Federer sets up clash with Roddick

Roger Federer held off local wildcard Ryan Harrison to set up a third-round clash against twice former Sony Ericsson Open champion Andy Roddick and Serena Williams served her way into the fourth round in Miami on Saturday. 

While men's number one Novak Djokovic and women's second-ranked Maria Sharapova progressed easily, former number one and twice Miami winner Kim Clijsters was eliminated at the Premier-level event. 

Clijsters fought hard and survived six match points before falling to fellow Belgian Yanina Wickmayer 6-4, 7-6 in their third round clash.

Australia's US Open champion Samantha Stosur avoided an early exit by storming back after falling a set and 4-2 down to beat South African Chanelle Scheepers 2-6, 7-5, 6-2.
Federer, who has won 40 of 42 matches and six tournament titles since the 2011 US Open semifinals, led his 19-year-old opponent 5-2 in the second set before Harrison extended him to a tiebreaker taken 7-3 by the Swiss for a hard-earned 6-2, 7-6 win.
 
Roddick lost only nine points on serve and thundered down 10 aces to beat Luxembourg's Gilles Muller 6-3, 6-2. Djokovic prevailed over Marcos Baghdatis 6-4 6-4, subduing the Cypriot without the loss of a set for the first time in their last six meetings.
American Williams, the 10th seed, belted eight aces in an overpowering 6-2. 6-1 rout of 21st seed Roberta Vinci of Italy. "I played okay" said Williams. "I can definitely do better but I haven't played a lot,’’ she added.

Williams, whose five Miami triumphs tie her with Steffi Graf for the record, said she was still hungry for more. "I need trophies," she said.

Second seed Sharapova advanced to the fourth round with a 6-4, 6-2 win over American qualifier Sloane Stephens, while fourth-seeded Caroline Wozniacki beat Czech Petra Cetkovska 6-3, 7-5.

Also coming through on Saturday was eighth-seeded Li Na of China, who won the last four games of each set to beat another Czech, Iveta Benesova, 7-5, 6-2.
