The Listener jumped his rivals into the ground for a pillar-to-post victory in the Grade One Lexus Chase at Leopardstown this afternoon.
Ridden for the first time by Daryl Jacob, the grey was full of enthusiasm in the testing conditions and never looked like being headed.
Beef Or Salmon, bidding for a fourth success in the race, stayed on for second eight lengths in arrears, while Gold Cup winner War Of Attrition ran a sound race to finish third.
Jacob set only a steady gallop on the seven-year-old, but he was gaining lengths at every fence.
Tony McCoy settled L'Ami in second and he travelled well for a long way only to weaken in the closing stages.
As the main protagonists moved up to challenge on the home turn, Jacob looked over his shoulder with an air of confidence.
Another fine leap at the last sealed the win as Beef Or Salmon ran his usual sound race to chase him home.
Mouse Morris will also be pleased with War Of Attrition, who ran with credit on ground that will not have been to his liking.
