The American was one of three riders to produce a clear round at the Live Oak Plantation, setting up a jump-off for the podium places.

Vanderveen, riding on Bull Run's Faustino de Tili, would be the first rider to head back to the course.

She achieved a time of 45.93 seconds, laying down a strong marker for her rivals.

Fellow American Brianne Goutal finished with the second best time of 52.99, riding on horse Viva Colombia.

The podium was rounded off by Switzerland’s Beat Mändli, after he picked up two penalties on Galan S in the jump off.

The victory ensured Vanderveen would qualify for the World Cup Finals in Paris.

"It's really very surreal for me right now," said Vanderveen.

"I've always wanted to go to World Cup Finals, and this was a little bit of a last minute decision to come here and see if I could do something special today and get in.

"There were only three of us, so I figured I'd play it out fast as we could and see what happened.

"He fired for me, and he shined for me in the jump-off."

The event brought an end to the North American Jumping League season, with Mändli topping the east coast standings with 53 points.

He was followed by Americans McLain Ward and Alison Robitaille, who both scored 52 points.

The west standings were topped by Richard Spooner, with the American finishing with 60 points.

Mandy Porter and Jamie Barge completed an all-American top three on 54 and 48 points respectively.

The World Cup Final will take place in Paris from April 10 to 15.
