Kilkenny’s Richie Moloney scored one of his biggest wins of his career when he guided Carrabis Z to victory at the $300,000 Hampton Classic Grand Prix at Bridgehampton in New York.

Moloney and the 13-year-old stallion were one of five combinations to make it into the second round jump-off.

Drawn fourth to go against the clock, the pair produced a stunning clear round in 39.57 seconds to push America’s Charlie Jacobs and Cassinja S into second.

Andrew Welles and Brindis Bogibo, also representing the US, couldn’t beat the Irish rider’s time and had to settle for third place.

The Hampton Classic has been a lucky show for Moloney in the past, having finished third in the same competition in 2014 behind Irish winner Kevin Babington.

Tipperary-born Babington finished ninth in tonight’s competition with the 11-year-old mare Shorapur.
