Novak Djokovic and Roger Federer are the big draws on middle Saturday at Wimbledon as they look progress to the last 16.
Serb Djokovic is second on Centre Court with the world number four and second seed facing Ernests Gulbis of Latvia.
Switzerland's Federer, a seven-time Wimbledon champion, then follows against Mischa Zverev.
Fellow German and world number one Angelique Kerber plays American Shelby Rogers in the second game on court two.
Kerber will likely need to reach the final to retain her place at the top of the WTA rankings.
Any Britons in action?
Jamie Murray and Switzerland's Martina Hingis are due on court after 17:00 BST for their second-round mixed doubles match.
They are the top seeds at Wimbledon, with Scot Murray fifth in the men's doubles rankings and Hingis third in the women's. They face British pair Neal Skupski and Anna Smith.
Meanwhile, it is a busy day for Heather Watson and Naomi Broady, who are both twice in doubles action.
British number two Watson, who was beaten by Victoria Azarenka in the third round of the singles tournament on Friday, teams up with Broady to play Belgium's Kirsten Flipkens and Indian 2015 doubles champion Sania Mirza in round two of ladies' doubles.
Watson then partners Henri Kontinen of Finland against Aisam-ul-Haq Qureshi of Pakistan and Germany's Anna-Lena Gronefeld in the second round of mixed doubles.
Broady and brother Liam face Czech pair Roman Jebavy and Lucie Hradecka in the final mixed doubles round two match on court 18.
