Three years after Argentine import Blue Prize reached top form and upset the Breeders’ Cup Distaff (G1), her half-sister Blue Stripe could be on a similar trajectory.

Three stakes on the Saturday evening card at Churchill Downs produced exciting finishes with potential Breeders’ Cup implications.

Kentucky shipper Shedaresthedevil added a third Grade 1 victory to her portfolio, and a free berth to the Breeders’ Cup Distaff (G1), in Sunday’s $300,000 Clement L. Hirsch S. (G1) at Del Mar.

The only one to edge division leader Letruska this season, Shedaresthedevil is also the lone shipper in Sunday’s $300,000 Clement L. Hirsch S. (G1) at Del Mar.

Letruska was left on an easy lead in Saturday's $480,000 Ogden Phipps S. (G1) and proceeded to make her rivals pay in the "Win & You're In" qualifier for the Nov. 6 Breeders' Cup Distaff (G1) at Del Mar.

A pair of Grade 1 events, the $1 million Metropolitan H. and $500,000 Ogden Phipps S., highlight a trio of graded stakes on the main track for older horses on Saturday’s Belmont Stakes Day undercard.

Like stablemate Monomoy Girl before her, Shedaresthedevil added Friday's La Troienne to a tally that also includes the Kentucky Oaks.

The Oaklawn racing card on March 13 boasts of the Azeri S., Essex H., Temperence Hill S., and Hot Springs S.
