Coreczka brought up her seventh career victory with a powerful finishing kick in Division One of the seven-furlong handicap.
Every one of her wins has come on sand - six at Dundlak and one at Laytown beach.
The six-year-old raced widest of all 12 runners approaching the final quarter of a mile.
She began to pick up for Oisin Orr and swept to the front at the furlong pole and was ridden out to win by three parts of a length.
She was well backed at the track from 8/1 to 5/1. Silk Cravat the 10/3 favourite, followed her home with Sheisdiesel third at 25/1.
“She's brilliant for me, for a small yard, and I don't think I'll ever get another one like her,” trainer Claire Cannon said.
“She's been on the go a bit over the summer so she'll maybe have a gap somewhere along the line rather than going all winter. We'll see how she is when we get her home.
“I'll need to search harder to find another one before she goes.”
