Roger Federer continued his US Open form at Flushing Medows on Saturday, while Andy Murray remained in the hunt for his first grand slam crown.

Federer cruised past Fernando Verdasco 6-3 6-4 6-4 in two hours and two minutes, blasting seven aces and 30 winners against the 25th-seeded Spaniard.

Federer has not lost a set at the US Open this year, as he moves closer to a sixth title at the National Tennis Center.

The Swiss next faces American 23rd seed Mardy Fish, who beat Gilles Simon, the French 16th seed, 6-1, 5-7, 7-6 (7/5), 6-3.

Murray, who won Olympic gold last month, recovered from a mid-match lapse to defeat Spain’s Feliciano Lopez 7-6 7-6 4-6 7-6 in three hours and 53 minutes to reach the fourth round.

Third seed Murray next plays 15th-seeded Canadian Milos Raonic, who beat American James Blake 6-3 6-0 7-6 on the back of 29 aces to become the first Canadian to make the last 16 in 24 years.

Eleventh seed Nicolas Almagro kept Spanish hopes alive when he reached the fourth round for the first time with a 7-6 (7/3), 6-7 (4/7), 7-6 (7/2), 6-1 win over American wildcard Jack Sock.

Almagro will meet Czech sixth seed Tomas Berdych, who defeated American 27th seed Sam Querrey 6-7 (6/8), 6-4, 6-3, 6-2.

Croatian 12th seed Marin Cilic, a quarterfinalist in 2009, ended Asian hopes in the singles when he ousted Japanese 17th seed Kei Nishikori 6-3, 6-4, 6-7 (3/7), 6-3.

Cilic will next face unseeded Slovak Martin Klizan who beat doubles partner Jeremy Chardy, the French 32nd seed, 6-4, 6-4, 6-4.

Three-time women’s champion Serena Williams went level with sister Venus on 61 US Open career wins when she coasted into the fourth round of the US Open on Saturday.

Olympic and Wimbledon champion Williams won eight games in succession to claim a 6-4, 6-0 win over Russia’s world 42 Ekaterina Makarova, the woman who knocked her out of the Australian Open this year.

Williams, the fourth seed, fired 31 winners and eight aces and will next face unseeded Czech Andrea Hlavackova, who beat Maria Kirilenko of Russia, the 14th seed, 5-7, 6-4, 6-4.

Polish second seed and Wimbledon runner-up Agnieszka Radwanska matched her best US Open performance by also reaching the last 16 with a 6-3, 7-5 win over error-plagued Serb 30th seed Jelena Jankovic, the 2008 runner-up. Radwanska goes on to face Italian 20th seed Roberta Vinci for a place in the quarterfinals.

Vinci reached the last 16 for the first time with a 6-2, 7-5 win over Slovakia’s 13th seed Dominika Cibulkova, a quarterfinalist in 2010.

Former world number one and 2008 French Open champion Ana Ivanovic reached the last 16 for the fourth time with a 6-7 (4/7), 6-4, 6-2 win over highly-regarded American teenager Sloane Stephens.

The Serb 12th seed will next face Bulgaria’s Tsvetana Pironkova who saw off Spain’s Silvia Soler-Espinosa 6-1, 6-7 (3/7), 6-3.

German sixth seed Angelique Kerber, a semifinalist in 2011, eased past Olga Govortsova of Belarus 6-1, 6-2, and now meets French Open runner-up Sara Errani, the 10th seeded Italian, who defeated Russian qualifier Olga Puchkova 6-1, 6-1.
