After 25/1 and 33/1 winners on the card, it was the turn of 16/1 shot Baby Dinnis to rip up the form book in the mile handicap at Dundalk.
From mid-division, Ross Coakley brought the three-year-old filly down the centre of the track as the field turned into the home straight.
She really started to motor from the two pole and picked up the lead a furlong and a half out. She forged on in the final furlong and was able to hold 7/4 favourite Vocal Warm Up on the rail by a length and three quarters.
"I'm delighted with her. We've always liked her," handler Denis Cullen said.
"The step up to a mile helped. Things were just happening a bit quick over seven and she needed to learn how to race.
"At Gowran the last day she got caught up in the trouble at the start and she was a bit of an unknown quantity coming here.
"She did it well and is a nice filly. We'll look for something similar.
"Fran (Berry) rode her up here the last time and said that she hits the ground hard and mightn't just handle the all-weather, but this was the only race for her after Gowran didn't work out."
