At Indian Wells, Calif., it was all in the ankle for fourth-seeded Manuela Maleeva, who rebounded from being down 4-1 in the first set to beat Jenny Byrne 6-4, 6-1 to win the $250,000 Virginia Slims tennis tournament.

Maleeva, who suffered a sprained left ankle Friday in the quarterfinals against Catarina Lindqvist, swept six straight games to take the first set and the final six games of the second set to defeat Byrne in 70 minutes Sunday.

"It (the injury) made me better mentally," said Maleeva, 22, of Bulgaria, who won $50,000. "I had to get stronger. I realized when I was down 4-1 in the first I really wanted to win."
