Kim Clijsters ensured that her last match on Belgian soil will be a tough encounter when she set up a Diamond Games final against Amelie Mauresmo.
Clijsters faces an emotional final match in Belgium on Sunday
French top seed Amelie Mauresmo battled to a 6-3 3-6 6-2 win over Russia's Anna Chakvetadze in the first of Saturday's semi-finals in Antwerp.
And Clijsters, 23, then gave her home crowd what they wanted by defeating France's Tatiana Golovin 6-4 6-3.
Clijsters is playing her final Belgian event before retiring later in 2007.
"Tomorrow will be a very emotional day and I am just glad that I am still here to enjoy it and am in the final," said Clijsters.
World number three Mauresmo is looking to find some form after a slow start to the year.
She broke Chakvetadze's serve in game seven on her way to securing the first set but the 19-year-old Russian fought back to take the second set after an early break.
Mauresmo then moved up a gear in the decider to claim her second win over Chakvetadze in a week, following their quarter-final in Paris last week.
But there were worrying signs for the Wimbledon champion, who seemed to be carrying a leg injury in the final set.
"I didn't return well, I had too many ups and downs," said Mauresmo. "I was really going forward to take control of the match."
She had an extra incentive to reach the final, however, as she can claim a diamond-studded racquet awarded for three title wins in five years having also won in 2005 and 2006.
The racquet is made of five kilos of gold, with 1,900 diamonds totalling 240 carats.
"I would be lying if I said it was not a dream prize," said Mauresmo. "Every match I win, it is starting to be a little bit more on my mind, but the final will be the toughest one to win."
Clijsters said: "It will be a very special match.
"Amelie is playing for the fabulous racquet and, as far as I'm concerned, I just want to thank all of my fans by giving them one last success in Belgium."
