Chris Waller's dominance of Sydney racing has been recognised by bookmakers fielding on the $3 million Doncaster Mile.

As Waller trained another city treble at Warwick Farm on Wednesday, NSW TAB price assessors framed a market on the first of his six runners from his stable to finish in the famous mile at Randwick on Saturday.

Waller's Doncaster squad includes the second favourite Weary who will back up after winning the Doncaster Prelude at Rosehill last week.

"Form students are all over the in-form Weary who gets in with a light weight," the TAB's Glenn Munsie said.

Weary is $2.75 chance ahead of Hawkspur at $4 and Sacred Falls at $4.80 in Waller's race within a race.

The French import, a Tommy Berry ride, is $6.50 to give Waller four Doncaster wins with the Hawkes Racing-trained Messene the $4 favourite.

Saghann led home a Waller quinella in the TAB Early Quaddie Handicap at Warwick Farm before Abbasso broke through in the Hyland Race Colours Maiden Plate.

To complete Waller's treble, Beyond Thankful was backed from $4 to $3 before an easy win Pro-Ride Handicap.
