Cheers for that. Hopefully he can adapt. Mahut isn't a very good returner so James' serve might hold up alright tomorrow regardless.
If you watch how James is serving today it seems he has no problem flattening out his first serve and getting it over 200kmh. Great to see he knows how to switch his play when on a different surface. Even though he is down a set he is more than capable of beating Simon, mainly due to the the way Simon plays.
