Sire De Grugy followed the script and brought the house down with an easy victory in the Celebration Chase at Sandown.
At the final meeting of Britain's jumps season, the biggest cheers of the afternoon were reserved for the popular Champion chaser who blitzed his five opponents in the two-mile event under Jamie Moore.
After justifying 2-7 favouritism and running out an eased-down 3-1/4 length winner from Pepite Rose, trainer Gary Moore admitted he felt the glare of the spotlight.
"I was slightly nervous today because a lot of people, some good judges among them, told me I shouldn't come here and told me to put him away because horses don't always come back in the same form after Cheltenham," Moore said.
"It shows what a great horse he is to win four Grade One chases in a season."
Sire De Grugy will now have a summer break and is expected to make his seasonal return at Chepstow in October.
The eight-year-old will then be aimed at a defence of his Champion Chase crown at Cheltenham next March.
