Updated: March 25, 2012

Roger Federer set up a third-round clash against twice former Miami Masters champion Andy Roddick, when he defeated Ryan Harrison in straight sets.

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.

Federer next takes on Roddick who has beaten 21 out of 23 occasions. Roddick lost only nine points on serve and thundered down 10 aces to beat Luxembourg’s Gilles Muller 6-3 6-2.

Novak Djokovic, meanwhile, 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.

Men’s fifth seed David Ferrer, another hot player on the men’s tour with three titles this year, converted four of 10 break point opportunities to beat 19-year-old Australian Bernard Tomic 6-4 6-4.

France’s Gael Monfils defeated Ukrainian qualifier Sergei Bubka – the boyfriend of women’s No 1, Victoria Azarenka – 6-4, 6-4 in 78 minutes.

Monfils next faces Argentine 21st seed Juan Monaco.

Serena Williams breezed into the fourth round with a 6-2, 6-1 win over Italian number 21 seed Roberta Vinci. Williams, whose five Miami triumphs tie her with Steffi Graf for the record, said she was still hungry for more.

Maria Sharapova progressed easily, beating American qualifier Sloane Stephens 6-4, 6-2, but former number one and twice Miami winner Kim Clijsters was eliminated when she was beaten by fellow Belgian Yanina Wickmayer 6-4 7-6 in their third round clash.

Fourth-seeded Caroline Wozniacki beat Czech Petra Cetkovska 6-3 7-5, while eighth-seeded Li Na of China won the last four games of each set to beat another Czech, Iveta Benesova, 7-5 6-2.
