Matamata trainers Lance O'Sullivan and Andrew Scott will thrust in-form mare Sleeping Beauty into the deep end at Pukekohe on Saturday when she contests the Gr.2 Dunstan Feeds Auckland Thoroughbred Breeders' Stakes (1400m).

Talented mare Sleeping Beauty proved too slick for her rivals when she led all the way to take out the day’s open sprint contest over 1300m at Tauranga.

Lightly raced speedster Sleeping Beauty was back to her brilliant best when she dominated her rivals from in front over 1200m at Matamata on Saturday.
