Are you watching the same matchs as I am? Brown is playing all or nothing tennis and is making more shots than missing. Ferrer is usless at this king of game as he dosen't have a strong serve to take the initiative away from Brown.
Ferrer has never needed a great serve to counter great servers. He normally has a great return to counter great serves. But from what I've seen, he's playing poorly today (I did see some very unusual UEs, at the net for instance).
Anyway, WTF is happening now? Cleaning the court?
