LOUISVILLE, Ky. (AP) — Thorpedo Anna capped her biggest victory with one impressive burst.

The filly went wire to wire in the 150th Kentucky Oaks on Friday, pulling away from a charging Just F Y I to win by 4 3/4 lengths in the slop at Churchill Downs.

Thorpedo Anna’s quick splits in her longest race over a muddy surface made it even better for trainer Kenny McPeek.

“I felt really confident, even the first half-mile,” McPeek said, crediting breeder and co-owner Judy Hicks. “She’s just fast. Judy’s bred a beautiful filly here, and she’s got gear on top of gear.”

The dark brown horse was briefly the top choice before going off at 4-1 odds and staking her claim right away in the $1.5 million marquee race for 3-year-old fillies. She led by at least a length over Fiona’s Magic with Ways and Means and Into Champagne in the mix heading into the far turn.
