Youngsters from the Peter and Paul Snowden stable have won three of the nine official barrier trials for two-year-olds at Randwick.

Godolphin juveniles won two heats while Chris Waller, Kris Lees, Richard and Michael Freedman, Gai Waterhouse and Adrian Bott and Mark Newnham were the other trainers to post winners on Monday.

Godolphin's Beyliks was an impressive winner of the first of the 852m-heats while stablemate in Flanders won her trial over 847m.

The Snowden winners were Nitrous, Barbaric and War Memorial.

Horses that compete in the officials trials get first preference for entry into the early two-year-old races.

The first juvenile features, the Breeders' Plate and the Gimcrack Stakes, are on October 5 at Randwick.

The $3.5 million Golden Slipper in March at Rosehill is the world's richest race for two-year-olds.
