LOUISVILLE, Ky. – Rusty Arnold had a very hot hand last week at Churchill. From seven starters, Arnold won a Thursday race with Cadillac Candy, then went 3 for 3 Friday with Grand Oak, Late September, and El Kabong. He capped things off Saturday by winning the Louisville Stakes with Cellist, one of his two starters in the Grade 3 turf race. “It’s nice to have a run like that because it can dry up in a hurry,” said Arnold, who saddled his first winner in 1975. :: Want to start playing with a $510 bankroll and have access to free Formulator?

Herrforth, a 28-year-old Ohio native, works as an exercise rider for Sharp. She is a graduate of the North American Riding Academy based in Lexington, Ky. Herrforth dedicated the victory to Callie Witt, who died last month at Keeneland at age 20 from injuries suffered in a morning training accident on a Sharp horse. “Callie was an amazing individual,” said Herrforth. ◗ Two stakes, both for fillies and mares, are on tap for the Memorial Day weekend at Churchill.
