HAYDOCK PARK (AFP) - English steeplechaser Kauto Star added to his legend here on Saturday as the two-time Cheltenham Gold Cup champion showed reports of his decline were premature by winning the Betfair Chase for the fourth time. Paul Nicholls-trained gelding - the only horse to have regained the Gold Cup trophy - put on a remarkable front-running performance and jumped immaculately to put present Cheltenham Gold Cup champion Long Run. Kauto Star returned under Irish rider Ruby Walsh to a rousing reception and cries of 'Hip Hip Hurrah' rang round the winners enclosure.
