To me, usually the last few years, when Federer lost those crazy sets and matches against journeyman, it was often more the forehand malfunctioning, not being reliable and all, then his backhand. He seems to have solved this. His forehand looks great again, and he rarely loses sets he shouldnt at this moment. I think I haven't seen a match with Fed spraying errors on his forehand all day long since last summer? How does he do this? Did he make a change? Is he more focused? Does he have mroe confidence?
