The Gai Waterhouse and Adrian Bott stable delivered the Breednet ‘One to Watch’ on Thursday with a resounding debut victory at Hawkesbury for a son of the former Waterhouse trained Golden Slipper winner Sebring. Three year-old colt Penske was a short priced favourite for the 1000 metre maiden and after jumping brilliantly from gate one set up a commanding early lead. Held together in the lead by Brenton Avdulla, Penske turned for home more than three lengths in front and maintained his margin to win in a brisk 56.62 seconds. Penske was a $150,000 Inglis Easter purchase for Gai Waterhouse/Julian Blaxland from the Yarraman Park draft and was bred by David Bentata. He is the first winner for Princess Natural, a half-sister by Danehill Dancer (IRE) to stakes-winner Zizou from the family of leading sire Not a Single Doubt.
