Cal Raleigh took over as the Mariners all-time, single-season home run leader when he hit his 57th home run on Sept. 20, 2025, and then he added another the next game. He is not the only player in recent years to take the franchise record for himself, however.
Here is every one of MLB's 30 teams and their franchise leader in home runs, organized by the most – Barry Bonds' MLB record 2001 – to the least. Of the 30 clubs, eight have yet to produce a 50-homer season.
