After winning five races on the card at Doomben a fortnight ago, Blake Shinn is not getting too carried away about his chances of adding another group 1 when he returns to the track on Saturday.

Shinn rides three of his five winners from a fortnight ago, when he won the Doomben Cup on Pornichet and BTC Cup on Hot Snitzel. Another of his winners Charlie Boy steps up to group 1 level in the Doomben 10,000.

“I started the carnival up there very well and I want to keep it going, but things are a bit different for Charlie Boy this week,” Shinn said. “Last time he had the good draw and right weight in the right race and got the job done. This time he is at weight-for-age, got an outside barrier, so there is as much against him as there was for him last time. We don’t know how much confidence he took from that win because it had been a while since he had won and that could be a factor as well.

“He is a very talented horse but against the quality he is up against he will need a bit of luck. I don’t think he is out of place at group 1 level but it is a tough ask.”

Charlie Boy is on his way to the Stradbroke in a fortnight’s time, where he will be better suited under handicap conditions. Shinn won’t ride him in the Stradbroke as he is already committed to another from the Peter and Paul Snowden stable in Hot Snitzel. “It is more the weight than anything else that made the choice for me,” Shinn said.

He will continued the build up towards the Queensland Oaks and Derby with Gai Waterhouse’s Bohemian Lily and Chris Waller-trained Sadler’s Lake respectively on Saturday, which means he has rides for the three biggest public yards in Sydney.

“When you are going to the races and riding for those stables, you are confident. It is something I have worked hard to get and I understand there is a responsibility and expectation,” Shinn said. “Sadler’s Lake is also drawn poorly [in the Grand Prix] but he won well last time. It might be a bit more difficult this time for him from the draw. I went to the front last time but he has the talent to be ridden back and win. I have a lot of time for Bohemian Lily and she keeps improving. She is going to peak next week for the Oaks.

“They are are both on track for the Oaks and the Derby. I haven’t won an Oaks or Derby before and it is something I would really like to do and these are good chances.”

Shinn’s best ride might be his last on Saturday as he rides Rekindled Interest in the Fred Best Classic. “He is one I didn’t win on at the last meeting but his run was great. He is a serious horse going towards the Queensland Guineas. He is drawn poorly also, it is my lot for the day, but if he gets a fair crack at them look out,” Shinn said.

Shinn continued to rack up the winners in Sydney booting home Istanbul for Danny Williams at Randwick on Wednesday, but a winning double to premiership leader James McDonald means he is eight wins back. “It is still something I would like to win [the Sydney premiership] but for the next couple of weeks Brisbane is the focus,” he said.
