Rain starts to come down at Wimbledon

But the world wants to know what’s happening, and the task of capturing and recording every single drop shot, volley and epic five-set comeback falls to IBM, the official technology partner at the All England Lawn Tennis Club.

That’s what will happen Monday when Serena Williams plays older sister Venus Williams for the sixth time at the grass-court Grand Slam in southwest London.

Serena Williams is still on track for a true Grand Slam. She needs the Wimbledon and US Open titles to complete the set and become the first person to win a calendar-year Grand Slam since Steffi Graf in 1988.

Sharapova, the 2004 Wimbledon champion, has lost only 15 games through three rounds and will next face Zarina Diyas of Kazakhstan. Federer holds a 12-11 advantage, and he beat Murray in a Wimbledon final in 2012.

The 13th-seeded Pole, who lost in the 2012 final, beat Madison Keys of the United States 7-6 (3), 3-6, 6-3 Tuesday in the quarterfinals.

Before Wimbledon, she had not been past the third round of any major. McIlroy ended their relationship previous year.

While this contest will not be the main attraction playing out on Centre Court Thursday, there’s plenty of intrigue surrounding Radwanska and Muguruza’s matchup.

Three American women, including Williams, are in the quarterfinals. Play on the two main courts is scheduled to start at 1 p.m. Blockbuster-type match-ups between stars Andy Murray and Roger Federer, as well as Novak Djokovic and Stan Wawrinka, were potentially on tap as the tournament headed into its final stretch.

Simon has only once before reached the quarterfinals at a major tournament, getting that far at the 2009 Australian Open. The last player to win all four major titles in the same year was Steffi Graf in 1988. Azarenka beat 18-year-old Belinda Bencic of Switzerland 6-2, 6-3, but is 0-9 against Williams in Grand Slam events. She has plenty of experience, and is hoping it will suit her well against Muguruza – the first Spanish women since 1997 to reach a Wimbledon semifinal. She reached the semifinals at the All England Club the next two years, but only once more since then, when she lost to Petra Kvitova in the 2011 final.

Vandeweghe was playing in her first Grand Slam quarterfinal match.

LONDON (AP) – One five-time Wimbledon champion is guaranteed to reach the quarterfinals.

Novak Djokovic has lost another set at Wimbledon.

In the next round, Cilic will face either Novak Djokovic or Kevin Anderson. But the top-seeded Serb can still defend his title at Wimbledon, a victory that would give him a third championship at the All England Club.

It wouldn’t have been a surprise to see Djokovic fist-pumping after Gasquet’s performance Wednesday.

Roger Federer is the only current player with more Wimbledon singles titles than a Williams, and the seven-time champion is one away from a record-setting eighth. Vandeweghe will next face fourth-seeded Maria Sharapova, who won Monday to advance to the quarterfinals for the first time since 2011.

Novak Djokovic stepped out onto Court 1 on Tuesday to resume his match with the sun shining overhead.

Djokovic’s next opponent will be Kevin Anderson, a 14th-seeded South African who has never been past the fourth round at a Grand Slam tournament.

On Centre Court, Maria Sharapova and CoCo Vandeweghe were warming up before heading inside to escape the rain.

The start of play on the outside courts was put back by 45 minutes from 13:00 to facilitate the observance of the national minute’s silence at 13:30.

On July 7, 2005, four Islamist suicide bombers killed themselves and 52 innocent victims on three Underground trains and a bus.
