Marlins hire Jack McMullen as new radio play-by-play voice

A young broadcaster from the Midwest will be steering Marlins radio coverage in 2025 and he'll be occasionally sharing the booth with former Fish closer AJ Ramos.

Jack McMullen has been hired to serve as the Miami Marlins' lead play-by-play radio broadcaster, multiple sources tell Fish On First. The team made it official with an announcement on Friday morning.

McMullen's duties previously belonged to Kyle Sielaff from 2023-2024. On January 17, Sielaff became the team's television play-by-play voice, necessitating a quick search for his successor.

This will be McMullen's first taste of the major league level. A 2020 graduate of Syracuse University, he was an announcer for the Triple-A affiliate of the Pittsburgh Pirates from 2022-2024 (sample here). The position involved both play-by-play and color commentary, plus creating digital content and assisting with media relations. He is also Just Baseball's director of podcasting, covering all 30 MLB organizations as host of The Just Baseball Show and The Call-Up.

McMullen is originally from Illinois. Follow him on Twitter.

McMullen is the fifth different lead radio voice that the Marlins franchise has had, joining Joe Angel, Dave Van Horne, Glenn Geffner and Sielaff.

Last season, Sielaff and Paul Severino provided play-by-play for practically every Marlins regular season game on radio and TV, respectively. In 2025, Craig Minervini will have an expanded role on both mediums. For "at least 35 games," McMullen and Minervini will share the radio booth and split up the play-by-play, according to the Miami Herald's Barry Jackson.

The Marlins have been using a rotation of radio analysts in recent years. In 2024, that included Kelly Saco (52 games), Rod Allen (40 games), Gaby Sanchez (40 games) and Jeff Nelson (22 games). Triple-A Jacksonville broadcaster Scott Kornberg did the remaining eight games in the booth. Kornberg was another candidate for the vacant play-by-play job, per sources.

AJ Ramos is being added to the rotation this season, Jackson reports. Ramos pitched parts of six seasons for the Marlins (2012-2017). He posted a 2.78 ERA and 3.24 FIP in 325 relief appearances, recording 92 saves and earning a 2016 NL All-Star selection.

Stephen Strom is entering his third season as Miami's pregame radio host. Before "passing the mic" to McMullen, Sielaff will co-host a two-hour radio show from Saturday's FanFest alongside Strom from 5-7 p.m. It'll be available on NewsRadio 610 WIOD and the Marlins Radio Network social media accounts.

You can hear McMullen's game broadcasts locally in South Florida this season on FOX Sports 940 AM or stream them from anywhere via the MLB app. McMullen will be on the call for all 30 Marlins spring training games, beginning with the February 22 Grapefruit League opener against the St. Louis Cardinals.

My prediction was off then. I’m convinced now that it’s going to be a jersey retirement of Mr. Marlin.

What do you know? Another white guy in a booth. I think Kelly Saco was perfect for a job like that. Call the game in both English and Spanish.

I love the McMullen hire. But you are correct. Saco has earned that spot.
