Trained by Willie Mullins and ridden by Ruby Walsh, the nine-year-old turned on the class to complete a 16th Grade One success, heading home another Mullins horse, Thousand Stars, by a comprehensive seven lengths. Cheltenham runner-up Rock On Ruby took third place having led the race coming around the home turn but the 1-4 favourite reeled in the leaders to win in impressive style.
Victory continues a remarkable year for Hurricane Fly, who became the first horse for 38 years to regain the Champion Hurdle title at Cheltenham.
"He did a fantastic bit of work last Saturday and he proved it again today," said Mullins afterwards. "He has done everything nice and everything went according to plan.
"Rock On Ruby tried to unsettle things coming round the last bend, but Ruby was cool and calm on our fellow."
