MICHAEL Chang has confirmed his participation in April's Salem Hong Kong Open at Victoria Park. Defending champion Chang will be the star attraction at the April 15-23 event along with his compatriot, Australian Open and US Open champion Andre Agassi - currently the world's hottest player. 'I'm really looking forward to my return in April and the defence of my first ever Hong Kong Open,' said Chang. 'A final between Michael and I would be quite a showdown,' said Agassi. 'We are both playing well but I will definitely be looking to win the tournament, although I am sure Michael and all of the other players in the draw will do all they can to keep me from winning the title.'
