It promises to be a meeting of significance for Chris Waller and Sydney racing on Saturday but the trainer insists there will be nothing different about his planning for Rosehill.

Nevertheless, Waller appears to have a lot of angles covered as he tries to break a long-standing Sydney trainers' record.

With 11 runners across seven races, Waller will be at unbackable odds to overtake Tommy Smith and Gai Waterhouse for the most city winners in a season.

Six of those horses are favourite in early betting with Secessio the shortest priced at $3.40 to win the TAB Rewards Handicap (2400m).

Waller will also saddle up the Civic Stakes favourite in Said Com ($4.20) with his hand in the Listed race strengthened by the inclusion of Nocturnelle and Disciple.

Smith, easily the most dominant trainer of his era, led in 156 winners in 1975-76, a mark equalled by his daughter in 2002-03.

Waller goes into his home-track meeting with 155-1/2 winners but he has learnt not to get ahead of himself when it comes to records following a mini run of outs before a winning double at Warwick Farm on Wednesday .

"When you are coming up to a mark it just seems to take an eternity," Waller said.

"All I can do is just make sure I've got chances in races."

Not surprisingly, Waller's Rosehill statistics are clearly his best with 51 winners from 270 starters so far this season returning a 19 per cent winning strike rate and more than $4.3 million in stakes.

He trained a career-best five winners at a Rosehill meeting in May, acknowledging the value of a "home track" advantage.

"I think it is worth a half length to our horses," he said.

If early betting is a guide, Waller could be celebrating as early as the second race on Saturday with Oompa Loompa into $3.80 in the Become An ATC Sponsor Handicap (1200m).

The three-year-old chased home stablemate Relaxed And Happy last start after winning over Saturday's course three runs ago.

On the back of a favourable weather forecast, Rosehill track manager Chris Toogood says racing will be run on a drying surface.

"With a few more days of good weather, there's a chance of an upgrade into the slow category," he said.
