Men's round-up: Tomas Berdych storms into second round

The 29-year-old Czech powerhouse, boasting a top-four seeding at a major for the first time in his career, brushed aside Japanese qualifier Yoshihito Nishioka 6-0 7-5 6-3 -- so avoiding a sixth first-round fall at the French Open.

Nishioka was one of five Japanese men to start in the main draw, the most since 1967, but only highly-fancied Kei Nishikori remains two days into the claycourt grand slam.

Berdych, a member of the world's top 10 for five years but with only one grand slam final to his name, at Wimbledon in 2010 when he lost to Nadal, was far too streetwise for Nishioka and was only briefly tested in the second set.

"I'm feeling well. I'm feeling physically, mentally strong, and that's the best possible start that I can have," Berdych told reporters. "Just now be patient, keep working for the two weeks, and try to go as far as I can."

Spain's Feliciano Lopez, the men's 11th seed, became the highest casualty so far, losing 6-3 7-6(9) 6-3 to Russian Teymuraz Gabashvili.

Croatian Borna Coric, 18, beat American Sam Querrey 7-6 (8) 6-3 0-6 6-3 while Australian wildcard Thanasi Kokkinakis, 19, put out Georgian Nikoloz Basilashvili.

Nick Kyrgios, yet another Aussie young gun, lived up to his 29th seeding by breezing past Denis Istomin.
