Promising gelding Shiraz is favourite to upset dual Group 1 winner Trust In A Gust on Saturday.

Online bookmaker sportsbet.com.au has opened Shiraz as the $2.40 favourite for the Aurie’s Star Handicap.

Trust In A Gust, who will lump 60 kilograms as topweight, is $3.30 for the Flemington Group 3.

Lonrockstar ($9.00) is the only other runner under double figures.

Zebrinz, who won three in a row before a spell, is $15.

“There’s no doubting Trust In A Gust is the best horse in the race, but the big weight is against him. Shiraz is chasing three wins in a row and has race fitness on his side,’’ said sportsbet.com.au’s Christian Jantzen.
