Willie Mullins saddled a double in Leopardstown when Magic McColgan kept on best in the mares' bumper.
The even-money favourite lost her place approaching the straight and Neon Diamond got the first run on her inside the final quarter of a mile.
Patrick Mullins conjured more from the favourite, though, and she rallied to lead a furlong down.
From there, she wasn't going to be beaten as she stuck to her task to score by a length and a-half from Neon Diamond (4/1). Tell Me This (22/1) was well adrift of the front pair in third.
“It was a nice performance and she's improved nicely from Christmas,”
said trainer Mullins.
“I'd imagine we'll probably keep her for Punchestown, for the listed mares bumpers, unless there is another one in between. She's a full-sister to Tornado Flyer.”
Mullins also won the beginners' chase with Horantzau D'airy
