Berlin The German Open was supposed to be a showdown between Martina Hingis, Venus Williams and Jennifer Capriati.
No one told France's Amelie Mauresmo or Belgium's Justine Henin.
Mauresmo took care of the top-ranked Hingis 3-6, 6-0, 6-4 in Saturday's semifinals, while Henin came close to ousting the other two stars single-handedly.
Henin, who had already upended Williams, sprained her ankle against Capriati and retired in a dramatic end to a close match against the No. 4-ranked American.
Capriati was in front 6-2, 4-6, 2-1 with the 18-year-old leading 40-30 in the fourth game when she slipped while lunging for a deep shot at the $1.185 million event.
"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.
Henin was close to tears and obviously in pain as her ankle was heavily taped during a 15-minute delay. She played just one more point before withdrawing.
Mauresmo, ranked ninth, gained revenge for Hingis ending her 14-match winning streak at Charleston, S.C., two weeks ago. The Swiss player fought back from 1-4 to 4-5 in the final set, but then could win only one point on her serve and lost in 93 minutes.
Hingis has gone five tournaments without a title after capturing three of the first five tournaments she entered this year.
Capriati will be chasing her second straight title as she reached her fourth final in five events since winning the Australian Open.
