Stumbling Seles suffers Hingis Miami wipe-out.
Seles, who refused to blame a twisted ankle, had never failed to win a game in 534 career matches. 'How do you feel after that?' she asked. 'It's a semi-final and I expect a lot more.'
Seles, who has now lost ten of 12 matches against Hingis, appeared slowed by her ankle problem and did not cover the court well. 'I heard two days ago that her foot was starting to bother her,' Hingis said. 'I don't think anyone else would have finished the match.'
The last time Hingis won 6-0, 6-0 was against South African Joanette Kruger in the third round of this tournament in 1998.
In the mens' quarter-finals, second seed Pete Sampras beat No 9 seed Nicolas Lapentti 6-3 7-6 (7-3).
