Nash Rawiller returned refreshed and invigorated from a short break in Hong Kong to leave Randwick with a perfect score from his four rides on Wednesday.

Last season's premier Sydney rider, Rawiller competed in an international jockeys' series at Happy Valley a week ago then stayed to enjoy the International race day at Sha Tin on Sunday.

He struck pay dirt immediately with his first ride aboard the Clarry Conners-trained Magical Anna then racked up wins with Teardrop Rock (Gai Waterhouse), Breeze Up (Bart Cummings) and Black Fix (John O'Shea).

"I think I rode four at Warwick Farm one day," Rawiller said.

"I know I've never ridden five in a day, but four from four is pretty special.

"It's been a good day."

Three of the first four winners on the day ran course records for the Kensington track including Breeze Up who was timed at 1:21.93 for the 1400 metres of the Bronte Maiden Plate.

He beat stablemate Wild Oats at what was his 11th start.

"This is where we thought we'd be a year ago," Cummings said.

"He's a Magic Millions horse so if he can win another race between now and then, he could get in to one of the races up there."

The Magic Millions race day is at the Gold Coast on January 15.

After Breeze Up's win, the track was upgraded from a good (3) to a (2), the first time anyone could remember such a rating.

"I don't think we've ever raced on a good two since the numerical system came in," Australian Jockey Club racing manager Col Tuck said.

The win of Black Fix in the Charing Cross Handicap (1400m) cemented the form from a benchmark 75 at Rosehill over the same distance on November 13 won by the Cummings-trained Shamash.

Black Fix became the eighth horse to finish behind Shamash in that race and subsequently win.

"The horse has done a good job," O'Shea said.

"He didn't get in as we had hoped but they didn't go as hard either so it worked out."

Brayroan was the first leg of a winning double for trainer Chris Waller and apprentice Nathan Berry with Sixtyfour bringing up the second leg.

Waller is a fan of Berry and his twin brother Tommy and believes they and Brenton Avdulla can make it to the top.

Avdulla and Tommy Berry are riding without claims while Nathan Berry still has a 1-1/2 kilo allowance.

"They are all extremely good riders who can go to the next level be in the top ten riders in Sydney in a few years," Waller said.

Waller retained a 5-1/2 win buffer over Waterhouse in the premiership, ending the day on 36 for the season so far.
