Rocky start for Petra Kvitova

Controversial Australian Nick Kyrgios and two-time Wimbledon champion Petra Kvitova reached the French Open second round on Sunday as Roland Garros got off to a damp, chilly start.

Kyrgios overcame a first set code violation to defeat Italy’s Marco Cecchinato 7-6 (8/6), 7-6 (8/6), 6-4.

The 17th seed picked up the warning for screaming at a ball boy on a shivering Court One where the temperature refused to budge above 15 degrees.

Kyrgios insisted he only screamed at the youngster during the first set tiebreak because he wanted his towel and needed to make his voice heard.

He then accused umpire Carlos Ramos of “unbelievable bias” for dishing out the violation.

Czech 10th seed Kvitova survived a scare to beat Danka Kovinic of Montenegro 6-2, 4-6, 7-5.

The two-time Wimbledon champion was two points away from defeat when she trailed the world number 57 at 4-5 in the decider.

But she claimed the next three games and goes on to face Taiwan’s Su-Wei Hsieh for a place in the last 32.

Kvitova, a semi-finalist in Paris in 2012, committed 10 double faults in a typically rollercoaster display against an opponent who made the Istanbul final on clay. Japanese fifth seed Kei Nishikori was leading 6-1, 5-4 against Italy’s Simone Bolelli when rain stopped play.
