A jockey who rarely rides in the city has been given the credit for Better Not Blue making a winning metropolitan debut at Warwick Farm.

Michelle Ritchie trained her first city winner when the three-year-old claimed the TAB Place Multi Handicap on Wednesday but she said it could not have happened without Brewer.

"I probably wouldn't have run him in town if Robbie hadn't been able to ride him," the Kembla Grange-based Ritchie said.

"Robbie knows the horse, he trials him for me and he rides him in jump-outs. He's stuck by me and I really wanted to reward him."

Sent out favourite at $2.50, Better Not Blue settled beyond midfield against his five rivals but in a replica of an authoritative Moruya win last month, he put himself into the race with a minimum of effort.

And the result was never in doubt from the 200m as Better Not Blue skipped through the rain-affected track to win by 2-1/2 lengths.

"He gets back in his races because he doesn't get out of the gates too quickly but as soon as he straightens up and finds a bit of daylight he goes bang," Ritchie said.

Before winning at Moruya, Better Not Blue ran second to Cap Domingo, a horse which has attracted the attention of bloodstock agents acting on behalf of Asian clients.

Much to Ritchie's surprise, there has been no such interest in Better Not Blue, a $10,000 ready-to-run sale purchase.

"Funnily enough I've had not one person even inquire about him," she said.
