the quarterfinals at three of the last four Slams, might face third-ranked and Davis Cup teammate Stan Wawrinka in an all-Swiss encounter in the quarters.
Sharapova, who defeated Serena Williams in the 2004 final at the age of 17 to win her only Wimbledon title and first Grand Slam championship, will open against Samantha Murray. Williams will take on Anna Tatishvili.
If Williams and Sharapova get to the quarterfinals, it will set up their 19th career meeting. Williams leads 16-2 and has not lost to her Russian rival since the 2004 WTA Championships.
The other potential women’s quarterfinals are: Simona Halep vs. Jelena Jankovic, Victoria Azarenka vs. Agnieszka Radwanska, and Petra Kvitova vs. Li Na.
Williams is coming off a second-round loss at the French Open, where Sharapova won her fifth major title. After Williams’ previous early exit at the French Open in 2012, when she lost in the first round, she went on to win Wimbledon and the U.S. Open.
Williams could face an intriguing fourth-round match against Eugenie Bouchard, the 20-year-old Canadian who has reached the semifinals of both Grand Slams so far this year. But the 13th-seeded Bouchard faces a challenging first-round opponent in Daniela Hantuchova.
In the absence of defending champion Marion Bartoli, who retired less than six weeks after winning her sole Grand Slam title, last year’s runner-up finalist Sabine Lisicki will open Centre Court play on Tuesday against Julia Glushko.
The third-seeded Halep, who achieved a breakthrough performance at the French Open by reaching her first major final, is in the same quarter as former No. 1 Ana Ivanovic.
