Seattle Mariners catcher Cal Raleigh has set a new Major League Baseball record for the most home runs hit in a single season by a catcher. On August 24, 2025, Raleigh hit his 48th home run, tying the previous record held by Salvador Pérez. Later that day, he hit his 49th home run, surpassing Pérez to become the catcher with the most home runs in a single season. Raleigh's achievement also includes surpassing Mickey Mantle for the most multi-homer games in a season by a primary catcher, defined as one who catches at least 75% of games. On August 26, 2025, Raleigh hit his 50th home run, making him the first catcher in MLB history to reach the 50-home run mark in a single season. His performance has positioned him as a leading candidate for the American League Most Valuable Player award. The Mariners' offensive surge accompanying Raleigh's record-breaking performance contributed to a dominant win over the Oakland Athletics.
