Yarraman Park’s top class young sire Hinchinbrook featured at Ascot in Perth on Saturday when his brilliant daughter Whispering Brook kept her winning streak intact going five for five when taking out the Group III WATC Sires Produce Stakes. The Simon Miller trained filly had won her four previous starts, the last of them a bold front running victory in the Group II WATC Karrakatta Plate at the start of the month over 1200 metres. Ridden more quietly this time by Peter Knuckey when stepped up to 1400 metres for the first time, Whispering Brook found the line well to score by half a length. A $45,000 Magic Millions National Weanling purchase from the Hillside Thoroughbreds draft for Aquanita Racing, Whispering Brook has won all five starts to date earning $635,350 in prizemoney. Bred by Hillside Thoroughbreds, Whispering Brook is the second winner for Artful Whisper (USA), a half-sister to stakes-winner High Maintenance. Artful Whisper has a yearling colt by Medaglia D’Oro (USA) that was sold as a weanling for $100,000 at the Inglis Great Southern Weanling Sale and then made $120,000 at Karaka and was covered last year by in form sire Written Tycoon. Whispering Brook is one of four stakes-winners for Hinchinbrook, who is a dominant leader of the Australian Second Season Sires division with some $3.3 million in progeny earnings this season. Among those winners is Bjorn Baker’s promising three year-old Brooklyn Storm, who opened his Brisbane campaign with a resounding five length win at Toowoomba on Saturday. A modest $22,000 Inglis Scone Yearling Sale purchase from the Yarraman Park draft, Brooklyn Storm has three wins and four placings from nine starts with prizemoney topping $80,000 and looks to have many more wins in store. A three-quarter brother by Fastnet Rock to Snitzel, Hinchinbrook has had a service fee increase for 2016 and will stand at $38,500.
