Jockey Keith Asmussen recorded his 64th career victory in Saturday's opener at Oaklawn, eclipsing the total of his father, Hall of Fame trainer Steve Asmussen, during his riding career.
Keith Asmussen, fittingly, reached the milestone on a horse trained by his father, Hern, who won the 1 1/16-mile claiming race.
“Couldn't be more excited for today and the rest of the meet,” Keith Asmussen said.
Steve Asmussen rode 63 winners in 1982-1984, according to Equibase. Asmussen turned to training after he became too heavy to ride.
Keith Asmussen, 25, launched his full-time riding career in late 2022 after earning a master's degree in professional accounting earlier in the year from the University of Texas' McCombs School of Business.
Asmussen's younger brother, Erik, 21, made his Oaklawn riding debut in Saturday's first race and finished sixth aboard What a Country for his father.
“It was awesome to get to ride with my brother,” Keith Asmussen added.
