Boss has not been on Kermadec since his famous Doncaster victory in April and is looking forward to seeing him before hopping on him in the Warwick Stakes at Randwick on Saturday.

"I didn't come up and ride him because he was only having a couple of quiet trials and he had that gallop last week," Boss said. "The thing with the jump from three-year-old to four-year-old seasons is how much they improve and mature.

"I can't wait to see him in the flesh because I think he could be something special. There is a hole at the top of weight-for-age ranks and I really think he could be the horse to fill it.

"Having said that it is one thing winning a Doncaster with 51kg getting the right run and another becoming a weight-for-age horse but he gives me the feeling that he can do it. But we will just have to wait and see."

Kermadec is being aimed at the Cox Plate but will take the Sydney weight-for-age path where he could become a pin-up horse.

Boss pointed out that given a bit of luck at the end of his autumn campaign Kermadec could have been in the running for the horse-of-the-year title. His fourth in the Australian Guineas came as he was held up for a long period in the straight before charging late to go down by 1 lengths. He then came from last to run third at his first crack at weight-for-age in the George Ryder Stakes, two lengths from Japanese miler Real Impact and Criterion, who would go on to win the Queen Elizabeth Stakes.

"When you look back it was the run that said he was the one to beat in the Doncaster," Boss said. "If things had gone his way he could have won all three of those [group 1] races and he would be an established star. He had a real sprint at the end of the Doncaster, that is something that the good ones have but he still has to prove it in a way. I'm sure if he has developed he can prove a star in the spring."

Chris Waller glowed about Kermadec after his gallop at Rosehill last Saturday and has set him to continue to get the job done from the beginning of his preparation.

He will saddle six runners in the Warwick Stakes but stayers Beaten Up, Foreteller, Moriarty and Hawkspur are starting campaigns which will be aimed at longer races, leaving Kermadec and Royal Descent as his two main chances.

"With a horse like Kermadec that is a group 1 winner, you want to get them going early on and get the job done with them again to take the pressure off," Waller said.

"He has turned the corner in the past couple of weeks and him and Royal Descent are our main chances. She has come up lot stronger this time than she was in the autumn."

Kermadec has been quoted at a generous $7 to win the Warwick Stakes by Ladbrokes, which have First Seal a $2.90 favourite after a couple of impressive barrier trials.

Royal Descent is $6.50 second favourite, while chances are given to Godolphin's It's Somewhat at $7.50 and Pornichet and Burbero, which share the $9 line.
