The Willie Mullins trained Dicosimo ran out an easy winner of the feature at Limerick, the Listed Irish Independent Hurdle.
The French import won on his debut for Mullins at Gowran in January before finishing eighth in the Triumph Hurdle at Cheltenham in March.
He was last seen finishing fourth in a Grade 3 at Fairyhouse in April, and he was sent off the 5/4 favourite today under Danny Mullins.
Sent straight to the front he made all and despite being pressed before the straight, he eased clear from the second last, going on to score by ten lengths in the colours of the Ricci's. Theophilus (9/2) finished second under Andrew Lynch for Des McDonogh, while Bamako Moriviere was a further two and a half lengths back in third under David Mullins.
Danny Mullins said afterwards: "I was always confident and able to get a breather into him coming down the hill. I wanted to fill up the tank before going again and he was good.
"His form flattened out maybe last spring but hopefully this year he'll keep it going and there's no reason he won't."
