Last Christmas Foxrock finished third in the Grade One Lexus Steeplechase at Leopardstown but this year he proved different class in Down Royal's hunter chase.
Katie Walsh did the steering for her father Ted Walsh.
The 2/1 favourite chased the leaders Valmy Baie and Balnaslow before improving to lead at the third last.
He asserted before the final fence and drew away to score by eight lengths.
Balnaslow (10/1) and 4/1 shot Buckers Bridge completed the placings in second and third respectively.
This was a turnaround in form from Borris House where Balnaslow had beaten Foxrock in a point-to-point a fortnight ago.
Valmy Baie weakened quickly and was pulled up after five out. He was examined and found to be clinically abnormal post race.
Katie Walsh said: "He jumped well. He was very safe but he's not as quick through the air as the others.
"He had loads in the tank at the business end, he has plenty of ability.
"He's given us some great days and he's a highly-rated chaser. We were looking for a big run today and I think he delivered."
