Seven-time champion Roger Federer faces Dusan Lajovic in the second round of Wimbledon 2017 on Thursday, while second seed Novak Djokovic plays Adam Pavlasek.
Both well-fancied for the title, Federer and Djokovic had little trouble in their first-round matches as they were handed walkovers after the respective retirements of Alexandr Dolgopolov and Martin Klizan.
In the women's draw, top seed and world No. 1 Angelique Kerber faces a tough second-round clash against former Wimbledon semi-finalist Kirsten Flipkens.
Meanwhile, Karolina Pliskova and Caroline Wozniacki are both also in action against Slovakia's Magdalena Rybarikova and Bulgarian Tsvetana Pironkova, respectively.

Federer was cruising at 6-3, 3-0 in his first-round match when Dolgopolov called it a day due to an ankle injury after just 43 minutes.
It proved an easy day for the Swiss legend, but he will likely be eager to get a full run-out under his belt against Serbian Lajovic.
Federer, 35, has never before faced the 27-year-old in competition. But, while Lajovic is an unknown quantity for the 18-time Grand Slam winner, there is little chance of an upset.
Wimbledon is Federer's home from home. He is arguably the greatest grass-court player of all time and is still just about at the top his game despite his advancing years—see his Australian Open triumph earlier this year.
Lajovic enjoyed a fine straight-sets win over Greek Stefanos Tsitsipas in his first-round match and is likely to raise his game to face the legendary Federer.
But anything other than an easy win for the former champion would be a big surprise on the fourth day of Wimbledon 2017.
The same would also be true in Djokovic's clash with world No. 136 Pavlasek—the Serb is a three-time champion in SW19.
It has not been the best of years for the world No. 4, but he showed his form is good on grass by winning the title at Eastbourne last week.
His first-round match against Klizan lasted just 40 minutes before a calf injury for the Slovak saw the match ended with Djokovic 6-2, 2-0 to the good.
As with Federer and Lajovic, Djokovic and Czech 22-year-old Pavlasek have never played each other before. But Djokovic has too much quality and experience to be downed in the second round on Thursday.
Kerber, 29, faces a much greater challenge. The German won two Grand Slam titles in 2016 and reached the final of Wimbledon—before being beaten by Serena Williams.
In 2017, though, her Australian Open defence ended at the fourth round, and she was knocked out in the first round at the French Open for the second consecutive year.
Kerber downed American Irina Falconi in the first round but, if she is to keep her No. 1 ranking, she must go very deep at Wimbledon this year, per TSN Tennis:
Flipkens will be a challenging opponent, and it would be no surprise were the clash between the pair to go the distance, as it did at Wimbledon 2014, when Kerber beat the Belgian 3-6, 6-3, 6-2 in the third round.
