Gai Waterhouse has maintained her edge over Peter Snowden in the battle for the Sydney trainers' premiership with a winner at Warwick Farm.

But the honours on Tuesday were with young jockey Tim Clark who booted home a race-to-race treble.

Waterhouse had two runners at the meeting with Bermuda Bankroll winning the Hart Park Maiden Plate (1600m) to move her to 82-1/2 wins, 4-1/2 ahead of Snowden who didn't land a winner at the eight-race meeting.

Clark kicked off with a win on the Kris Lees-trained two-year-old Zingaling in the Randwick Betting Auditorium Handicap (1200m) and followed it up with a victory on stablemate Catacaos in the Stroud Park Handicap (1000m).

Clark completed the treble on the Anthony Cummings-trained Seeking Attention in the Shore Handicap (1000m).

"I came here knowing I had three good chances but to have them all winning was great," Clark said.

Hugh Bowman celebrated his 29th birthday by kicking further ahead in the jockeys' premiership with the win on Bermuda Bankroll and leads Corey Brown by 12 wins.

Brown, who returned from a one week Bali holiday, was stood down from riding after three races due to a stomach complaint and told stewards he vomited twice on the track.

The hoop told stewards he should be fit to ride at Canterbury on Wednesday.

The day was also a special one for Peter Wells who celebrated his first city win as a senior rider when he steered Sinful Warrior home in the Cherrybrook Handicap (1300m).

Wells who won the 2007-2008 Sydney apprentices' premiership, won a Group One on Newport in last year's Metropolitan Handicap and also outrode his claim with six months remaining on his apprenticeship.

The 24-year-old came out of his time on June 30.

"It's good to get that monkey off my back and show people what I can do," Wells said.

"I'll just keep working hard and doing the things I've been doing."

David Payne's domination of two-year-old racing in Sydney continued when huge colt Anchor Bolt by the late Anabaa scored in the opening race of the day the Georges River Maiden Plate (1600m).

Payne said the 2000 metre Group One Spring Champion Stakes in October was the main goal for the colt.

"He's going to be a very nice three-year-old but he's just a baby at the moment and doesn't know what he's doing," Payne said.

"He's a 2000 metre horse and we'll give him a go at the Spring Champion."
