Roger Federer began grand slam life as a father of four with a supremely comfortable victory over Lukas Lacko in the first round of the French Open. The 2009 champion arrived in Paris this week with his expanded family in tow following the birth of his second set of twins, Lenny and Leo, nearly three weeks ago. His four-year-old daughters, Charlene and Myla, were in his box on Court Philippe Chatrier for the start of his 6-2 6-4 6-2 win against Slovakian Lacko.
