Adelaide: Australian left-hander Chris Guccione will play top-seeded Novak Djokovic in the Adelaide International final after each won their semifinals on Saturday.Guccione beat Argentina's Juan Martin Del Potro 5-7, 6-3, 7-5 at Memorial Drive. It was the South American's second match of the day _ Del Potro beat Igor Kunitsyn of Russia 6-2, 6-0 earlier Saturday in a quarterfinal postponed from Friday by rain. Djokovic also took advantage of another player who had his quarterfinal and semifinal Saturday, beating Joachim Johanssen of Sweden 6-3, 6-2.Johanssen beat Vincent Spadea of the United States 7-6 (7), 6-3 in a quarterfinal on Saturday morning.As he had done in his upset of second-seeded Richard Gasquet on Friday, the hard-serving Guccione dropped the first set but grew in strength as the match progressed. He had 19 aces."(I) wasn't expecting it before the tournament started, I was happy to get into the quarters, happy to make the semis, and now one more match and I'm holding up the trophy," said Guccione. "I couldn't be happier at the moment."I've already had a lot of text messages just in the last five minutes, and my mum and dad and brother are up here so they're all pretty happy at the moment."Asked if his breakthrough week could be seen as a sign that there was more to the men's game in Australia than Lleyton Hewitt and Mark Philippoussis, Guccione nodded."I hope so, I'm ranked 150, so to get top 100 is the immediate goal, and once I do that I think we're a good chance, we've got a few young guys coming through as well," he said.
