Murray, Djokovic Secure Berths at Wimbledon

Defending champion Andy Murray and top-seeded Novak Djokovic each secured berths in the quarterfinals at Wimbledon with straight-set victories Monday. The  third-seeded Murray downed No. 20 seed Kevin Anderson 6-4, 6-3, 7-6 (8-6) under the closed roof on Centre Court, while the 2011 Wimbledon champ Djokovic cruised to a 6-3, 6-4, 7-6 (7-5) decision over 14th-seed Jo-Wilfried Tsonga. Australian Open champ Stan Wawrinka advanced  to the fourth round earlier in the day with a 6-3, 6-3, 6-4 verdict over Denis Istomin.

One major upset took place on the women's side Monday, with fourth-seeded and 2012 Wimbledon runner-up Agnieszka Radwanska dealt a stunning 6-3, 6-0 defeat by No. 22 seed Ekaterina  Makarova in the fourth round. 2011 champion Petra Kvitova did earn a spot in the quarterfinals, however, with the sixth-seeded Czech blowing past Peng Shuai 6-3, 6-2. Ana Ivanovic and Caroline Wozniacki also exited the draw on Monday, with 2013 finalist Sabine Lisicki outlasting Ivanovic 6-4, 3-6, 3-1 in a third-round match and the 16th-seeded Wozniacki falling to Barbora Zahlavova Strycova in straight sets. Alize Cornet, fresh off her upset of World No. 1 Serena Williams, lost to 13th-seeded Canadian Eugenie Bouchard in another fourth-round bout.
