Marlins to call up Jakob Marsee

[Kevin Barral]

Sources tell Fish On First that outfielder Jakob Marsee (FOF #23 prospect) has been called up and will make his major league debut against the New York Yankees this weekend. The club has yet to confirm any roster move.

This promotion comes immediately after the Marlins traded away Jesús Sánchez to the Houston Astros in exchange for three players.

Marsee, 24, was one of four players acquired in the Luis Arraez trade early last season. He will become the first player from that package to debut in the big leagues. Through 98 games this year with Triple-A Jacksonville, Marsee is slashing .246/.379/.438/.817 with 14 home runs, 37 RBI, 47 stolen bases and a 125 wRC+. He ranks in the 93rd percentile among all AAA hitters in chase rate, per Prospect Savant.

"His average exit velo is up like six miles an hour right now compared to last year," said AAA hitting coach Mike Marjama a couple days ago. "His BABIP actually down, which is even more encouraging. Seeing some of the things and the process metrics show up again and again, he's one of those guys who had a little rocky start at the beginning, but now that we've gotten to know each other, better in communication, it's been super helpful and the trust factor is there. He's a Detroit kid, a hard-nose underdog and so watching him come in, chip on his shoulder, compete, he's the heartbeat of our team."

Marsee should be starting whenever Miami faces right-handed pitching, likely platooning with the right-handed-hitting Heriberto Hernández. He has a .857 OPS against righties in 2025.

Defensively, Marsee plays all three outfield spots, but profiles best in center with his speed and route-running. The Marlins could shift Dane Myers to right field on days when they're in the lineup together.

The Marlins and Yankees kick off a three-game set on Friday with first pitch slated for 7:10 pm. Marsee will likely be in the lineup on both Saturday and Sunday against right-handers Cam Schlittler and Luis Gil.
