Williams sisters star on Wimbledon’s manic Monday

Azarenka, a two-time Australian Open champion, has lost 17 games and will next meet 30th-seeded Belinda Bencic of Switzerland.

Serena Williams is still on track for a true Grand Slam.

Williams, who has won 20 major titles in her career, has already won the Australian Open and French Open this season.

If Serena Williams and Maria Sharapova are both on top form this should be an unbelievable contest.

Ex- world number one, Jelena Jankovic, who put out defending champion Petra Kvitova on Saturday, takes on Agnieszka Radwanska, the 2012 runner-up.

Vandeweghe won, 7-6 (1), 7-6 (4), and was her own worst critic afterward.

Radwanska will face No. 20 Garbine Muguruza of Spain in the semifinals on Thursday.

Sisters Serena and Venus Williams kick off the action on Centre Court today, and they’re no strangers to facing each other. She has never beaten Serena at a Grand Slam, though, and on grass Williams is a different prospect. Had Rafael Nadal not been upset in the second round, he could’ve been in line to face Murray in Wednesday’s quarterfinals match.

Novak Djokovic of Serbia plays a forehand in his Gentlemens Singles Quarter Final match against Marin Cilic of Croatia during day nine of the Wimbledon Lawn Tennis Championships at the All England Lawn Tennis and Croquet Club on July 8, 2015 in London, England. Play on the two main courts is scheduled to start at 1 p.m.

Novak Djokovic, Roger Federer, Andy Murray and Stan Wawrinka are all expected to win their respective matches and advance to the semifinals.

The first two sets ended with Anderson edging nervy tiebreaks, before Djokovic revved into gear storming through the third 6-1 and clinching the fourth 6-4 to leave the match in the balance and the crowd wanting more. The last player to win all four major titles in the same year was Steffi Graf in 1988.

Fourth seed Maria Sharapova, the 2004 champion, faces Zarina Diyas of Kazakhstan.

Andy Murray got past a barrage of big serves from the biggest server, Ivo Karlovic of Croatia, before winning and keeping the hopes of the Brits alive for a second men’s Wimbledon title in three years. It was the previous year, in 2010, when she last reached the quarterfinals at Wimbledon. A win today would make her first quarterfinals appearance since 2011.

Keeping up with everything going on at Wimbledon is a task of huge proportions – with games in the first week in particular stretching across the 19 courts within the grounds.

Vandeweghe’s compatriot Madison Keys is hotly tipped to one day emulate her coach Lindsay Davenport and become a Wimbledon champion. Then he went back out to play doubles with Jack Sock of the USA and lost another long five-setter. The top-seeded Serb will have to finish his fourth-round match against Kevin Anderson on Tuesday after play was suspended Monday because of darkness at two sets apiece.

Djokovic’s comeback included shaking off a blown 4-0 lead in the second-set tiebreaker.

The tarps are off and players are back on court at Wimbledon.
