Timothy Gerard Mayza Bio
Timothy Gerard Mayza is an American professional baseball pitcher and relief specialist who has played in Major League Baseball since his debut in 2017. Drafted by the Toronto Blue Jays in the 12th round of the 2013 MLB draft, Mayza established himself as a reliable bullpen arm across multiple organizations, appearing for the Toronto Blue Jays, New York Yankees, Pittsburgh Pirates, and Philadelphia Phillies.
Early Life and Background
Timothy Gerard Mayza was born on January 15, 1992, in Red Hill, Pennsylvania. He is the eldest of four children of Jerry Mayza and Marlene Mayza; his father played NCAA Division III basketball and his sister Deanna competed in college basketball, reflecting a family engaged in organized sports.
Mayza attended Upper Perkiomen High School in Red Hill, where he played baseball, basketball, and soccer. As a sophomore he threw a no-hitter, and in his final high school season he posted a 5–3 record with a 2.73 earned run average and 53 strikeouts in 51 innings. He continued his education and baseball development at Millersville University of Pennsylvania, pitching for the Millersville Marauders and spending a summer in 2012 with the Cotuit Kettleers of the Cape Cod Baseball League.
Path to Baseball
After a standout senior season at Millersville in which he recorded an 11–3 record, a 1.55 ERA, and 91 strikeouts, Mayza attracted professional interest and was selected by the Toronto Blue Jays in the 12th round of the 2013 MLB draft. He signed for a reported $100,000 bonus and began his professional career in the Blue Jays’ rookie system, moving quickly through short-season and low-A assignments in his first year.
Mayza’s progression through the Blue Jays’ minor league system was steady. He spent time with Bluefield and Vancouver in 2014, worked the full 2015 season with Single-A Lansing, and climbed to High-A Dunedin and Double-A New Hampshire in 2016. Improved performance at each level, including a 2.25 ERA across 64 innings in 2016, earned him a major league spring training invite and eventual promotion to the Triple-A Buffalo Bisons in 2017 before his MLB debut later that year.
Timothy Gerard Mayza Career
Early Career (2013–2016)
Mayza began his professional career in 2013 in the Blue Jays rookie system after the draft. In limited appearances that year he was promoted from the Gulf Coast League to the Appalachian League’s Bluefield Blue Jays and finished with 27 strikeouts in 29 innings. The following seasons saw Mayza work across low-A and Single-A levels, where he refined his arm as a reliever and improved his strikeout and control metrics.
By 2015 and 2016 Mayza had become a regular late-inning option in the minors. He posted a 3.07 ERA with 62 strikeouts in 2015 across 55 2/3 innings for Lansing, then produced a 2.25 ERA with 65 strikeouts in 64 innings across High-A and Double-A in 2016, setting up his invitation to major league spring training and his promotion path to Triple-A and the majors in 2017.
Toronto Blue Jays Breakthrough (2017–2024)
On August 14, 2017, Timothy Gerard Mayza was promoted to the major leagues for the first time, and he made his MLB debut on August 15, 2017, pitching a scoreless ninth inning while recording his first major league strikeout. He earned his first major league win on September 12, 2017, after appearing in relief during a walk-off victory for the Blue Jays. Those early appearances established him as a bullpen option for Toronto.
Mayza split time between the Blue Jays and their Triple-A affiliate in 2018 and logged 37 major league games that season with a 3.28 ERA and 40 strikeouts over 35 2/3 innings. He spent much of 2019 as a frequent reliever, appearing in 68 games before suffering a torn UCL in September 2019 that required Tommy John surgery. After missing the 2020 season for recovery, Mayza returned to the Blue Jays’ bullpen and posted effective seasons across 2021 through 2023, including an 8–1 record with a 3.14 ERA in 2022 and a 1.52 ERA in 69 appearances in 2023.
New York Yankees (2024)
Mayza signed a minor league contract with the New York Yankees on July 10, 2024, and after strong Triple-A work was selected to the major league roster in August. In 15 appearances for New York he recorded a 4.00 ERA with 12 strikeouts over 18 innings. The Yankees non-tendered Mayza in November 2024, making him a free agent.
Pittsburgh Pirates Era (2025)
Tim Mayza signed a one-year contract with the Pittsburgh Pirates on February 3, 2025. He opened the season on the active roster and made seven appearances, recording a 2.89 ERA with eight strikeouts across 9 1/3 innings before a lat strain and teres major injury in April led to a six-week shutdown and placement on the 60-day injured list. The Pirates placed Mayza on release waivers later in the season.
Philadelphia Phillies Era (2025–Present)
On August 31, 2025, Mayza was claimed off waivers by the Philadelphia Phillies. He made eight appearances for Philadelphia late in the 2025 season, posting a 4.91 ERA with seven strikeouts across 7 1/3 innings. Mayza re-signed with the Phillies organization on a minor league contract in January 2026 and was later signed to a major league contract in March 2026, remaining with the club into the 2026 season.

Notable Events and Milestones
Key moments in Mayza’s career include his major league debut on August 15, 2017, his first win on September 12, 2017, undergoing Tommy John surgery after a 2019 UCL tear, and his role in Toronto’s bullpen during the 2022 and 2023 seasons. On September 28, 2022, he was the pitcher who surrendered Aaron Judge’s 61st home run of that season, tying the American League single-season record at the time.
