Seattle Mariners catcher Cal Raleigh broke Mickey Mantle's record for most home runs in a single season by a switch hitter, hitting his 55th homer against the Kansas City Royals. He then hit another, tying Ken Griffey Jr.'s Mariners' single-season record of 56. Raleigh, who also won this year's Home Run Derby, now leads MLB in home runs with 56, surpassing Salvador Perez's catcher record and with a chance to break Aaron Judge's AL record before season's end.
