Paris - With more bad weather expected on Tuesday, French Open organisers are trying to get as many matches as possible out of the way before the rain.
After Monday's complete washout at the clay-court Grand Slam, matches will start at 11:00 a.m. - three hours earlier than initially planned - and be spread over more courts.
Top-ranked Novak Djokovic takes on 14th-seeded Roberto Bautista Agut in the first match on Court Philippe Chatrier, playing for a place in the quarterfinals.
They will be followed by defending champion Serena Williams in her delayed fourth-round match against 18th-seeded Elina Svitolina.
The first men's quarterfinals are also scheduled: Second-seeded Andy Murray against Richard Gasquet, and defending champion Stan Wawrinka against Albert Ramos-Vinolas.
