Switzerland's Roger Federer continued his strong start to the 2014 season with another victory on Friday, defeating big-serving Croat Ivo Karlovic 6-4, 7-6 (7-4) to advance to the third round of the Sony Open Tennis event in Miami.

The fifth-ranked Swiss, who had defeated Karlovic in 10 of their previous 11 contests, completely dominated his service games en route to the routine win in an hour and 14 minutes.

The 32-year-old Federer put 75 percent of his first serves in play and won 94 percent of those points against his slow-footed opponent. The Swiss was just as dominant on his second serve, winning 12 of those 13 points.

Karlovic, 35, struck 13 aces to keep himself in the match, but his serve abandoned him when he needed it most in the second-set tiebreaker.

Federer, who won this event in 2005 and 2006, will next play the winner of the second-round match between Spain's Fernando Verdasco and Dutchman Thiemo De Bakker.

The Swiss, buoyed by a racquet change and new coach Stefan Edberg, reached the semifinals of the Australian Open, won a title in Dubai in February and reached the final of last week's BNP Paribas event in Indian Wells, California.

In other action Friday afternoon, Spanish world No. 4 David Ferrer cruised to a comfortable 6-4, 6-0 victory over Russia's Teymuraz Gabashvili.

Coming back from a leg injury that forced him to pull out of Indian Wells, Ferrer battled through a tough first set in which he needed to stave off five break points and then completely dominated the second set with his return game.

Gabashvili got away with a low first-serve percentage in the first set, but Ferrer made him pay for too many second serves in the latter part of the match.

After winning 70 percent of his second-serve points in the first set, the Russian managed just a 27 percent winning percentage on those points in the second set and the match turned into a rout.

In other second-round results Friday afternoon, Spain's Tommy Robredo edged Austrian Dominic Thiem 6-4, 7-6 (10-8), Frenchman Richard Gasquet topped Colombia's Alejandro Gonzalez 7-6 (9-7), 6-4, South Africa's Kevin Anderson defeated Argentina's Horacio Zeballos 6-4, 6-3, and Germany's Florian Mayer trounced Croatia's Ivan Dodig 6-3, 6-2.

In the women's draw, Spain's Garbiñe Muguruza, the No. 30 seed, was upset 3-6, 7-6 (8-6), 6-1 in the second round by Croatia's Ajla Tomljanovic.

The Sony Open Tennis tournament is one of the biggest hard-court events on the ATP and WTA calendars. EFE
