MLB, Seattle Mariners, San Francisco Giants, St. Louis Cardinals, New York Yankees, Chicago Cubs

 

The home run is one of the most exhilarating plays in baseball. Homers showcase a player's power and skill. They can pump up or deflate a crowd and change the dynamic of a game in an instant.

Over the years, several Major League Baseball players have amassed impressive home run totals in a single season. Barry Bonds holds the MLB record for the most homers in a campaign, with 73 in 2001. Bonds also owns the record for the most career home runs, with 762.

Cal "Big Dumper" Raleigh of the Seattle Mariners led the league in home runs during the 2025 MLB regular season. On August 10, he joined Ken Griffey Jr. as the only Mariners players to hit 45 home runs in a season. On August 15, he became the first player to reach the 100-RBI mark, with his 46th home run of the season. On August 25, he became the first player to hit 50 home runs in the 2025 season. With his 55th homer on September 16, he surpassed Mickey Mantle's record for the most home runs by a switch hitter in a single season. On September 20, he hit his 57th home run to surpass Griffey Jr.'s single-season franchise record for home runs with the Mariners. On September 24, he joined the prestigious group of MLB players with 60 home runs in a single season.
