I have to agree the calls have been REALLY REALLY bad this week. There are some very idiotic linesmen out there.
I noticed this in the Cornet-Jankovicmatch as well. There was a VERY bad call at *4-3 for Jankovic in the third set. A point that was crucial for Cornet's confidence. Anyone could see that ball was in.
I really hope we won't be getting these bad calls in the final.
