A pair of Breeders’ Cup Challenge Series qualifiers served as the highlights of a graded stakes triple on the first Sunday of Keeneland’s autumn meet.

If Fully Subscribed runs anywhere close to her effort in the Aug. 29 Personal Ensign (G1) in the $650,000 Spinster (G1) at Keeneland on Sunday, it’s doubtful she can be beaten.

Opening week of the Keeneland fall meet wrapped up on Sunday with a trio of stakes, including two “Win and You’re In” qualifiers to the Oct. 31-Nov. 1 Breeders’ Cup.

Racing fans won't have to wait until the Nov. 1 Breeders' Cup Distaff (G1) to see a clash of the generations among fillies and mares.

Reigning Breeders’ Cup Distaff (G1) winner Idiomatic earned a fees-paid berth back to the Breeders’ Cup when dominating Sunday’s $600,000 Spinster (G1) at Keeneland for the second straight year.

Idiomatic continued her giant year with a decisive victory in Sunday’s Spinster (G1) at Keeneland, cementing her status as the favorite for the 2023 Breeders’ Cup Distaff (G1).

About four hours after younger stablemate Nest flaunted her class in the Beldame (G2), older star Malathaat likewise obliged as the odds-on favorite in Sunday’s Spinster (G1) at Keeneland.

Leading older mare Letruska racked up her fifth straight win – and fourth consecutive Breeders’ Cup Challenge event – in Sunday’s Spinster S. (G1) at Keeneland.
