Troy Johnston Bio
Troy Michael Johnston is an American professional baseball first baseman and outfielder for the Colorado Rockies of Major League Baseball (MLB). He made his MLB debut in 2025 with the Miami Marlins and was claimed off waivers by the Colorado Rockies in November 2025. Johnston was originally selected in the 2019 MLB Draft by the Marlins and worked his way through the minor leagues before earning his first big-league call-up. He bats and throws from the left side and is regarded as a contact-oriented hitter with emerging pop and speed on the base paths.
Early Life and Background
Troy Michael Johnston was born on June 22, 1997, in Puyallup, Washington, United States. He grew up in the Pacific Northwest and attended Governor John R. Rogers High School in Puyallup, where he played on the school’s baseball program. The Pacific Northwest’s strong amateur baseball culture gave him an early foundation in the sport, and he continued to develop his skills through travel and high school competition.
After completing high school, Johnston enrolled at Gonzaga University in Spokane, Washington, where he played college baseball for the Gonzaga Bulldogs. His time in the West Coast Conference allowed him to face high-level college pitching and further refine his left-handed swing. The combination of his high school preparation and his college experience positioned him as a draft-eligible prospect following his junior season.
Path to Professional Baseball
Johnston’s path to the professional ranks began in 2019, when he was selected by the Miami Marlins in the 17th round of the 2019 Major League Baseball draft, with the 501st overall pick. He signed with the organization and was assigned to the Batavia Muckdogs, the Marlins’ former short-season affiliate, where he made his professional debut. The transition from college ball to the professional ranks required adjustments to wood bats, longer schedules, and the rigors of everyday play.
The 2020 minor league season was canceled because of the COVID-19 pandemic, which cost Johnston a full year of development. He returned to action in 2021, splitting the season between the Jupiter Hammerheads and the Beloit Snappers, and later gained additional at-bats in the Arizona Fall League. He opened 2022 with the Double-A Pensacola Blue Wahoos, continuing his climb up the Marlins’ system and demonstrating the consistency that kept him on the organization’s prospect map.
Troy Johnston Career
Early Career (2019–2022)
Johnston made his professional debut in 2019 with the Batavia Muckdogs after being drafted in the 17th round by the Miami Marlins. He showed promising contact skills in his first taste of pro ball, earning positive reviews from the Marlins’ player development staff. The cancellation of the 2020 minor league season briefly halted his progress, but he returned to competition in 2021 with Jupiter and Beloit, where he continued to refine his approach at the plate and his work at first base.
Following the 2021 season, Johnston was sent to the Arizona Fall League, a prestigious finishing school for top prospects. He opened 2022 with the Pensacola Blue Wahoos of the Double-A Southern League, where he cemented his profile as a steady, left-handed hitting first baseman. His steady production at Pensacola kept him firmly within the Marlins’ organizational plans and laid the groundwork for his eventual major-league opportunity.
Miami Marlins (2025)
Johnston began the 2025 season with the Triple-A Jacksonville Jumbo Shrimp, where he posted a slash line of .252/.333/.439 with 12 home runs, 39 runs batted in, and 31 stolen bases over his first 84 games. His blend of on-base skills, modest power, and baserunning threat made him one of the Marlins’ more intriguing depth options at first base and in the outfield. On July 29, 2025, he was added to the 40-man roster and promoted to the major leagues for the first time.
Johnston wasted little time making an impact at the highest level. On August 16, 2025, he hit his first career major-league home run, a solo shot off Boston Red Sox pitcher Brayan Bello. He appeared in games for the Marlins as a first baseman and outfielder, providing left-handed pop and defensive flexibility. His big-league debut season with Miami established him as a major-league regular heading into the offseason.
Colorado Rockies Era (2025–Present)
On November 5, 2025, Troy Michael Johnston was claimed off waivers by the Colorado Rockies, marking the next step in his major-league career. The move gave the Rockies another left-handed bat with first-base and corner-outfield versatility, while giving Johnston a fresh opportunity in a new organization. The transition came shortly after his debut season, allowing him to enter spring training in 2026 with a full major-league campaign already under his belt.
For Johnston, the waiver claim represented both an organizational change and a vote of confidence from a National League West club in need of offensive depth. He is expected to compete for playing time at first base, in left field, and as a designated hitter, areas where his contact approach and baserunning can play. The Colorado Rockies Era begins with Johnston still on his rookie calendar and looking to build on the foundation he established with Miami.
Driving Style and Strengths
Johnston is regarded as a contact-oriented left-handed hitter with a smooth, level swing and a patient approach at the plate. His minor-league track record demonstrates the ability to make consistent hard contact, work counts, and deliver extra-base hits, while his 31 stolen bases in 84 Triple-A games in 2025 highlighted an underrated baserunning element. Defensively, he offers positional flexibility, having played both first base and the outfield, which gives managers options when constructing lineups.
Notable Events and Milestones
Johnston’s most significant milestone to date is his major-league debut on July 29, 2025, with the Miami Marlins, the realization of a path that began with the 501st overall pick in the 2019 draft. Less than three weeks later, on August 16, 2025, he hit his first career MLB home run off Brayan Bello of the Boston Red Sox, a memorable early highlight. The November 5, 2025 waiver claim by the Colorado Rockies added another chapter, confirming his status as a major-league player heading into his second big-league season.
