Serena Williams laid the ghost of Roland Garros 2012 in emphatic style by powering through this year’s opening match against Anna Tatishvili.The world number one needed just 51 minutes to beat the Georgian, ranked 83rd, 6-0 6-1 on an autumnal Court Philippe Chatrier.She was followed onto the stadium court by Roger Federer, who swept aside Spanish Grand Slam debutant Pablo Carreno-Busta 6-2 6-2 6-3.The 21-year-old qualifier went into the match on the back of seven titles this year on the satellite ITF Tour, five of them on clay, but he found the 17-time Grand Slam champion an altogether different test.Federer raced into a 4-0 lead and was broken just once as he began his bid for a second French Open title with victory in one hour and 20 minutes.Williams suffered her only first-round defeat at a Grand Slam when she lost to world number 111 Virginie Razzano 12 months ago and was in no mood to suffer a repeat performance.The American, 31, has admitted that loss was a huge blow which sparked a stunning run of form as she won Wimbledon, the Olympics, the US Open and this year has racked up a career-best winning run of 25 matches.Tatishvili became the latest victim in the most brutal fashion, taking 33 minutes to get on the scoreboard as Williams dominated in all areas.A screaming backhand winner gave Williams an eighth straight game and the fist pump that followed showed just how much winning a second French Open title, 11 years after her first test, is motivating her.Tatishvili, who has won just two matches in 2013, did at least slow the top seed’s progress in the second set but Williams completed the job well short of the hour mark.Williams next plays 19-year-old Caroline Garcia of France, described by Andy Murray as a future world number one after he watched her take a set off Maria Sharapova at the 2011 French Open.
