Aintree: Voy Por Ustedes caused a major upset by beating Master Minded in the John Smith's Melling Chase at Aintree this afternoon.
The battle of the last two heroes of the Queen Mother Champion Chase was won by the Alan King-trained 5-1 shot, who relished the extra half-mile.
Storming into the lead between the last two fences under Robert Thornton, Voy Por Ustedes went clear on the run to the line to win by 18 lengths from the 2-5 favourite.
Tamarinbleu was 18 lengths further back in third.
As expected Tamarinbleu took the field of six along in the early stages from Newmill and Master Minded.
Turning for home with three fences to jump, Voy Por Ustedes took a narrow lead but Master Minded joined him only to lose some momentum over the second-last.
That gave Voy Por Ustedes his big chance and he powered away to lower Master Minded's colours.
King said: "You'd probably say Master Minded is a proper two-miler and we've always felt Voy Por might be better over further and I think that's been proved today.
"I'm so pleased for the horse, he's been very special to me all the way through.
"He's very tough and I think we've probably been asking him to do the impossible as he needs a trip.
"We'll go home and think about it but to my mind we'll continue over two and a half miles next year and probably look at the King George."
Pettifour made up for Battlecry's narrow defeat in the day's opener as trainer Nigel Twiston-Davies and PJ Brennan combined to win the Citroen C5 Sefton Novices' Hurdle.
Sent off at 16-1, the six-year-old was always near the head of affairs in the extended three-mile test and settled down to scrap out the result with runner-up Gone To Lunch (8-1) soon after entering the straight.
The Tother One cruised into a challenging position but weakened into third late on, leaving Pettifour to get the better of Gone To Lunch by a neck.
Andrew Tinkler had a winning spare ride when replacing Mick Fitzgerald on Oedipe (20-1) in the totepool Handicap Chase.
Always prominent, Nicky Henderson's charge kicked for home a long way out and had enough left in the tank to hold Three Mirrors by three and three-quarter lengths. The first two pulled 21 lengths clear of Alderburn, with Rayshan fourth.
Supporters of the 5-1 favourite Mister Top Notch lost their money when the Irish raider fell at the sixth fence.
