Reigning Olympic and US Open champion Andy Murray advanced to the third round of the WTA and ATP Miami Masters after routing Australia’s Bernard Tomic 6-3 6-1 on Saturday.
Tomic managed to win only 10 points in the final set of the 56-minute match.
World No.2 Murray, who lost to top-ranked Novak Djokovic in last year’s final, will face either Italy’s Simone Bolelli or Bulgarian 29th seed Grigor Dimitrov in his next match.
The Scotsman hopes to claim his second Miami crown after lifting the 2009 trophy with a victory over Djokovic in the final.
Murray remained perfect against Tomic, the youngest player in the ATP top 100 at age 20, after having won their only prior meeting 6-3 6-2 last year in a semi-final at Brisbane.
Murray broke in the fifth game and then held serve for a 4-2 lead, taking full advantage of 14 unforced errors in the first six games by Tomic.
Tomic netted a backhand to hand Murray a second break, and the first set, in the ninth game of the match.
The Aussie hit back-to-back double faults to surrender a break to Murray and fall behind 3-1 in the second set. Murray broke for the fourth time to seize a 5-1 lead and then held to take the match, closing it out with his eighth ace.
Defending champion Agnieszka Radwanska outlasted Slovakia’s Magdalena Rybarikova 7-6 (7-5) 2-6 6-3. The Polish fourth seed has a chance to become the first repeat women’s winner at Miami since Serena Williams in 2007-2008.
Radwanska will next face Sloane Stephens who advanced when Venus Williams withdrew with a back injury.
French sixth seed Jo-Wilfried Tsonga and Chinese fifth seed Li Na advanced with straight-set triumphs in hot and humid conditions.
Tsonga defeated Serbia’s Viktor Troicki 7-6 (8-6) 6-3 to reach the third round while Li smacked 19 winners and fought off a late comeback bid to defeat American Varvara Lepchenko 6-2 6-4 and reach the fourth round.
Li had been sidelined for seven weeks after hurting her left ankle in the Australian Open final, which she lost to Victoria Azarenka, but she improved to 16-2 this season and booked a round-of-16 date with Spain’s Garbine Muguruza, who upset Danish ninth seed Caroline Wozniacki 6-2 6-4.
Tsonga will face either Finland’s Jarkko Nieminen or Slovakian Martin Klizan in the next round.
French eighth seed Richard Gasquet dispatched Belgian Olivier Rochus 7-5 6-2 to reach a third-round match against either Taiwan’s Lu Yen-Hsun or Russia’s Mikhail Youzhny.
US 17th seed Sam Querrey rallied to eliminate Poland’s Lukasz Kubot 4-6 6-3 6-3 in one hour and 47 minutes. Querrey will next face either Canadian 14th seed Milos Raonic or Frenchman Guillaume Rufin.
Belgium’s David Goffin ousted German 15th seed Philipp Kohlschreiber 7-6 (7-5) 4-6 6-2.
Next in Goffin’s path will be the winner of a later match between Spanish 10th seed Nicolas Almagro and Argentina’s Guido Pella.
