made every yard of the running to lift the Sky Bet Peter Marsh Chase at Haydock.
Trained by Sara Bradstock and ridden by Jack Tudor, Mr Vango was last seen winning the three-and-a-half-mile London National at Sandown last month and with his stamina assured, connections were eager to make it a real test.
Bill Baxter was an early casualty when unshipping his rider on the first circuit and Royale Pagaille, who was bidding for a third win in the race under a top weight of 12st, made a couple of notable mistakes that put paid to his chances and saw jockey Charlie Deutsch pull him up at the top of the home straight.
While others wilted under the testing conditions, Mr Vango and former Welsh National winner Iwilldoit thrived over the extended three miles and one furlong on soft ground, battling it out over the final two fences.
However, Mr Vango pulled ahead before the final obstacle and maintained his gallop to the line, registering a three-length victory at 4-1, with Iwilldoit just holding off the determined late spurt of Richmond Lake to take second.
