Sackville goes for Charlie Hall Sackville will put his Cheltenham Gold Cup credentials on the line when lining up for the Peterhouse Group Charlie Hall Chase at Wetherby tomorrow.Frances Crowley`s gelding was only third on his return at Punchestown last month over an inadequate two miles.But he went eight races unbeaten in a fantastic novice season which had set him out as an outstanding prospect.A total of 10 runners have been declared for the Stg#50,000 contest.They include the Paul Nicholls-trained Shotgun Willy, who represents the stable instead of ex-Cheltenham Gold Cup winner See More Business, who won the race last year.The other eight runners are Sleeping Night (trained by Mary Reveley), Flying Instructor (Paul Webber), Legal Right (Jonjo O` Neill), Streamstown (Ferdy Murphy), Beau (Nigel Twiston-Davies), Folly Road (David Williams), Lord Noelie (Henrietta Knight) and Scotmail Boy (Howard Johnson).The Grade Two race is run over three miles and a furlong and is one of the key early season chasing highlights.
