By Martyn Herman PARIS (Reuters) – Roger Federer avoided any more security scares to move safely into the third round of the French Open on Wednesday but danger lurks ahead for the Swiss, namely in the shape of Japanese firebrand Kei Nishikori. The perils of Roland Garros were in evidence in the women’s draw too as last year’s runner-up Simona Halep, the third seed, bowed out 7-5 6-1 to Croatia’s Mirjana Lucic-Baroni to become the biggest casualty so far. The 33-year-old Lucic-Baroni, who made her French Open debut in 1999 as a 17-year-old but took a break from tennis before returning, also beat Halep in last year’s U.S. Open.
