Denmark's Caroline Wozniacki was the centre of attention when she took part in the Chickeeduck Tennis Clinic at Victoria Park earlier this month. Thirty children had the rare opportunity to meet the world number four who competed at the Hong Kong Tennis Classic 2010 which ended last Saturday. Wozniacki, 19, along with several former professional tennis players, conducted last Tuesday's clinic. The youngsters participated in a series of drills, including warm-ups, and practised their serves as their parents kept clicking the cameras. But the spotlight was on Wozniacki, whether she was serving or showing a child the correct way to hit the ball. Many children had brought tennis balls and caps for their idol to sign, and a few lucky ones were able to take a photo with her. Andrea Au, a student from Diocesan Girls' School, was particularly impressed with Wozniacki. 'Although I am not one of her fans, I think she is an amazing player. Her movement is so smooth and graceful,' she said. Tong Ka-po, a former professional player from Hong Kong and one of the coaches at the clinic, was very excited about the performance of the young participants. 'I am really happy to see young children who are so passionate about tennis. Looking at them play reminds me of myself practising tennis when I was a little girl,' Tong said. 'The kids at this clinic are really young but they have good fundamentals. If they practise hard and follow the coach's instructions, they have a great chance to become professionals.' Rika Hiraki, a former professional player from Japan who also instructed the children, said: 'This is a great activity for everybody to enjoy. All the children are well prepared and they played really well.' Towards the end of the clinic, Wozniacki teamed up with young local player Jeffery Chow for a demonstration game against Hiraki and Mikar Fisher, eight, a rising star from Britain.
