Voy Por Ustedes (5-1) caused a major upset by beating Master Minded in the John Smith's Melling Chase at Aintree.

The battle of the last two heroes of the Queen Mother Champion Chase was won by the Alan King-trained runner, 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.
