Offaly's Darragh Kenny enjoyed a superb victory in Sunday's Longines FEI World Cup Grand Prix at Deeridge in Florida.

Riding the Ann Thompson-owned 10-year-old gelding Classic Dream, Kenny came out on top after a brilliant performance to take the winners prize of over $70,000 along with some valuable World Cup points.

Clear rounds were at a premium over the first round course designed by Tipperary's Alan Wade, and as Kenny entered the arena as second last to go, just two clear rounds were on the board.

The world number eight showed his class and produced a foot-perfect clear to give him the best draw as last to go of the trio that would battle for the winners prize against the clock.

Both of the combinations who went before Kenny in the jump-off completed double clear rounds, with Brazil’s Cassio Rivetti holding the lead with Bacara d’Archonfosse as the Irish rider entered the arena as last to go.

Rivetti’s time of 38.29 looked impressive, however, Kenny amazingly knocked over a second and-a-half off the target, crossing the line clear in 36.70 to take victory.

Rivetti took runner-up spot while American rider Devin Ryan finished third with the only other fault-free performance aboard Eddie Blue in a time of 39.00.

Speaking afterwards, a delighted Kenny was full of praise for his winning mount.

"He [Classic Dream] is a green horse in jump-off’s but he is an incredible jumper and I just went as fast as I could. He felt great and was trying hard – he was fantastic," said Kenny.

World Cup action returns to Europe next weekend at Bordeaux in France where Ireland will be represented by Michael G Duffy, Denis Lynch and Mark McAuley.
