The Boxing Day meeting at Caulfield was one to remember for fledgling trainer Mitchell Beer and also apprentice Harry Coffey.

And this time at Caulfield the two will team up with Coffey booked to ride three-year-old filly Jacqui's Joy on Saturday.

Jacqui's Joy gave 27-year-old Beer, who trains in partnership with Max Hinton at Mornington, his first city win when Patrick Moloney rode the filly to victory over 1400m.

Later that day Coffey landed his first stakes wins with a feature race double aboard the Darren Weir-trained Tuscan Sling and Signoff.

With Moloney serving a careless riding suspension, Coffey has been called on to ride Jacqui's Joy in Saturday's 1400m-benchmark 70 for fillies.

"Given the luck they both had last Saturday week, I think they'll make the perfect combination at Caulfield," Beer said.

Jacqui's Joy has won a maiden at Kilmore and a fillies' benchmark 70 in town in her two Australian starts after being bought from New Zealand where she raced four times.

"She spelled in New Zealand and also spelled when she arrived here in Australia and from the moment she has come into work she hasn't put a foot wrong and we haven't had an issue with her," Beer said.

"She's just thrived since arriving in Australia."

Beer has had his trainer's licence for just over a month and said getting a city winner so soon was unreal and a day he will never forget.

"And I can't wait to get my next one," he said.

He hopes that can be on Saturday and said they couldn't be happier with Jacqui's Joy since her Caulfield win.

"It looks like the same sort of bunch of horses on nominations and I think her run the other day at Caulfield to get home over the top of them off a slow tempo certainly makes us believe that her being a Saturday winner hopefully wasn't a one-off," Beer said.

Beer said they would have liked to step her up to 1600m but without a suitable option decided on Saturday's 1400m race.

He said the plan was to then to give the filly a short break and hopefully target the Brisbane winter carnival and the Queensland Oaks.

"It's a long, long way away but winning a Saturday race at Caulfield was a long, long way away from a heavy 10 maiden in New Zealand," he said.

"We'll head towards that and see if we can get there."
