Georgia Tame opened the final day of this year's Equerry Bolesworth International Horse Show by continuing her rich vein of form.
The Sussex rider had already claimed one victory and a runner-up finish with Z7 Canya Dance, going into Sunday's AW Jenkinson Forest Products four-star 1.40metre table C class.
And they came up trumps again, jumping clear in a time of 52.64 seconds to win by more than half a second from Louise Simpson and Fiona V/H Lemmenshof.
Nigel Coupe and Jubilee III finished third, with Ireland's David Simpson and Gurtera Cara Drubh taking fourth place.
Georgia is based at Irish star Shane Breen's Hickstead yard, and she again underlined a prolific partnership she is forging with her eight-year-old mare.
"She is jumping great at the moment," Georgia said. "Speed classes see her in her element.
"I thought maybe someone could beat me. Matt Sampson was actually faster, but he had a fence down.
"My horse's canter is so quick, and even though she doesn't have the biggest stride, she still covers the ground just as fast as a horse with big strides. She is just naturally fast.
"She has been great all week. We've had two firsts and a second this week, so I couldn't be happier with her."
