Geary snared the first Group 1 win of his driving career as he steered My Sweetchilliphilly to a commanding victory in the Gold Tiara Final (1,730 metres).

Over the course of the final lap at the Bathurst Paceway, Geary took it to favourite Lady Chatto before his chance kicked clear with around 300m to go.

My Sweetchilliphilly then flew home to win by a massive 20¾m in a Bathurst two-year-old fillies class record 1:54.7 mile rate, bettering her own mark of 1:55.2.

The class record also meant she was the fastest winner in the 31-year history of the Gold Tiara, an honour which previously belonged to 2016 victor Dont Think Twice (1:56.2).

Shane Tritton, who trains the Betterthancheddar x Tact Philly filly with his wife Lauren at Menangle, praised the effort of Geary.

“Chris mate, you’ve earned that. You had the balls to drive her like that and you came out with the chocolates, so well done,” he said.

While Geary admitted his aggressive tactics paid off, he gave plenty of credit to My Sweetchilliphilly as well.

Saturday’s win was her third in a row with Geary in the gig, adding to a 59.7m victory on debut and burning her rivals by 22.3m in her Gold Tiara heat.

“There were probably one or two things that was going to happen. We could’ve sat back or went around and sat quite and let the leader get away and run their race, or we could’ve drove her the way we drove her and the best filly wins at the end of the day,” Geary said.

“I am really pleased that it worked out that way and I am just really grateful that I get the opportunity to drive these sorts of horses.

“We were both probably all out on our feet at the top of the straight and this filly is is something special, she digs deep.

“She has only had the three starts, but she tries every time she goes out there and I’m sure she’ll only improve and get better with age.”

The final was expected to be a battle in two between My Sweetchilliphilly ($2.70) and the Tim Butt, New Zealand trained raider Lady Chatto ($1.80 favourite).

Until Geary’s chance skipped away down the home straight, that was how it played out.

Lady Chatto, who was attempting to become the first Kiwi to win the two-year-old fillies feature, began well from barrier six and crossed to lead.

She clocked a 56.9 seconds first half then a 27.8 third split before My Sweetchilliphilly ran away from her down the home straight.

Lady Chatto had to settle for second, holding off Bathurst trainer Amanda Turnbull’s Now Eye See ($15) by a half head.
