Trees Valley and Donagh Meyler made full use of their opportunities to take the mares' maiden hurdle in Tramore.
The first reserve got in as No Memory was a non runner and Meyler came in for the ride.
The seven-year-old mare got a dream passage along the inner to dispute at the second last.
She was soon ridden by Meyler to take a narrow lead at the last from Lady Rocco and jumped it the better of the pair.
The 100/30 joint favourite stayed on and pulled out that bit more in the closing stages to win by three quarters of a length.
Lady Rocco finished second at 20/1. Milalee was eight lengths further away at 25/1.
Trainer Liam Burke said: "She ran well in Cork the last day but got hampered up the straight, she didn't get a clear run and would have finished closer.
"She is in again on Sunday here and she'll run. It's hard enough to get into races and she was lucky to get in today.
"She won a point-to-point at Lismore but had been disappointing all her life until now. It's only this year that she seems to be someway right in herself. I always thought a good bit of her but she just disappointed."
