"She’s a boss mare — she runs the stable and is in charge and very confident in herself,” said the US rider after their CSI5* grand prix victory.

The US rider piloted the good mare and "alpha horse" Greya to another massive payday under the ‘Saturday Night Lights’ at WEF.

The victory came aboard the mare Greya, deflecting a strong challenge from Christian Kukuk and his Olympic gold medal partner Checker 47.

The Holiday & Horses CSI4* week at Wellington International concluded with the US rider scoring in the feature Grand Prix on Sunday.

Kent Farrington piloted the speedy mare to win the Longines FEI Jumping World Cup; Erynn Ballard was 10th with De Flor 111 Z Santa Rosa.

The action included the Rolex Grand Prix, Loire Region Derby and Nations' Cup Barrière as selectors get closer to picking Olympic teams.

Canada's Sam Walker places fourth in the class riding Equine America Ivanhoe GPH in a field of 44 over Catsy Cruz's track.
