The French Open suffered its first complete washout since 2000 Monday when all scheduled matches were canceled due to heavy rain. "Due to weather, there will be no matches played at #RG16 today," said the Roland Garros Twitter feed. There could be more problems Tuesday with further rain forecast throughout the day before conditions brighten Wednesday. Eight last-16 matches planned for Monday plus two more which had already been held over from Sunday night will now be played Tuesday. Three quarterfinals are also due to take place Tuesday — Andy Murray against Richard Gasquet and defending champion Stan Wawrinka in the men's event while Shelby Rogers was to face Garbine Muguruza in the women's singles. Play had been set to get underway at 1100 (0900GMT) Monday but was eventually called off just before 1400 (1200GMT). "All cancelled for today — rain, rain go away," tweeted Czech seventh seed Tomas Berdych who was due to face former runner-up David Ferrer of Spain for a last-eight spot. This year's Roland Garros was hit by rain delays on the opening Sunday when just 10 of the scheduled 32 opening round ties were completed in a little over four hours of play. The second day was then hit by another two-and-a-half hour delay. That in turn pushed 12 of the scheduled 66 matches back to the first Tuesday. There was a two-and-a-half hour stoppage Saturday followed by another hour on Sunday which meant that the planned last-16 program remained unfinished. Under the original schedule, all of the fourth round was to be completed Monday, leaving Tuesday and Wednesday for the quarterfinals. But if there are further delays Tuesday, world No. 1 Novak Djokovic, who is chasing a first French Open to complete the career Grand Slam, could end up playing his last-16 tie Wednesday, quarterfinal Thursday and semifinal Friday. Roland Garros organizers are planning a roof for the showpiece Philippe Chatrier Court but that will not be ready until 2020. Djokovic is poised to become the first man to win $100 million in prize money if he makes the quarterfinals for the 10th time. Djokovic is also bidding to reach the quarterfinals for the 28th straight Grand Slam and take sole occupancy of second place ahead of Jimmy Connors for the most consecutive last-eight appearances at the majors. With $99,673,404 banked in prize money at the start of Roland Garros, the 29-year-old Djokovic can cross the $100 million barrier by making the last-eight. A place in the quarterfinals is worth 294,000 euros ($326,722) and that will just take the Serb into the $100,000,000 bracket. Roger Federer is Djokovic's closest rival in the prize money stakes on $98,011,727 but the Swiss is sitting out Roland Garros through injury. — Agencies
