Chris Waller will reignite his quest for a slice of Sydney racing history at a bumper meeting at his home track on Saturday.

The premier trainer will have up to 18 runners across the nine Rosehill races, four of them early favourites.

Waller sits on 153-1/2 wins for 2012-13 and if he can add just three more he will establish a new benchmark for training Sydney winners in a season.

His record-breaking mission has been stymied by rain which washed out the final five races at Randwick last Saturday along with Tuesday's Warwick Farm program.

But Waller is anything but agitated by the interruption to his flow of winners.

"You just have to take what you're given," he said.

"In racing, you don't make things happen you have to wait for them to happen."

Waller's achievements this season are put into perspective by the gap to his nearest premiership chaser Gai Waterhouse.

He has trained more than double Waterhouse's 75 city winners this term.

Added to that, he is the nation's leading Group One trainer with Red Tracer's Tattersall's Tiara victory last weekend taking his season tally to nine.

Waller's leading hopes at Rosehill include last-start winner Relaxed And Happy, the $2.30 favourite for the TAB iPhone App Handicap and Eigelstein who is top fancy at $4 for the Rygate Surveyors Handicap (1200m).
