BERLIN (AP) -- France's Amelie Mauresmo upset top-ranked Martina Hingis 3-6, 6-0, 6-4 Saturday to advance to the German Open final against Jennifer Capriati.

Mauresmo spoiled a showdown between Hingis and the fourth-ranked Capriati, who won when Belgium teen-ager Justine Henin sprained her ankle and retired in a dramatic end to a close match.

Capriati was leading 6-2, 4-6, 2-1, 30-40 when Henin slipped while lunging for a shot.

The injury spoiled the 18-year-old's chance to claim her second stunning upset after ousting second-ranked Venus Williams in the third round.

``I thought I could win this match, but it's still good for my game. Now I know I can beat anyone,'' said Henin, who will rise to 16th in the rankings.

Mauresmo, ranked ninth in the world, gained a measure of revenge against Hingis, who ended a 14-match winning streak by the Frenchwoman at Charleston, S.C., two weeks ago. Hingis fought back from 1-5 to 4-5 in the final set, but could only get one point on her serve in the 10th game and lost in 93 minutes.

``I thought I could come back whenever I wanted to,'' said Hingis. ``Maybe I'm saving myself for the French Open. That's the one that really counts.''

Hingis has gone five tournaments without a title after capturing three of the first five she entered this year.

She won the first set easily, then suddenly couldn't keep the ball in the court against the world's ninth-ranked player, whom she had beaten seven of nine times.

``There's not a lot of motivation left when you get two breaks and fall behind 0-4, but maybe it was a mistake, maybe I should have tried to tire her out,'' said Hingis. ``Maybe I wasn't hungry enough.''

Henin was close to tears and obviously in pain as her ankle was heavily taped during a 15-minute injury timeout. She played just one more point, which she lost, before withdrawing.

``I'm not happy about the way I won a match like that. Who knows what would have happened,'' said Capriati. ``But I'll just have to forget it and concentrate on the final.''

Capriati will be seeking her second straight tournament win. She has reached her fourth final in five events since winning the Australian Open in January.

Henin gave Capriati just as much trouble as she gave Williams, whom she ousted in straight sets as both players gambled on winners in what turned into an open slugfest.

Despite being only 5-foot-5, Henin showed a lot of power and slugged it out with Capriati for 1 hour, 37 minutes after the American dominated the first set.

``I didn't really want to let her get in the match, but then I suffered a lapse of concentration. That's something I still have to work on,'' Capriati said.

``She played very well the first set. There was nothing I could do,'' said Henin. ``But after that, I played very well. I was in so much pain I had to quit. I want to play the French Open,'' which begins in two weeks.

Capriati has now played four tough matches at the event, including a thrilling three-set win Friday against Conchita Martinez, last year's French Open finalist.

The American said she is very happy with her game, playing her first tournament on European clay this year.

``It's getting better and better. One way or another, I'm very happy with my game,'' the third-seeded Capriati said.

Capriati trailed 1-3, 0-40 in the second set, then suddenly rattled off 10 straight points and appeared close to taking a two-set victory. But she couldn't keep hitting shots at that high level, and afterward almost every game was fiercely contested with several deuces.

Henin will rise to No. 16 in the rankings, continuing her climb after breaking into the top 50 last year.
