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 while Marin Cilic was stunned by Bulgarian Grigor Dimitrov in the second 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.
With perfect Swiss timing he broke serve once in each set in the 10th game of the first, the eighth game of the second and the ninth game of the third to subdue the world number 144.
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.
Third seed Federer, whose only French Open title came 10 years ago, has won his first six sets and with a favourable draw he looks in the form to mount another challenge.
Next up for the 20-times Grand Slam champion is Norway’s 63rd-ranked Casper Ruud.
In the other men’s singles, Dimitrov twice came from a set behind to outlast 11th seed Cilic in a heavyweight second-round clash at the French Open on Wednesday.
The former world number three, unseeded this year at Roland Garros after falling to 46th in the rankings, produced a gutsy display laced with pure shot-making to win 6-7 6-4 4-6 7-6 6-3.
Dimitrov moved 5-2 ahead in the decider with two breaks, but Cilic was not going out without a fight and saved a match point with a booming forehand as he repaired some of the damage.
Cilic netted a backhand in the next game, however, to hand Dimitrov a notable victory.
Dimitrov has never been past the third round at Roland Garros and if he is to extend his stay beyond that this year, he will have to do it the hard way.
His next opponent is 2015 champion Stan Wawrinka.
