Jakob Marsee Bio
Jakob Joseph Marsee is an American professional baseball outfielder for the Miami Marlins of Major League Baseball (MLB). Born on 28 June 2001, he came up through the San Diego Padres organization before arriving in Miami and reaching the major leagues in 2025. A left-handed hitting outfielder with speed and on-base skills, Marsee earned the National League Rookie of the Month award in August 2025, the first major individual honor of his big-league career.
Early Life and Background
Jakob Joseph Marsee grew up in the Detroit area of southeastern Michigan and attended Allen Park High School in Allen Park, Michigan. He played multiple sports in his youth, but baseball became his primary focus as he developed into a promising outfield prospect. His high school performance drew the attention of college recruiters, and he ultimately committed to Central Michigan University to continue his playing career.
At Central Michigan, Marsee played college baseball in the Mid-American Conference and steadily built a reputation as a disciplined hitter and a plus runner in the outfield. During the summers he played in the Northwoods League, a wooden-bat collegiate league in the upper Midwest. In the pandemic-shortened 2020 season he joined the Great Lakes Resorters, a temporary team assembled to reduce travel, and he returned to the Northwoods League in 2021 with the Kokomo Jackrabbits and in 2022 with the Traverse City Pit Spitters, gaining valuable experience against top amateur competition.
Path to Baseball
Marsee entered professional baseball in 2022 when the San Diego Padres selected him in the sixth round of the Major League Baseball draft. He signed with the Padres that summer and began his pro career in the lower levels of the organization, splitting his first season between the Arizona Complex League Padres and the Low-A Lake Elsinore Storm. The Padres viewed him as a patient, contact-oriented hitter with the speed to play all three outfield spots.
In 2023 Marsee moved up to High-A Fort Wayne, where he opened the season with the TinCaps before earning a midyear promotion to the Double-A San Antonio Missions. Across 129 appearances between the two levels, he slashed .274/.413/.428 with 16 home runs, 46 runs batted in, and 46 stolen bases, showing a blend of on-base ability, pop, and baserunning that put him on the Padres’ prospect map.
Jakob Marsee Career
Early Career (2022–2023)
Marsee’s first full professional season came in 2022 across rookie and Low-A ball in the Padres system, where he adjusted to wooden bats and the daily grind of a 100-plus-game schedule. The Padres pushed him to High-A Fort Wayne to begin 2023, a vote of confidence in a player who had quickly refined his plate approach after signing.
By the end of 2023, his combination of on-base skills, doubles power, and stolen-base production had made him one of the more intriguing middle-of-the-diamond outfielders in the lower minors. The strong on-base percentage and the willingness to run made him an attractive target in trade discussions the following spring.
San Diego Padres and Trade Block (2022–2024)
Marsee spent his first two professional seasons inside the Padres system, climbing from the Arizona Complex League and Lake Elsinore to High-A Fort Wayne and Double-A San Antonio. In 2024 he was playing for the San Antonio Missions when the Padres pulled off a major trade that reshaped his career path.
On May 4, 2024, the Padres sent Marsee, along with outfielder Dillon Head, first baseman Nathan Martorella, and pitcher Woo-suk Go, to the Miami Marlins in exchange for All-Star second baseman Luis Arráez and cash considerations. Marsee and Martorella learned they were on the move while standing on base in the top of the third inning of a Missions game, a memorable interruption to a routine minor-league night.
Miami Marlins Era (2024–Present)
After the trade, Marsee joined the Double-A Pensacola Blue Wahoos, where he played 91 games and hit .188 with seven home runs, 37 runs batted in, and 32 stolen bases. He later earned a late-season promotion to the Triple-A Jacksonville Jumbo Shrimp, batting .275 with one home run, five runs batted in, and seven stolen bases in 22 games to finish 2024. The split showed glimpses of the offensive ceiling that the Marlins had acquired in the Arráez deal.
Marsee returned to Jacksonville to begin 2025 and spent most of the year there, slashing .246/.379/.438 with 14 home runs, 37 runs batted in, and 47 stolen bases across 98 games. On August 1, 2025, the Marlins selected his contract and added him to the 40-man roster, promoting him to the major leagues for the first time. In his MLB debut against the New York Yankees, Marsee recorded his first career hit and drew three walks, a textbook introduction built on his trademark plate discipline.
Notable Events and Milestones
Four days after his debut, Marsee hit his first major-league home run, connecting off Houston Astros pitcher AJ Blubaugh on August 5, 2025. Later that month, his strong start at the plate earned him the National League Rookie of the Month award for August 2025, the first monthly rookie honor of his career and an early signal of his impact in the Marlins lineup.
Jakob Marsee Career Wins
While wins and losses for position players are measured in offensive production rather than decisions, Marsee’s career has been defined by a series of personal milestones across multiple minor-league levels and, in 2025, the major leagues. His on-base skills, stolen-base totals, and power development have all contributed to a steady climb through professional baseball.
Minor League and MLB Highlights
Marsee’s most significant individual milestones include his 2023 season split between Fort Wayne and San Antonio, when he combined for 16 home runs and 46 stolen bases, and his 2024 split between Pensacola and Jacksonville, where he added another 39 stolen bases. His 47 stolen bases for Jacksonville in 2025 underscored his baserunning value immediately before his promotion to the majors. His first major-league hit, first major-league home run, and his August 2025 National League Rookie of the Month award marked the first signature achievements of his big-league career.

2025 Season Performance
Marsee spent the bulk of the 2025 season with the Triple-A Jacksonville Jumbo Shrimp, establishing himself as one of the Marlins’ most consistent offensive performers and baserunners at the top level of the minors. His .246/.379/.438 slash line, paired with 14 home runs and 47 stolen bases, gave Miami a clear case for a promotion once the major-league roster needed a spark. The Marlins called him up on August 1, inserting him into the outfield picture for the stretch run.
His major-league debut against the Yankees produced a first hit and three walks, immediately showing the plate discipline that had defined his minor-league track record. He added his first home run four days later off Houston’s AJ Blubaugh, and by the end of August he was named National League Rookie of the Month. The early returns suggested a player who could pair on-base skill with enough power and speed to remain a regular in the Marlins’ outfield plans going forward.
