis Red Sox. The Cape Cod League is widely regarded as a showcase for future professional talent, and Henry used his time there to build the stamina and command that would later define his college career.
As a junior in 2019, Henry became the staff leader for a Michigan team that would make a historic postseason run. His development under head coach Erik Bakich helped him refine a three-pitch mix and a willingness to attack hitters deep into games, traits that would carry him into the 2019 Major League Baseball Draft, where the Arizona Diamondbacks selected him with the 74th overall pick.
Tommy Henry Career
Early Career (2019–2021)
After being drafted by the Arizona Diamondbacks in 2019, Henry was assigned to the Hillsboro Hops, where he made three appearances and posted a 6.00 ERA over three innings. He did not pitch in a competitive game during 2020 because the minor-league season was cancelled due to the COVID-19 pandemic. The lost developmental year required Henry to build back his arm strength and sharpness the following spring.
In 2021, Henry returned to action with the Double-A Amarillo Sod Poodles, logging 23 starts and finishing with a 4–6 record and a 5.21 ERA while striking out 135 batters. The workload and strikeout totals reinforced his profile as a strike-throwing left-hander with swing-and-miss stuff, setting the stage for his first major-league opportunity the following year.
MLB Debut and Diamondbacks Tenure (2022–2023)
Henry began the 2022 season with the Triple-A Reno Aces before being selected to the 40-man roster and promoted to the major leagues for the first time on August 3, 2022. Six days later, on August 9, he earned his first career MLB win after pitching seven innings of one-run ball against the Pittsburgh Pirates. He went on to make nine appearances for the Diamondbacks that year, posting a 3–4 record and a 5.36 ERA with 36 strikeouts across 47 innings of work.
In 2023, Henry was optioned to Triple-A Reno to open the season but was recalled on April 24. Across 17 appearances and 16 starts, he went 5–4 with a 4.15 ERA and 64 strikeouts before being placed on the injured list on July 30 with left elbow inflammation, and was later transferred to the 60-day injured list on August 19. The injury cut short a season in which he had begun to show signs of becoming a reliable back-of-the-rotation starter.
Later MLB Seasons (2024–2025)
Henry made nine appearances and seven starts for the Diamondbacks during the 2024 campaign, compiling a 2–3 record and a 7.04 ERA with 30 strikeouts across 38 and one-third innings pitched. He was optioned to Triple-A Reno to begin the 2025 season and made two appearances for Arizona, recording a 4.05 ERA with eight strikeouts over six and two-thirds innings. On June 20, 2025, it was announced that Henry would require Tommy John surgery, ruling him out for the remainder of the season. He was designated for assignment by the Diamondbacks on November 18 and became a free agent on November 21 after being non-tendered. On December 1, 2025, he re-signed with the Diamondbacks on a minor-league contract.
Driving Style and Strengths

Coach Erik Bakich praised Henry’s ability to deliver in pressure moments, calling him the entire storyline of Michigan’s 2019 postseason run.
