Joseph O'Brien went clear at the top of the jockeys' championship after riding Chamonix to victory for his father, Aidan, at Killarney.

The red-hot rider, winner of the apprentice title last term, was remarkably registering his 11th success in the space of a week and had little trouble justifying 4-5 favouritism on Chamonix.

The Galileo colt stepped up considerably on the form of his debut sixth at Leopardstown to run out a ready winner of the Sika Signs Maiden.

After settling on the shoulder of the leader, Clondaw Warrior for most of the race, he forged into a clear lead passing the two-pole and kept up a relentless gallop to beat Bob Lingo by 12 lengths.

The winning rider was denied a double on the night when Beach Of Falesa could manage only fourth in the Irish Stallion Farms EBF Fillies Handicap.

The combination of a busy recent schedule and a 10lb penalty proved too much for the hat-trick seeking filly, as the Andrew Oliver-trained Jazz Girl (20-1) caused an upset by beating Queens Visit by half a length in the hands of Gary Carroll.

Ben Curtis got another fine tune out of Pat Martin's California Rose (11-2) in the Killarney Oils Ltd. Handicap.

The same partnership had combined to good effect at Bellewstown earlier in the month and the filly defied her revised rating with a two-length defeat of Money Spider

Jim Dreaper's Go All The Way landed some hefty bets in the John Buckley Auctioneers Beginners Chase.

The 11-10 favourite jumped his rivals silly on his way to an 11-length triumph and provided Davy Russell with his fourth winner of the week, from as many rides.

The Ladbrokes Handicap Chase went to 16-1 shot Black Mac who made every yard under Paul Carberry, while Black Benny (6-1) won the Bunkers Bar Killorglin Handicap Hurdle in the hands of Denis Hogan.
