PARIS: Even during a clinically efficient win, Roger Federer still produced enough masterstrokes to have the French Open crowd purring as he moved past German qualifier Oscar Otte into the third round on Wednesday. The 37-year-old, welcomed back to Roland Garros with open arms after missing the last three editions, was kept on his toes throughout the Court Philippe Chatrier contest, but raised his game when needed to prevail 6-4 6-3 6-4. Just for good measure Federer finished the one-hour 36 minute match off with a signature flourish on the Parisian clay, a glorious drop volley played with casual ease. Next up for the 20-times Grand Slam champion is Norway’s 63rd-ranked Casper Ruud.
