Serena crushes Sharapova
American number one Serena Williams easily disposed of top seed Maria Sharapova 6-1 6-1 to reach the Miami Masters quarter-finals in an imperial repeat performance of the pair's Australian Open final result.
Williams, playing her first event since beating Sharapova in January to lift her eighth grand slam title, brushed past the world number two in 58 minutes.
The target of racial abuse by a heckler on Monday, the American heard only cheers as she finished off her opponent with a forehand winner.
Williams's victory also avenged her sister Venus's defeat by Sharapova in the third round.
The 13th seed, three times a winner of this trophy, next meets eighth-seeded Czech Nicole Vaidisova.
"I know her game pretty well. We've played each other a few times and I like her style," said Williams.
Sharapova acknowledged that she had been demolished in the match.
"Once she gets up in the set or the match she seems to steamroll," the 20-year-old Russian said.
"I'm definitely going to be out on the practice court and working hard."
"I'm not going to look at it as a confidence thing. I have to look at what I'm doing and how I'm going to improve it so it gets better."
Russian Anna Chakvetadze also reached the semi-finals in Miami coming back from a set down to beat China's Na Li 4-6 7-5 6-2.
Chakvetadze will now face second seed Justine Henin in the semi-finals after the Belgian overcame Nadia Petrova 7-6 7-6.
