It was her turn at Randwick on Saturday as she charged through the field to run down Leebaz and win the Japan Racing Association Plate.

"I am bald from scratching my head," Snowden said. "With these fillies what do you do? How do you turn their form around. Even today she stood in the gates and missed the start by three lengths.

"She does everything so well at home, but she doesn't bring her A game to the races. Her work is brilliant. I work all of my best horses with her. If they stay with her they are going really well.

"She has been promising so much and I've been promising them [owners] she is going to win today and she hasn't been. I am glad she did today."

It was Gypsy Diamond's 10th run for Snowden and her first win for him. It was her first victory in a year when she won the Carbine Club Stakes during The Championship and backed up by being runner-up in the Queen Of The Turf.

She will head back to part-owner Ron Finemore's home for the Wagga Cup on May 1.

"I have won it before and always like to go back. She is a mare that once she strikes form she can put a couple of good ones together," Finemore said.

It a muddling speed, Gypsy Diamond got back in the field and was able to go through her gear for Sam Clipperton, who punched the air after the post.

"That was exciting because I have had a bit to do with her and she has always promised to do that," Clipperton said. "She was just trucking coming to the turn and she just let go really well."

Leebaz was left in front at the 200-metre mark and had no answer to the winning burst from Gypsy Diamond.

"It was a funny run race, but he was very one-paced," Leebaz's jockey Tommy Berry said.

While Gypsy Diamond got runs through the field in the straight, favourite Malice had little luck, getting shuffled back through the field.

"It was one of those races where a thing didn't go his way," Malice's trainer John O'Shea said. "He raced a bit flat, being second-up, but he will keep going to the Hawkesbury Cup."
