Top trainer Fred Kersley dominated the Sheila Gwynne Classic (1400m) when he trained a quinella in the $100,000 Listed race at Ascot on Saturday.
Completing the second-leg of a feature double, Mizlecki stormed home from third on the corner for jockey Jerry Noske and scored by 1 ½ lengths.
Stable mate Necklet, who snatched the lead early in the straight, held on for second, ahead of improving Kalgoorlie-based galloper Swift Sis.
Favourite Royal Missile’s hopes for victory were dashed when he was trapped wide throughout, the $3 fancy finished sixth.
Mizlecki, a daughter of Lope De Vega, has two black-type wins from nine starts after her victory in the Listed Raconteur Stakes (1500m) two weeks ago.
Kersley said Mizlecki and Necklet were both progressive types and displaying good signs early in their careers.
“They are both pretty new and haven’t had many starts,” Kersley said.
“They are creeping up in the handicaps, but you take it as it comes.
“Black-type is interesting from a breeders’ point of view and that’s where you go.
“They are the good races and that’s what you are here for.”
Noske said she is relishing her association with the Kersley stable and the opportunity to partner Mizlecki.
“I have only just starting riding for Mr Kersley recently and I am very lucky,” Noske said.
“He has always been a great supporter and I’m lucky to get this one at the moment.”
Noske has a perfect record on Mizlecki after steering her to victory in the Raconteur Stakes.
“She is putting it together in her head and is going from strength to strength,” Noske said.
