Troy Taylor Bio
Troy Jonathan Taylor, born on September 9, 2001, in Rancho Cucamonga, California, is an American professional baseball pitcher for the Seattle Mariners of Major League Baseball (MLB). A right-handed reliever, Taylor made his MLB debut in 2024 and quickly drew attention for a high-velocity fastball that averaged 97 miles per hour. He wears uniform number 59 for Seattle and works primarily as a late-inning relief option.
Before reaching the major leagues, Taylor developed through the Mariners’ minor league system after being selected in the 2022 MLB draft. His rise from a college convert at Cal State Long Beach to a big-league reliever has positioned him as a young arm to watch in the Seattle bullpen.
Early Life and Background
Troy Jonathan Taylor grew up in Rancho Cucamonga, California, in a supportive family environment shaped by his parents, Earl and Susan Taylor. He has an older sister named Jenna, who works as an accountant. The Southern California region has long produced talented baseball players, and Taylor grew up surrounded by year-round competitive baseball opportunities that helped him develop his skills from a young age.
He attended Los Osos High School in Rancho Cucamonga, where he graduated in 2019. In his senior season, Taylor was named team MVP and earned all-league recognition for his play, marking him as a promising prospect before moving on to the college ranks.
Path to Baseball
Following high school, Taylor began his college baseball career at Cal State Long Beach in 2020. During that season, he converted to pitcher, a positional change that ultimately defined his future. He appeared in one game for the Dirtbags, allowing a run while recording four outs in a loss to Mississippi State.
After one year at Long Beach, Taylor transferred to Cypress College, where he spent a single season before pitching for the Williamsport Crosscutters in the MLB Draft League. With Williamsport, he was named the team’s pitcher of the year and led the league with 52⅔ innings pitched. The Seattle Mariners selected him in the 20th round of the 2021 MLB draft, but he did not sign, choosing instead to transfer to UC Irvine for the 2022 college season, where he led the Anteaters with six saves.
Troy Taylor Career
Early Career (2022–2023)
The Seattle Mariners selected Troy Taylor in the 12th round of the 2022 MLB draft, and this time he signed with the club, receiving a $125,000 signing bonus. He made his professional debut in April 2023 with the Single-A Modesto Nuts before earning a promotion in August to the High-A Everett AquaSox. Across 40 appearances and 45⅓ innings with the two affiliates, he posted a 3.38 ERA with 62 strikeouts and three saves.
Following the 2023 minor league season, Taylor pitched for the Peoria Javelinas in the Arizona Fall League, recording one win and one save across nine appearances. His strong fall performance earned him a selection to the 2023 Fall Stars Game, signaling the organization’s growing confidence in his future role.
Minor League Breakthrough (2024)
Taylor returned to Everett to open the 2024 season before being promoted to the Double-A Arkansas Travelers in May 2024. In 40 minor league games that year, he accumulated 21 saves with a 3–4 record and a sharp 1.69 ERA over 42⅔ innings, cementing his status as a closer candidate. His combination of swing-and-miss stuff and poise on the mound convinced the Mariners that he was ready for a look in the major leagues.
Seattle Mariners Era (2024–Present)
On August 10, 2024, the Mariners selected Taylor to the 40-man roster and promoted him to the major leagues. He made his MLB debut the following day against the New York Mets, striking out two batters and walking one in the ninth inning of a 12–1 win. He surrendered his first MLB home run to Javier Báez of the Detroit Tigers in his next appearance on August 13.
Taylor earned his first MLB save on September 27, 2024, when he recovered from a leadoff double and a wild pitch to record three consecutive outs against the Oakland Athletics. Pitching primarily as a seventh-inning reliever, he finished his rookie season with a 3.72 ERA and 25 strikeouts across 19⅓ innings. According to Statcast, his fastball sat in the top 10 percent of MLB pitchers at an average of 97 mph, while his fastball spin rate ranked in the top 15 percent. His main secondary offering was a sweeper graded as slightly below average.
Driving Style and Strengths
Taylor’s game is built around a blazing fastball that averages 97 mph and generates elite spin rates, giving him the ability to miss bats in high-leverage spots. He relies on that heater to set up a sweeper as his primary secondary pitch, and his aggressive mound presence has translated into a late-inning relief role with Seattle. His minor league track record of high save totals demonstrates the bullpen trust the organization has placed in his development.
Notable Events and Milestones
Key milestones in Troy Taylor’s young career include his first MLB strikeout on August 11, 2024, his first MLB save on September 27, 2024, and a selection to the 2023 Arizona Fall League Fall Stars Game. His 21 saves in the minors during 2024 underscored his closing profile before reaching the majors.

Troy Taylor Family
Family Background and Personal Life
Troy Taylor is the son of Earl and Susan Taylor, and he has an older sister, Jenna, who works as an accountant. The Taylor family remained supportive throughout his baseball journey, from his high school days at Los Osos High School through his college stops and into professional baseball. His Southern California upbringing has kept him close to family throughout his career.
Personal Life
Taylor’s life outside of baseball centers on family, with his parents Earl and Susan and his sister Jenna remaining important figures in his support system. His path from a college position-player convert to MLB reliever reflects a personal commitment to refining his craft in a new role on the mound.
2025 Season Performance
Troy Taylor’s 2025 season was interrupted by a lat strain suffered in January, which Mariners general manager Jerry Dipoto said could delay the start of his year. After recovering, he returned to the Seattle bullpen and made eight regular-season appearances, posting a 12.15 ERA with two strikeouts across 6⅔ innings pitched. The limited sample reflected a transitional year as he worked his way back from the injury.
Looking forward, Taylor was optioned to Triple-A Tacoma to begin the 2026 season, giving him an opportunity to refine his command and rebuild momentum. His minor league option status and the Mariners’ continued investment in his high-velocity arm suggest he remains firmly in the team’s bullpen plans. If he can pair his 97 mph fastball with sharper secondary offerings, Taylor is well positioned to rejoin the late-inning mix in Seattle.
