Leading American hopefuls Sistercharlie and Fourstar Crook drew posts six and one for Saturday's Breeders' Cup Filly and Mare Turf at Churchill Downs - a race in Chad Brown entered five horses among the full field of 14. In addition to Sistercharlie and Fourstar Crook, his other entrants include Thais, A Raving Beauty and Santa Monica.

At 1 3/8 miles, the first of three turns in this race on the Churchill turf arrives in just 485 feet, according to the 2018 Breeder's Cup Horsemen's Guide. This gives jockeys a limited amount to secure position before the field leaves the backstretch.

Historically, outside posts have been a disadvantage over the 1 3/8-mile distance at Churchill Downs from a limited sample - though a wet turf course could negate this effect. Heavy rain is expected midweek for the Louisville area.

In querying Daily Racing Form post-position database, which dates back to 1991, there was not a single winner over that stretch at Churchill that started from beyond post 10 going 1 3/8 miles on turf, though the sample size was small. Posts 11-14 were a collective 0 for 17, and horses from posts 9-10 also struggled, going 3 for 66.
