Murray, Berdych winners in Key Biscayne

Reigning U.S. Open champion Andy Murray and Tomas Berdych were among the winners in Saturday's second round of the Sony Open.

The second-seeded Murray had little difficulty in his matchup with Australia's Bernard Tomic, as he earned a 6-3, 6-1 victory that lasted just under 57 minutes.

Berdych, though, had a few more problems in his matchup with Spaniard Daniel Gimeono-Traver. The fourth-seeded Czech dropped the first set before rallying to win a tiebreak in the second, then cruised in the final set in the 5-7, 7-6 (7-3), 6-2 victory.

Sixth-seeded Frenchman Jo-Wilfried Tsonga battled through a tough first set before earning a 7-6 (8-6), 6-3 win over Serbia's Viktor Troicki, while eighth-seeded Richard Gasquet posted a 7-5, 6-2 triumph over Belgian qualifier Olivier Rochus.

Tsonga will next play Jarkko Nieminen in the third round. The Finnish veteran eased past 27th-seeded Slovakian Martin Klizan, 6-2, 6-2.

Ninth-seeded Croat Marin Cilic posted a 6-2, 7-6 (8-6) win over Santiago Giraldo of Colombia, while 14th-seeded Canadian Milos Raonic was an easy winner with a 6-2, 6-4 decision over Frenchman Guillaume Rufin.

Spain's Nicolas Almagro, seeded 10th, blew past Argentine wild card Guido Pella 6-0, 6-3 in just 48 minutes and 29th-seeded Bulgarian Grigor Dimitrov advanced when his opponent, Italian Simone Bolelli, retired in the second set with an injury.

Other winners Saturday included 16th-seeded Andreas Seppi of Italy and American Sam Querrey. Seppi needed three sets to dispose of Slovenia's Aljaz Bedene, 7-5, 5-7, 7-5, while the No. 17 seed Querrey rallied from a set down to beat Poland's Lukas Kubot, 4-6, 6-3, 6-3.

Russia's Mikhail Youzhny, the 28th seed, needed all three sets to take out Yen-Hsun Lu of Chinese Taipei 6-3, 1-6, 6-0, while 20th-seeded American John Isner rallied from a first-set loss to take a 4-6, 7-5, 7-6 (7-5) victory over Ivan Dodig of Croatia

Three minor upsets also occurred on Saturday. Belgian David Goffin toppled big-serving 18th-seeded German Philipp Kohlschreiber, 7-6 (7-5), 4-6, 6-2; Brazilian Thomaz Bellucci took a 7-6 (7-5), 3-6, 6-3 victory over 21st-seeded Pole Jerzy Janowicz; and Colombian Alejandro Falla came through with a 6-3, 7-6 (8-6) verdict over 25th-seed Fernando Verdasco.
