Since 1988, the first of eight occasions Churchill has previously played host to the event, only four Derby alumni have ever returned to the Louisville track to register a Breeders' Cup win.
There were two, in fact, on that cold, wet day in 1988. Alysheba, winner of the 1987 Derby, became North America's all-time leading money winner with a victory in the Classic (G1). Kicking off the action that afternoon was Gulch, who rallied to win the Sprint (G1) having run sixth to Alysheba in the Run for the Roses.
Years later, War Chant (2000) and Court Vision (2011) both captured the Mile (G1) on turf after previously running in the Derby. War Chant had run ninth to Fusaichi Pegasus in the 2000 classic, while Court Vision had run 13th to Big Brown in 2008.
Half of the eight Derby alumni competing in this year's Breeders' Cup will square off in the $6 million Classic over the Derby distance of 1 1/4 miles.
Thunder Snow, who notably bucked and was pulled up soon after the start of the 2017 Derby, will again break from an inside post in the Classic. Another veteran of that Derby, won by Always Dreaming, is Gunnevera, who ran seventh.
With Justify retired over the summer, Mendelssohn and Lone Sailor are the only 2018 Derby alumni in this year's Classic. The well-supported Mendelssohn finished last of 20 following a rough trip, while Lone Sailor fared better in an eighth-place effort.
