Wawrinka, Azarenka shown the door

Paris: Switzerland's 23rd seed Stan Wawrinka was knocked out in the first round of the French Open, losing 2-6, 6-3, 6-4, 6-7, 3-6 to Spain's Guillermo Garcia-Lopez at the French Open here on Monday.

Two-time Grand Slam winner Victoria Azarenka crashed out in the first round losing 5-7, 5-7 to Katerina Siniakova on Monday. 

She is playing only her fifth tournament of the year after a legal battle over the custody of her son.  

Spanish tennis player Carla Suarez Navarro, world No 23 sailed through the first round with a 6-0, 6-1 win over Croatia's Ana Konjuh in just 42 minutes. 

The 29-year-old prevailed over the world No. 104 for the second time in two career encounters, winning 86 percent of her first serves, compared to Konjuh's 32 percent.

After losing the first set, Azarenka showed signs of a comeback, winning a fierce-hitting baseline exchange to go to 2-2. But she was unable to build momentum even as her Czech opponent lost her cool over a handful of disputed line calls.

Former world number one Azarenka has endured a tough return to Europe's clay courts, losing in the second round at the Madrid Open before being dumped out of the first round in Rome. 

She is currently ranked 84 in the world. Azarenka won the Australian Open in 2012 and 2013. Her best performance at Roland Garros was in 2013 when she lost in the semi-finals to Russia's Maria.

Serbia's Novak Djokovic defeated Rogerio Dutra Silva of Brazil 6-3, 6-4, 6-4. Although he did not put on a stellar performance, Djokovic was good enough to get past the world No 134 in two hours and five minutes.

Spaniard Lara Arruabarrena Vecino, ranked No 91, pulled off an upset victory over world No 37 Timea Babos of Hungary 7-6 (7-5), 6-3 in 87 minutes to earn her third victory in as many career encounters with Babos. Arruabarrena is next up against world No. 

8 Petra Kvitova of Czech Republic, who knocked out Veronica Cepede Royg of Paraguay 3-6, 6-1, 7-5.

Kvitova came within three points of falling in the first round of the French Open before three successive aces and her nerves of steel carried her to a  3-6, 6-1, 7-5 win over little-known Paraguayan Veronica Cepede Royg on Monday.

The Czech, who suffered career-threatening injuries on her playing left hand after being attacked in her home by a knife-wielding intruder in December 2016, arrived in Paris on the back of an 11-match winning streak.
