Roger Federer marked his return to Roland Garros after a four-year absence with a straight sets win over Italy’s Lorenzo Sonego on Sunday.
Federer, a 20-time major winner, hadn’t played the tournament since 2015 when he reached the quarterfinals.
However, on Sunday, it was as if the 37-year-old had never been away as he swept to a 6-2, 6-4, 6-4 victory in one hour 41 minutes on a packed, rebuilt Court Philippe Chatrier.
It was his 60th successive first round win at a Grand Slam and he said he admitted he “felt on edge.”
“I felt on edge at the start, my heart was beating crazily,” said Federer, who hailed the new-look stadium which has been 90% rebuilt in readiness for the installation of a retractable roof for 2020.
“I felt great playing on this court. It looks very attractive, so congratulations to everyone involved.
“Hopefully I can play here again for my next match.”
That match will be against German lucky loser Oscar Otte who won just his second match in eight years on the tour by seeing off Malek Jaziri of Tunisia 6-3, 6-1, 4-6, 6-0.
“I would be surprised if Roger knew my name,” said Otte, the world number 145.
German fifth seed and reigning Wimbledon champion Angelique Kerber saw her hopes of a career Grand Slam ended by Russian teenager Anastasia Potapova.
Kerber slumped to a 6-4, 6-2 defeat to 18-year-old Potapova who was making her French Open debut.
The 31-year-old has now lost six times in the French Open first round.
Greek sixth seed Stefanos Tsitsipas, who stunned Federer on his way to the Australian Open semifinals and beat 11-time Roland Garros champion Rafael Nadal in Madrid, also made the second round.
The 20-year-old sixth seed brushed aside Germany’s Maximilian Marterer 6-2, 6-2, 7-6 (7/4).
