Sydney colt Your Song will have to overcome a wide draw if he is to add another Group One win to his record in the Doomben 10,000 on Saturday.

Your Song, a brilliant first-up winner of the Group One BTC Cup on a rain-affected track, has drawn the deepest barrier in a field of 15 for the weight-for-age sprint.

The three-year-old, who is set to be retired after next month's Stradbroke Handicap, still dominates 10,000 betting as a $2.50 favourite despite the alley.

Brisbane star Buffering, second favourite at $4.80, has also drawn off the course in gate 12.

Darley runner Epaulette has fared well in stall four and is a $6.50 chance with Rain Affair at $8 after drawing gate five.

Your Song will be reunited with jockey Hugh Bowman who takes over from the suspended Peter Robl at Doomben.
