New court 'like a garden'
Garbine Muguruza won the first-ever French Open match to be played on the picturesque Court Simonne Mathieu, beating Taylor Townsend in three sets. The 2016 champion was impressed by what she saw.
"It's in a very different place. You don't feel like you are around court. It's like in a garden. It's a different feeling," she said.
From hero to zero
Italian Marco Cecchinato made waves last year in Paris with a shock victory over Novak Djokovic helping him reach the semi-finals as the world number 72. Twelve months on, though, and seeded 16th, he blew a two-set lead to lose 2-6, 6-7 (6/8), 6-4, 6-2, 6-4 against French veteran Nicolas Mahut.
Due to the lost ranking points, Cecchinato will slip from 19th in the world to outside the top 35 at the end of the tournament, probably even losing his seeding for Wimbledon.
Unheralded German lucky loser Oscar Otte will play a dream second-round match against his "idol" Roger Federer, after his win over experienced Tunisian Malek Jaziri more than doubled his prize money for the year.
But he also counts former cricketer Mark Benson, who played one Test for England, as an inspiration.
"I have known him for a long time and have got to know him quite well," Otte told AFP of Benson, who is the father of the man who is soon to marry Otte's sister Luisa.
"I know about his career which was very impressive and I always keep in touch with him."
"I would be surprised if Roger knew my name." - Otte on his illustrious next opponent.
"The reception I got today was crazy, was really nice to see a full stadium for a first round like this. It was a beauty." - Federer was taken aback by the packed Court Philippe Chatrier for his first French Open match since 2015.
"It was a bad day today. I don't want to speak a lot today. Is very, very tough on me after last year. So I think it's bad day today." - Cecchinato delivers a one-answer press conference after his collapse against Mahut.
"The clay season is over now for me. Yeah, I'm happy about that, that I can now looking forward to playing on grass." - Angelique Kerber was ready to put a disappointing clay-court season behind her.
"She's actually one of my idols, and when I was young I was looking for her game, how she's playing."
- Potapova was delighted to play against Kerber, 13 years her senior.
"Very soon. I'm still working on it. It's developing. Construction."
- Stefanos Tsitsipas is giving nothing away about a supposed secret he will soon be sharing on social media.
Four - Years since Federer's last French Open appearance, a 2015 quarter-final loss to Stan Wawrinka.
Six - The number of times Kerber has fallen at the first hurdle in Paris, including in three of the last four years.
60 - Successive first-round wins for Federer at Grand Slam tournaments.
350 million - Euros spent on the renovation of Roland Garros.
