Willie McCreery's Fiesolana showed tremendous guts to hold off Along Came Casey in the final furlong to win the Irish Stallion Farms EBF Brownstown Stakes at Fairyhouse.
The four-year-old had won her last two starts, including the Ballyogan Stakes at Leopardstown, but was penalised for that win.
Always to the fore under Billy Lee she had some highly-touted rivals off the bridle two furlongs out but Dermot Weld's Along Came Casey looked poised to pounce.
Try as Pat Smullen might, however, despite closing in the final strides Fiesolana won by a head.
Aidan O'Brien's Snow Queen made late headway into third with Lily's Angel and Hint Of A Tint also close up in behind, but William Haggas' British raider Sentaril faded to finish unplaced.
Lee said: "Everything went very easy, she travelled well and picked up well.
"I thought Pat had me, but she had a bit left in the locker. There wasn't much pace early on so I was able to get over from her wide draw. She's easy to do anything with.
"She's won under a penalty and with a bit in hand, she could be a good performer later in the season."
McCreery said: "She's just a non-nonsense mare. She keeps doing it and that's another step up on ground that she wouldn't be keen on.
"I said to Billy to take his time on her and he gave her a lovely ride. He said she was doing nothing in front and when the other horse came to her she went on again.
"I've not got any future plan in mind for her."
Earlier on the card Weld's Simple Love made a very pleasing winning debut in the Irish Stallion Farms EBF Median Auction Maiden.
"She's a lovely filly. She's put a few nice pieces of work together and she worked on grass the other morning for the first time," said Weld.
"She's laidback and when he asked her she answered the call."
