Mason Montgomery Bio
Mason Jack Montgomery, born on June 17, 2000, is an American professional baseball pitcher who currently plays for the Pittsburgh Pirates of Major League Baseball (MLB). A left-handed pitcher raised in Texas, Montgomery first reached the major leagues with the Tampa Bay Rays in 2024 before being traded to Pittsburgh in December 2025. Across both stops, he has served as a relief pitcher, logging his appearances out of the bullpen while continuing to develop his craft.
Montgomery attended Leander High School in his hometown before spending three seasons at Texas Tech University, where he starred for the Texas Tech Red Raiders. Selected in the 2021 MLB Draft by the Rays, he progressed steadily through the minor leagues before earning a September 2024 promotion and making his big-league debut. He is now part of a young Pirates bullpen working to establish himself as a reliable late-inning option.
Early Life and Background
Mason Jack Montgomery was born on June 17, 2000, in Leander, Texas, and grew up in the same Central Texas community. The town, located just north of Austin, has produced a steady stream of baseball talent, and Montgomery developed his game on local fields while attending Leander High School. His upbringing in a baseball-rich region of Texas helped shape his early interest in pitching.
As a high school pitcher, Montgomery drew attention from professional scouts and was selected in the 39th round of the 2018 Major League Baseball draft by the Chicago White Sox. Rather than sign with the White Sox, he opted to continue his development in college, a decision that allowed him to refine his mechanics and gain valuable innings against higher-level competition.
Path to Baseball
After passing on the White Sox in 2018, Montgomery enrolled at Texas Tech University, where he played three seasons of college baseball for the Texas Tech Red Raiders. The program, based in Lubbock, gave him a platform to face some of the top hitters in collegiate baseball and to grow into a more complete pitcher. In his junior season, he posted a 5–3 win-loss record with a 3.82 earned run average (ERA) and 84 strikeouts in 63 and two-thirds innings across 14 outings, drawing praise for his strikeout ability.
That junior campaign helped elevate his draft stock, and on draft day in 2021, the Tampa Bay Rays selected Montgomery in the sixth round with the 191st overall pick. He signed with the organization and began his professional career that summer, setting in motion a rapid ascent through Tampa Bay’s farm system. The Rays’ reputation for pitcher development gave him a clear pathway to the majors.
Mason Montgomery Career
Early Career (2021–2022)
Following the 2021 draft, Montgomery was assigned to the Rookie-level Florida Complex League Rays, where he made an immediate impression. In his first professional stint, he allowed just one earned run while striking out 20 batters in 10 and two-thirds innings, a dominant showing that hinted at the strikeout profile he would carry through the minors.
Montgomery opened the 2022 season with the High-A Bowling Green Hot Rods and later earned a promotion to the Double-A Montgomery Biscuits, a club named in part for the region. Across 27 starts split between the two affiliates, he went 6–3 with a 2.10 ERA and recorded 171 strikeouts in 124 innings, cementing his status as one of the organization’s top pitching prospects.
Minor League Development (2023)
In 2023, Montgomery returned to the Double-A Montgomery Biscuits to begin the year before moving up to the Triple-A Durham Bulls. Across 29 combined starts, he compiled a 7–4 record and a 3.98 ERA with 144 strikeouts in 124 and one-third innings, demonstrating the workload durability expected of a future major-league starter. His progression to Triple-A signaled that he was nearing big-league readiness.
Tampa Bay Rays Era (2024–2025)
Montgomery began the 2024 season with the Triple-A Durham Bulls, where he struggled at times, going 1–7 with a 6.26 ERA and 105 strikeouts across 31 games and 14 starts. On September 5, 2024, the Rays selected him to the 40-man roster and promoted him to the major leagues for the first time. He made nine appearances for Tampa Bay during his rookie campaign, producing a 1.86 ERA with 17 strikeouts in 9 and two-thirds innings, a strong finish that hinted at his long-term potential.
Montgomery returned to the Rays’ bullpen in 2025, where he became a more regular contributor out of the bullpen. On June 18, 2025, he recorded his first career major-league win by tossing a scoreless inning against the Baltimore Orioles. Over the full season, he made 57 appearances for Tampa Bay, going 1–3 with a 5.67 ERA, 63 strikeouts, and one save across 46 innings of work.
Pittsburgh Pirates Era (2025–Present)
On December 19, 2025, the Rays sent Montgomery to the Pittsburgh Pirates in a three-team trade that also involved the Houston Astros. As part of the deal, the Pirates acquired Montgomery alongside Jake Mangum and Brandon Lowe, while the Astros received Mike Burrows, and the Rays brought in Jacob Melton and Anderson Brito. The move placed Montgomery in a new organization looking to reshape its pitching staff.
Montgomery joined the Pirates bullpen during the offseason and is expected to compete for a late-inning relief role in Pittsburgh. The trade gave him an opportunity to reset after an uneven 2025 and to showcase the swing-and-miss stuff that defined his climb through the minors. His transition marked a fresh chapter in a young career still taking shape.
Driving Style and Strengths
Throughout his career, Montgomery has been recognized primarily for his strikeout ability, having fanned 20 batters in just over 10 innings in his first professional assignment and piling up 171 punchouts in 124 innings at the High-A and Double-A levels in 2022. Scouts have credited him with a deceptive delivery and a sharp breaking ball that has produced swings and misses against both right- and left-handed hitters. As he has transitioned to relief work, the Rays and Pirates have leaned on his ability to miss bats in shorter outings.
Notable Events and Milestones
Among the defining moments of his early career, Montgomery’s major-league debut in September 2024 stands out as his first taste of MLB action, followed by his first career win on June 18, 2025, against the Baltimore Orioles. His inclusion in the three-team trade that brought Brandon Lowe to the Rays also marked a significant off-field milestone, signaling how teams valued his arm.
Mason Montgomery Career Wins
Montgomery’s verified major-league win total is limited to his time in the Tampa Bay Rays bullpen, where he earned his first career victory on June 18, 2025, against the Baltimore Orioles by recording a scoreless inning. Beyond that lone MLB win, he has notched several minor-league victories across multiple levels, including his 6–3 record at High-A Bowling Green and Double-A Montgomery in 2022 and a 7–4 mark split between Double-A and Triple-A in 2023.
Minor League Highlights
Montgomery’s minor-league résumé features two standout seasons. In 2022, he went 6–3 with a 2.10 ERA and 171 strikeouts across 124 innings between Bowling Green and the Montgomery Biscuits. In 2023, he added a 7–4 record and 3.98 ERA with 144 strikeouts in just over 124 innings across Double-A and Triple-A, reinforcing his profile as a power arm.
Other Performances
Outside of full-season affiliated play, Montgomery delivered a memorable debut with the Florida Complex League Rays in 2021, allowing one earned run with 20 strikeouts in roughly 10 innings. That brief but dominant stretch set the tone for the rest of his rise through the Rays’ system and remains one of the most efficient strikeout rates of his career.

2025 Season Performance
Mason Jack Montgomery spent the bulk of the 2025 season in the Tampa Bay Rays bullpen, ultimately making 57 appearances and posting a 1–3 record with a 5.67 ERA, 63 strikeouts, and one save across 46 innings. His most memorable moment came on June 18, 2025, when he recorded his first career win with a scoreless inning against the Baltimore Orioles. The numbers reflected an up-and-down year as he adjusted to a heavier big-league workload.
The Rays used Montgomery as a middle-relief option for much of the year, deploying him in a variety of late- and middle-inning situations. Despite his struggles with consistency, the team valued his swing-and-miss arsenal, and he remained an active part of the bullpen through season’s end. His usage suggested the Rays still viewed him as a long-term relief piece with further development ahead.
Montgomery’s 2025 campaign concluded with his inclusion in a three-team trade that sent him to the Pittsburgh Pirates on December 19, 2025. The deal signaled a fresh start for the young left-hander, who now joins a Pirates organization looking to inject new arms into its bullpen. Heading into 2026, Montgomery will look to build on his first MLB win and rediscover the dominance he showed in the lower minors.
