Roger Federer reveals how different the conditions can be between day and night on clay

Photo/AFP Roger Federer has insisted he is 100 per cent fit after coming through his opening match at the French Open. The Swiss beat Lorenzo Sonego 6-2 6-4 6-4. The Swiss will next play Oscar Otte in the French Open on Wednesday. Ahead of the match, he has revealed how different the conditions can be between day and night on clay. "On a sunny day, it can definitely play faster than in a night session on hard courts, you know, when you're talking medium, slow, or slow. Because the bad bounces, you know, on clay, that helps sometimes for the serve and volley, the footing is tougher to change direction quickly," He said. "So all these things can help the case to serve and volley. Madrid? I don't think the balls played particularly different, in my opinion, between Madrid, Rome, and then here. Of course, I still have this dream for all the players that we wouldn't have to change balls, you know, but, okay, it is what it is.” Source-TennisWorldUSA
