At the French Open, top-ranked Andy Murray has never lost to a player ranked as low as No. 50 Martin Klizan, his opponent in the second round on Thursday.

Klizan was involved in a controversy in his previous match after Laurent Lokoli accused him of faking injuries during their match, and refused to shake his hand.

Among other men in action at Roland Garros are No. 3 Stan Wawrinka, No. 7 Marin Cilic and No. 18 Nick Kyrgios.

All chasing a first Grand Slam title, second-seeded Karolina Pliskova, No. 3 Simona Halep and No. 5 Elina Svitolina headline women's play. Pliskova faces Ekaterina Alexandrova, Halep takes on Tatjana Maria, and Svitolina meets Tsvetana Pironkova.
