The Black Corton and Bryony Frost partnership came up trumps once again with an impressive performance in the Sodexo Reynoldstown Novices' Chase at Ascot.
Since teaming up together over fences in July, the pair have faced the starter eight times together and only met with defeat once, at Newbury in December.
As Black Corton had won the Grade One Kauto Star Novices' Chase, he was giving weight away to his three rivals and turning into the straight, he looked a little vulnerable.
Ms Parfois and Mount Mews both appeared to be going every bit as well, but Black Corton had been saved for a finishing burst and without visibly asking for too much, Frost kicked clear and the race was soon over.
The 10-11 favourite, trained by Paul Nicholls, never put a foot wrong as Frost continued her incredible run of big-race Saturday successes.
Black Corton was cut from 16-1 to 10-1 by Betfair for the RSA Insurance Novices' Chase at Cheltenham next month.
