Sizing Europe turned in an ultra-game performance to claim the Queen Mother Champion Chase at Cheltenham.

Henry de Bromhead's 10-1 shot, last year's Arkle winner, led a long way out for Andrew Lynch and battled on bravely to hold the title holder Big Zeb (3-1).

Captain Cee Bee was third and Golden Silver next as the Irish filled the first four places.

Dual winner Master Minded lost any chance with a bad mistake at the second-last and he was eased afterwards by Ruby Walsh.

Lynch said: ‘I'm delighted and the horse jumped an awful lot better today.

‘He travelled really well and I was afraid something might just quicken past me up the straight, but he's a hardy boy.

‘Henry always said he wanted a strongly-run, two-mile race, and this is the only race all year that suits him.’

Mad Max made the early running, with Sizing Europe close up and Big Zeb and Master Minded in midfield.

Lynch took Sizing Europe to the front at the sixth fence and looked comfortable at the head of affairs.

The expected main players started to play their hands before the turn for home, but De Bromhead's nine-year-old showed he has stamina as well as speed and kept Big Zeb at bay by five lengths.

The victory capped a memorable two days for De Bromhead, who won the cross-country chase with Sizing Australia, also owned by Ann and Alan Potts, on Tuesday.
