Stanford: Second-seeded Maria Sharapova set up a possible quarter-final match with Serena Williams by beating Slovakia's Daniela Hantuchova 6-2, 2-6, 6-4 on Wednesday at the Bank of the West Classic.
The fifth-ranked Sharapova, who reached the Wimbledon final, questioned an out call that would have ended the match. She regrouped and won the next two points to set up the possible match between two former world No. 1s.
"It's still about improving the little things to get more consistent," Sharapova said. "I've had to make a lot of tough choices in the last year but I'm going in the right direction and, little by little, those choices are paying off."
