Sussex has produced two British junior champions in Rachel Willmott and Chris Simpson.

The pair were crowned at the City of Manchester courts which staged last year's Commonwealth Games.

Wilmott claimed a record SIXTH national success in the girls' under-17s and Simpson took the boys' title just a month after moving from the Channel Islands to Brighton.

Michael Harris, who coaches them both, said: "It's wonderful. I set incredibly high standards and through a lot of hard work and talent Rachel and Chris reached them."

Farlington pupil Willmott, 15, made it six of the best despite a stomach bug when she defended her title by destroying Leone Holt (Warwickshire) 3-0 in a 20-minute final, dropping just five points.

She answered question marks over her fitness with whitewash victories against Yorkshire pair Dion Saffrey and Sapphire Sutcliffe in the last eight and semi-finals respectively.

But her display in the final underlined her superiority.

Harris also revealed how he used kidology to help her to victory.

He said: "Rachel is so dominant that her opponents throw everything at her including the kitchen sink and, although she can deal with the business end of the tournament and could have been blase as it was her sixth final, the level of expectation made her nervous.

"So I told her I didn't think she did as much as she could have done in the semis. I did it on purpose. I wanted to wind her up.

"I also reminded her of what she'd achieved and to go for it. It was a totally one-sided final."

Harris believes his protege has the potential to "change the face of squash like the Williams sisters have done in tennis due to her athleticism".

The Horsham club ace also completed national doubles at under-13s and under-15s.

Simpson, 16, a pupil at Brighton College, destroyed Chris Hall (Warwickshire) 3-0 in the final after dismissing Welsh No.1 Peter Creed with the loss of just two points in the last four.

Harris, who coaches Simpson at Coral's (Hove), said: "Chris played well. It's great to have a quick reward for our working relationships.

"Chris felt isolated living on Guernsey. He needed help and wanted to move to the mainland.

"Chris chose Sussex for two reasons. He was impressed with Dr Anthony Seldon, the head at Brighton College, who sold the school and what it could do for him. Secondly, Chris knew me from national squad sessions I have taken with him."

Simpson thanked Harris for inspiring a successful defence.

He said: "Michael has already improved me by working on my movement and speed. I've also settled quickly in Brighton and at the school. I'd had injury and illness so I was extra happy to have won. I played quite well."
