Haziyna left behind her form at two to sluice up in the Leopardstown Family Fund Racedays Handicap.
The success for the Halling filly brought up a double for owner His Highness the Aga Khan, trainer John Oxx and rider Johnny Murtagh after the opening race win of Mesariya
Oxx remarked: "She'll get hammered for that! We'll see what the handicapper does now and we'll go for another handicap.
"We liked her last year but she ran very ordinary. She'll probably improve over time and she liked that ground which all horses apart from mudlarks would like.
"I was counting the pounds that she'd get coming up the straight."
He then joked: "I'm not sure if Johnny learned anything when he was away from me."
