Cal Raleigh is re-writing the record books once again—this time for the Mariners.
Raleigh hit his 57th home run of the season off Astros pitcher Framber Valdez on Saturday, and now passes Mariners legend Ken Griffey Jr. for the franchise's single-season home run record.

Griffey Jr., a Hall of Famer and 13-time All-Star that played for Seattle from 1989-99 and 2009-10, hit 56 home runs in a season for the Mariners in both 1997 and 1998. Now, Raleigh has passed that mark and his 57 long balls are tied for the 17th-most in a single season by any player in MLB history.
Earlier this week, Raleigh tied Griffey Jr.'s record and also broke Mickey Mantle's record for the most home runs in a single season by a switch-hitter. Mantle hit 54 home runs in 1961 to set the record, and over 60 years later, Raleigh has broken that mark and become the second switch-hitter to surpass 50 home runs in a season.
Along with these records, Raleigh previously broke Salvador Perez's record for most home runs in a season by a catcher. Perez hit 48 home runs in 2021, and Raleigh surpassed that nearly a month ago.
