MIAMI (Reuters) — Belgian Kim Clijsters brought a swift end to Venus Williams's 15-match winning streak with a 6-2 6-1 win in the Sony Ericsson Open final on Saturday.

The 14th seed needed only 58 minutes to defeat the third-seeded American, who played with bandaging on both legs and  said afterwards she may have trained too hard during the tournament.

The match was reminiscent of last year's final at Key Biscayne when Williams's sister Serena, also looking short of fitness, surrendered in similar fashion to Belarussian Victoria Azarenka.

Williams said she had worn the bandaging on her legs as she felt her knees, a frequent source of trouble, needed extra support.

She also may have overdone her practice routine during the tournament.

''I think sometimes you have to be careful with practice, not to practice too long. I may have made a mistake with that a little bit. I know better, but 'Eager V' kind of burst through,'' she said.

''Overall I'm really happy with the tournament. Unfortunately, today I didn't win the match, although I felt like this is a match I could win. Unfortunately I made it a little bit too easy. Next time around I'll play better.''

Clijsters returned to tennis last year from a two-year break to give birth to daughter Jada, who watched from the stands.
