The Swiss world No 3 hardly breaks sweat in his 6-3, 6-0, 6-2 second-round French Open victory against wild card Maxime Teixeira.
A walk in the park for Roger Federer
The World No 3 Federer thrashed the French wild card Maxime Teixeira 6-3, 6-0, 6-2 in an 84-minute morning warm-up as dozens of panama hats bloomed in the Court Suzanne Lenglen stands.
Federer, who has not won a major since the 2010 Australian Open, misfired a few routine forehands in the opening set before he stepping up a gear to flatten the world No 181 Teixeira.
The 16-time major champion who will next face the Serbian Janko Tipsarevic, offered some words of consolation to his unheralded opponent.
"It is so hard to play on a big court when you're not used to it. I think Max did a good match. He fought well," the Swiss said courtside.
The 22-year-old Teixeira, who had never played a match on the main Tour before this year's French Open, said: "It's an incredible experience. Playing against Roger is something I will never forget. I did what I could."
Little-known Romanian Simona Halep will probably like to forget her Court One outing on a sunny Parisian morning against last year's runner-up Stosur.
Stosur looked like she would be handing Halep the dreaded 'double bagel' for breakfast but in the end had to settle for a 6-0, 6-2 win in 66 minutes.
On children's day at Roland Garros, the No 8 seed Stosur was in no mood to fool around as her pace and kicked serve proved too much to handle for the world No 67, who bowed out when she mis-hit a cross court forehand.
Caroline Wozniacki, the world No 1, was coasting towards a routine win but her second-round opponent, Canada's Aleksandra Wozniak, trapped her into a lobbing contest and set up three set points in the second set.
The Dane who has yet to claim a major title, survived the test thanks to her powerful forehand and won 6-3, 7-6.
The heat and a plucky opponent initially left the 17th seed Julia Goerges frazzled as she fell a set and 3-1 behind.
But the in-form German, who won the Stuttgart tournament and reached the last four in Madrid during the past few weeks, relied on her survival instincts to beat the Czech Lucie Safarova 2-6, 7-5, 6-2.
Goerges, however, did not let the win go to her head. Asked who she would pick as the tournament favourite, she quipped: "For sure not me."
Later today, Novak Djokovic will be looking for his 39th successive victory this year and aiming to prove to stuttering rival Rafael Nadal that he is ready to steal his crown when he meets Victor Hanescu in the second-round
Top seed Nadal, bidding for a sixth Roland Garros title in seven years, endured his first five-set match on the Paris clay last night when he battled back to beat the US player John Isner.
World No 2 Djokovic, who beaten Nadal four times this year including twice in clay court finals, had no such problems in Monday's demolition of Thiemo de Bakker.
