Key contenders in the 2017 Breeders' Cup Turf Sprint

LADY AURELIA, by Scat Daddy

Last 3 Beyers: 97-N/A-N/A

* Has won 5 of 7 career starts, is undefeated in the U.S., and undefeated when racing with Lasix, as she will again in the Turf Sprint.

* She will reunite with John Velazquez, with whom she is perfect in two starts, including in the Giant’s Causeway at Keeneland earlier this year.

MARSHA, by Acclamation

Last 3 Beyers: N/A-N/A-N/A

* Defeated Lady Aurelia in their most recent encounter but may be at a disadvantage in the rematch having to race around a turn for the first time in her career.

* She won the Prix de l’Abbaye over firm turf a year ago at Longchamp.

DISCO PARTNER, by Disco Rico

Last 3 Beyers: 100-91-105

* Owns the second-highest Beyer Speed Figure in the field, behind only stablemate Pure Sensation, for the 109 he received for his world record this spring in the Grade 3 Jaipur at Belmont Park.

* The distance is a question mark as he’s never competed at as short as five furlongs in 20 career starts, although he did win the Troy Stakes going 5 1/2 furlongs during the summer of 2016 at Saratoga.

PURE SENSATION, by Zensational

Last 3 Beyers: 93-87-110

* Might benefit from the relative lack of early speed in the field and does own the highest Beyer Speed Figure of this group, a 110 earned for his 5 ¾-length triumph in the Grade 3 Parx Dash early this summer.

* May have run one of his best races in defeat a year ago when finishing third trying to stretch his speed to 6 1/2 furlongs over the tricky downhill course at Santa Anita in the Turf Sprint.

HOLDING GOLD, by Lonhro

Last 3 Beyers: 86-105-107

* Finished just a length behind Disco Partner despite a wide trip in the Jaipur, for which he received a career-best 107 Beyer Figure.

* Defeated Green Mask, arguably the best of this division until suffering a career-ending injury this summer at Saratoga, when rallying to a neck decision in the Grade 2 Shakertown at Keeneland in his 2017 debut.
