Exciting juvenile Valour Road became the first Australian stakes winner for international sire Frost Giant with a brilliant debut win in the $250,000 Magic Millions WA 2YO Classic at Pinjarra on Saturday.

Frost Giant is an international Group One winning son of Giant's Causeway.

The MM Classic winner is the first named foal for the winning Street Sense mare Melba Avenue, a half-sister to multiple Hroup winner Raspberries. Valour Road's family also includes G1 winners Flavour and Sonntag.

Well fancied after showing great potential at the trials, Valour Road led from start to finish in the 2YO Classic under Aaron Mitchell.

"He'd shown us every sign that he could do it," Mitchell said. "I'm just so relieved we were able to get the job done."

Trainer Simon Miller went to $60,000 to buy Valour Road at last year's Magic Millions Perth Yearling Sale from the draft of Ron Sayers' Yarradale Stud.

Sayers retained a small share in the gelding and races him in partnership with a huge group of owners.

Epic Grey (Wicked Style x Embelish) broke through for a deserved first win at black type level when he scored a tough win in the Magic Millions WA 3YO Trophy (1200m).

The most consistent horse in Western Australia, and one of the most popular, Epic Grey overcame a wide run to score a solid win in a crack field.

Prepared by Lindsey Smith and with Daniel Staeck aboard, Epic Grey, like Valour Road, is owned by a large and excited group of owners.

Epic Grey was purchased for Smith by Craig Rounsefell of Boomer Bloodstock for $67,500 at the 2016 Magic Millions Gold Coast March Yearling Sale.

He is the second black type winner for Wicked Style, an American G1 winner by Macho Uno.

Epic Grey was bred by Neville Stewart of Oaklands Stud and farm client Alan Newcombe and sold through the Oaklands draft on the Gold Coast.

The grey is from the twice winner Embellish and her latest yearling, a Sidereus half brother to Epic Grey, will go under the hammer at March's Gold Coast Yearling Sale for Oaklands Stud.
