Fox Norton (5-2) has been a model of consistency since joining the Tizzard team and after finishing a close second to Special Tiara in the Queen Mother Champion Chase he lifted the Melling Chase at Aintree.

He was not inconvenienced by the return to two miles, with the strong pace set by Un De Sceaux and Rock The World playing to his strengths.

Fox Norton got home by a length and three-quarters from the 10-11 favourite. Last season's winner God's Own was not disgraced in third place, just half a length away, and might have finished closer but for a mistake at the last.

Power, who won the Cheltenham Gold Cup on Sizing John in the same colours of Alan and Ann Potts, said: "It's been an unbelievable season and getting a Grade One at Punchestown as well for Mr and Mrs Potts - it's fantastic.

"He was flat to the boards the whole way. I didn't want to give Un De Sceaux too much rope. Just because of that I was flat out the whole way and he made one or two little mistakes, but once we turned in I knew I would pick him up.

"Two miles is sharp enough for him. He's a very relaxed horse. He'll have no bother going further."
