Who are you? Wimbledon’s challengers
Here is a look at the men and women trying to upset the stars at Wimbledon in the first round:
Roger Federer v Dusan Lajovic (Federer leads series 1-0)
Best run at the majors was a last-16 spot at Roland Garros four years ago where it took Rafael Nadal to stop him. The Serb was beaten by Federer in straight sets in the second round of Wimbledon in 2017.
Rafael Nadal v Dudi Sela (Nadal leads series 2-0)
Ranked 129, the 33-year-old Sela has just three wins on the main tour in 2018 but made the last-16 at Wimbledon in 2009 where he was knocked out by Novak Djokovic.
Novak Djokovic v Tennys Sandgren (First meeting)
World No. 56 Sandgren of the US stunned the sport by making the Australian Open quarter-finals in January knocking out Stan Wawrinka and Dominic Thiem. Made the final in Houston this year but will be making his Wimbledon debut.
Andy Murray v Benoit Paire (Murray leads 2-0)
Explosive and colourful, the 29-year-old Paire was a point away from beating Federer in the Halle second round this month. Two years earlier, the Frenchman said he hated Wimbledon. Despite that, still made the fourth round at Wimbledon in 2017 where he lost to Murray.
Serena Williams v Arantxa Rus (First meeting)
Dutch world 107 Rus made the third round at Wimbledon in 2012 but failed to get out of qualifying on her last three visits.
Simona Halep v Kurumi Nara (Halep leads series 1-0)
Nara, standing at just 5ft 1in (1.55m) is ranked 101 but the Japanese has a Grand Slam pedigree — in 2017, she defeated Svetlana Kuznetsova in the second round of the US Open. Made the third round on her Wimbledon debut in 2010.
Garbine Muguruza v Naomi Broady (Muguruza leads 1-0)
British wild card Broady, ranked 138, has just one win on the WTA Tour this year. It was on that second-level that Broady faced 2017 Wimbledon champion Muguruza in their only meeting at Wrexham in Wales in 2011.
Maria Sharapova v Vitalia Diatchenko (Sharapova leads 1-0)
Ranked at 132, Diatchenko, 27, has been plagued by injuries. This year, the Russian qualified for Wimbledon and returned to the main draw of a major for the first time since the 2016 US Open.
