MADRID, Spain -- Justine Henin-Hardenne will finish the year as the top-ranked player in women's tennis after beating Maria Sharapova 6-2, 7-5 (5) on Saturday in the semifinals of the WTA Championships.
Henin-Hardenne will face defending champion Amelie Mauresmo in Sunday's final, with $1 million going to the winner. Mauresmo advanced to the final with a 6-2, 3-6, 6-3 victory over two-time winner Kim Clijsters.
The victory clinched Henin-Hardenne's second year-end No. 1 ranking. Mauresmo will finish her 34 consecutive weeks as No. 1 at the end of the tournament.
Henin-Hardenne won the French Open and was the runner-up at the three other Grand Slam tournaments this year -- the first woman since Martina Hingis in 1997 to reach all four major finals. She lost to Mauresmo at the Australian Open and Wimbledon.
Mauresmo also defeated Henin-Hardenne in a round-robin match Friday.
"It's the last match of the year and obviously it's great to have Justine and I in a final again, after we had a tough match yesterday," Mauresmo said. "Hopefully she'll party [tonight] with her No. 1 ranking."
Henin-Hardenne can clinch a tour-high sixth title of 2006 in Madrid after missing nearly two months while recovering from a muscle tear in her right knee.
"It's amazing. I'm very happy," Henin-Hardenne said. "I'm very happy with the way I handled the pressure today. The season is not over yet. I'm No. 1 but I still want to win this tournament.
"I had a great season and I know there are a few players who deserve it, too, but it's not easy to go to the four finals of the Grand Slams, and I played very consistently all year. So I think I deserve [No. 1]."
Henin-Hardenne beat Sharapova for the third time in four meetings this year -- the Belgian's only loss coming in the U.S. Open final.
Henin-Hardenne, who had seven aces, had three service breaks in the first set while forcing Sharapova into 14 unforced errors. Henin-Hardenne converted her fourth break point in the eighth game of the second set to take a 5-3 lead when Sharapova hit a forehand into the net.
Sharapova rallied with her first break of the second set when Henin-Hardenne sent a forehand into the net. Both players then held serve to force the tiebreaker.
The Russian saved one match point at 6-4 in the tiebreaker, but Henin-Hardenne converted on her second try to give Sharapova only her second loss in 11 tiebreakers this year.
"I just didn't feel like myself today," Sharapova said. "I felt a little sluggish. I didn't feel like I was concentrating.
"You hope to find a way to break through that, and I felt like I was getting there at the end of the match, but I just couldn't put two or three good points together."
Sharapova finished the season with a career-high five titles, including her second Grand Slam title at the U.S. Open.
"I've had an amazing year, a very successful year, and I'll finish the highest I have in my career," Sharapova said. "You always think about what went wrong and what could have gone better, but I'm happy with the way I played and just look forward to what I can improve for next year."
