Richard Hughes claims maiden Breeders' Cup success
Chriselliam, trained by Charlie Hills and ridden by Richard Hughes, was tremendously impressive in winning the Breeders' Cup Juvenile Fillies Turf at Santa Anita, giving Hughes his first Breeders' Cup success.
A surprise 28-1 winner of the Fillies' Mile at Newmarket, the daughter of Iffraaj showed that Group One success to be fluke, travelling smoothly all the way and rocketing clear once Hughes pressed the button.
Testa Rossi was second but the winner was never in any danger, looking better the further she went.
It was a first all round as a maiden Breeders' Cup victory for Hills and Hughes, and Chriselliam is part-owned by former jockey Willie Carson, who endured Breeders' Cup heartache in 1990 with Dayjur.
Ealier on the card, Outstrip, trained in Newmarket for Godolphin by Charlie Appleby and ridden by Mike Smith, narrowly beat Aidan O'Brien's Giovanni Boldini to win the Breeders' Cup Juvenile Turf.
Bobby's Kitten set a blistering early pace and swung into the straight still with an advantage but with Ryan Moore and Giovanni Boldini in hot pursuit.
Dundalk winner Giovanni Boldini got the better of Bobby's Kitten, but Mike Smith was all the while winding Dewhurst third Outstrip up and once engaging top gear he mowed the front two down close home for a scintillating success.
