Crystal D'Ainay was cut across the board for victory at the Cheltenham Festival after winning Saturday's betfair.com Rendlesham Hurdle.

Under Robert Thornton, Crystal D'Ainay recorded a comfortable victory at Kempton, seeing off Monet's Garden by three and a half lengths with pre-race favourite Royal Rosa a further six lengths back.

The Alan King-trained horse was subsequently cut for glory in the Ladbrokes World Hurdle, formerly the Stayers' Hurdle, at Cheltenham next month.

Ladbrokes and VC Bet cut Crystal D'Ainay to 5/1 joint-second favourite from 8/1 for the World Hurdle, with Paddy Power initially longest at 7/1 but then going 6s. Coral go 9/2 from 7/1.

Many layers removed Royal Rosa and Patriarch Express from their betting, the former having returned to the unsaddling enclosure looking decidedly sore.

Former winner Baracouda remains a hot favourite for the World Hurdle - a best price of 5/4 is currently on offer.

Hills trimmed Baracouda in to evens from that price on Saturday.
