Having already taken out the Arkle with Un De Sceaux and saddled Hurricane Fly to land a fifth Irish Champion Hurdle, Willie Mullins hit the target once more as Outlander clinched Grade Two honours in the Nathaniel Lacy & Partners Solicitors Novice Hurdle.
Narrowly beaten by the reopposing Martello Tower over three miles at Limerick last month, Outlander (5-1) enjoyed coming back in trip under Paul Townend.
The seven-year-old cruised through the two-and-a-half-mile contest and was still on the bridle approaching the final flight.
He soon opened up once given his head, passing the post three and a quarter lengths ahead of Martello Tower to give the champion trainer a fourth successive victory in the race.
The winner's stablemate Killultagh Vic was third, with No More Heroes disappointing in fifth.
Mullins said: "He was beaten by a better horse at Limerick. We rode him differently today as he was a bit keen at Christmas and we said we'd settle him in.
"He's back on track to being the horse we thought he'd be as a triple bumper winner. I told Paul to ride him like a good horse.
"The Neptune would be my immediate thought. He seems to have plenty of toe and in the Supreme Novices' you need to stay. We'll see over the next few weeks."
