The Big Dumper dinger tracker has hit another massive milestone.
Cal Raleigh set the MLB single-season record for most home runs by a catcher after hitting his league-leading 48th and 49th home runs of 2025 in the Seattle Mariners’ 11-4 win over the Athletics at T-Mobile Park on Sunday, Aug. 24.
The previous single-season mark for catchers had been owned by Salvador Perez, who mashed 48 home runs for the Kansas City Royals in 2021.
Raleigh tied Perez with a first-inning 448-foot blast off of Athletics lefty Jacob Lopez that was Big Dumper’s longest home run of the season and furthest of his career while batting from the right side of the plate. An inning later, Raleigh set the record for catchers with another homer off Lopez.
The Big Dumper’s dingers were also vital to the Mariners’ quest to win the AL West, as the victory moved Seattle to within two games of first place in the division behind the Houston Astros, who were defeated by the Baltimore Orioles on Sunday.
Next possible home run milestones for Cal Raleigh
Raleigh — the 2025 Home Run Derby winner — is within striking distance of the single-season record for most home runs hit by a switch hitter.
Mickey Mantle set that standard with 54 home runs during the 1961 season; the same year his New York Yankees teammate Roger Maris broke Babe Ruth’s single-season home run record.
Raleigh also is seven home runs away from matching Ken Griffey Jr.’s Mariners record — which he set twice — by hitting 56 home runs in 1997 and 1998.
