Last Goodbye (12-1) provided jockey Adam Short with the biggest win of his career in the Chanelle Pharma Handicap Chase at Leopardstown.
Liz Doyle's charge looked a well-handicapped horse when scooting clear by nine lengths from Vieux Morvan.
Short's claim has now been reduced from 7lb to five.
Doyle said: "We thought he had a big race in him based on his Cheltenham run where he met loads of interference.
"Adam gave him a great ride and it will be back to Cheltenham now, but I'm not sure for which race."
Jessica Harrington wasted no time in adding to Supasundae's Irish Champion Hurdle win as Alletrix justified favouritism in the Irish Stallion Farms EBF Paddy Mullins Mares Handicap Hurdle.
Sent off at 4-1 in the colours of Champion Chase hero Special Tiara, favourite-backers never had much to worry about.
British challenger Lady Buttons travelled strongly into contention down the back straight and was in front turning for home, but Robbie Power always exuded confidence aboard Alletrix.
She survived a scruffy leap at the last to beat Barra by seven and a half lengths, with Contingency and Lady Buttons third and fourth respectively.
Harrington said: "I suppose the handicapper was right.
"She was in here and when I saw she got 125 for her next handicap, this was such a big pot and there is not a lot of her so the light weight helped.
"The bit of rain that fell (on Saturday night) helped also and she jumped like a buck, except at the last.
"She is learning and is not going near Cheltenham but will go for a mares' hurdle at Limerick and then the mares' race at the Fairyhouse Easter Festival."
