The first match-winner this year is Bosnian Damir Dzumhur, in the men's draw. He was up two sets against Mikhail Youzhny when the Russian retired at the start of the third. Youzhny was a quarterfinalist in 2010.
On the women's side, the first winner is Teliana Pereira. The Brazilian qualifier chomped through Fiona Ferro, a 326th-ranked French wild card, in 65 minutes, winning 6-3, 6-2.

Out on Court 2, Phillip Kohlschreiber, seeded 22nd, has torn through his first set against Japan's Go Soeda, winning 6-1. Kohlschreiber (aged 31) and Soeda (30) are among 39 men aged 30 or over in the Roland Garros main draw. That is a Grand Slam record.
Another veteran, 32-year-old Mikhail Youzhny, is off to a bad start on Court 6, losing his first set 6-2 against Bosnian Damir Dzumhur.
The most golden of oldies, 33-year-old Roger Federer, follows Simona Halep on center court. Last year's losing women's finalist is up against Evgenia Rodina, winning the first set 7-5.

Here we go again. On a sunny Sunday morning, play is about to start at the French Open, as grounds crews finish watering the center court.
The weather forecasts are excellent, with temperatures expected to reach 22 degrees Celsius (72 F) in the afternoon.
Last year's runner-up Simona Halep will open play on Center Court. The third-seeded Romanian player is taking on Russian Evgenia Rodina before Roger Federer starts his bid for an 18th Grand Slam title against lucky loser Alejandro Falla.
