Share !Wimbledon, England (SportsNetwork.com) - Roger Federer continued his bid for a record eighth Wimbledon title with a 6-4, 6-4, 6-7 (5-7), 6-2 third-round win over Sam Groth on Saturday. Federer faced little pressure from Groth on return as he lost only five points on serve through the first two sets. There were no service breaks in the third set, but a double fault by Federer gave Groth a 4-3 lead in the tiebreak. Groth eventually won the tiebreak when Federer fired a forehand wide, but he was broken while falling behind 3-0 in the fourth set. The second-seeded Swiss broke again in the final game to clinch his 19th straight victory over an Australian opponent at a Grand Slam. Bidding for his second Wimbledon title in three years, third-seeded Andy Murray defeated Italian Andreas Seppi 6-2, 6-2, 1-6, 6-1 to advance to the fourth round. Former Wimbledon finalist Tomas Berdych overcame a slow start to beat Spaniard Pablo Andujar 4-6, 6-0, 6-3, 7-6 (7-3). The sixth-seeded Berdych lost to Rafael Nadal in the 2010 final. The Czech player next faces Frenchman Gilles Simon, who needed well over three hours to send down countryman Gael Monfils by a 3-6, 6-3, 7-6 (8-6), 2-6, 6-2 count in Saturday's late match. U.S. Open champion Marin Cilic completed a five-set win over 17th-seeded American John Isner. The match was suspended Friday because of darkness at 10- all in the fifth set. The ninth-seeded Croatian won the first two games when the match resumed on Saturday to finish off the four-plus hour marathon. Another Croatian player, Ivo Karlovic, joined Cilic in the round of 16, beating two-time Wimbledon semifinalist Jo-Wilfried Tsonga 7-6 (7-3), 4-6, 7-6 (7-2), 7-6 (11-9). Other men advancing were 20th-seeded Spaniard Roberto Bautista Agut, who beat Georgia's Nikoloz Basilashvili 7-6 (7-4), 6-0, 6-1, and 22nd-seeded Serbian Viktor Troicki, who ousted German Dustin Brown 6-4, 7-6 (7-3), 4-6, 6-3. The 102nd-ranked Brown, a qualifier, stunned the 10th-seeded Nadal in the second round. Another result saw Canadian Vasek Pospisil outlast Brit wild card James Ward in five sets.
