Andrew Nicholson took control at the Kentucky three-day event this morning (NZT), after two brilliant cross country rounds put him into first and second places.
The world No 1 eventer sits on his dressage scores of 38 penalty points aboard Quimbo and 40.8 on Calico Joe after a pair of clear runs.
Nicholson is chasing not just victory at Kentucky but also the chance to earn the US$350,000 Rolex Grand Slam, for a rider who manages to win Burghley, Badminton and Kentucky in succession. With Burghley already in the bag, Nicholson needs victory at Kentucky followed by Badminton next weekend.
The 51-year-old had plenty of praise for Quimbo, rating the cross country in their first four-star start together as probably his ``most exciting ride ever''.
"He is unbelievable,'' he said. "For the first time at this level, he is just amazing.''
