Two of Sydney's biggest training operations have carved up Wednesday's Canterbury meeting, winning six of the seven races between them.

Peter Snowden and Chris Waller each trained a treble with Allan Denham the only other trainer to get on the board when he produced First Class Ticket to win the final race.

Darley's head trainer Snowden won the opening two races with Iriomote and Moderate before Adage made it a triple treat with an overdue victory in the TAB.com.au Handicap (1100m).

In what is set to be a handy form race, Adage beat some superbly bred rivals including Most Joyful, a sister to multiple Group One winner More Joyous and Polarmore who is a son of Golden Slipper winner Polar Success.

Snowden is hoping Adage can build on his winning momentum.

"It looked a good race on paper and hopefully it will turn out to be a good form race," Snowden said.

Flamboyant businessman John Singleton arrived at Canterbury by helicopter to watch Most Joyful run.

The filly started the $4 favourite but never threatened to finish eighth.

A disappointed Singleton said he would now turn his attention to his two feature race runners on Saturday, Dear Demi in the Turnbull Stakes at Flemington and Ironstein in the Metropolitan at Randwick.

"Before today she was very exciting, now the two on Saturday look more exciting," Singleton said.

The race almost brought Nash Rawiller's spring plans undone when he narrowly avoided a careless riding suspension for shifting in twice aboard Most Joyful near the 600m and again near the 800m.

In the end, presiding steward Marc Van Gestel stopped short of giving the top jockey time on the sidelines.

"By the barest possible margin we issue a reprimand but it doesn't get much closer than that," Van Gestel said.

Waller's three winners came in consecutive races.

Progressive mare Wind Bender backed up from her Canterbury victory last Wednesday to make it two in a row before Triple Fortune and You'll Never added to the premier trainer's tally.

Wind Bender, who finished sixth in the Australian Oaks during the autumn, could be given another opportunity in stakes grade.

"We could look at the Tatt's Cup. It's going to be another step again and she's going to have to do everything right," Waller said.
