Not sure why Federer is getting some hate here
Federer played pretty well bearing in mind with his opponent. He served well which is important if he wants to succeed in the latter stages of the tournament. He shouldn't be falling to the trap that Federer is back and guaranteed on his chances for the title just like the results he was getting in R1-3 at FO but now that Nadal is out, he should get some relief.
(Maybe I should get involved with the MTF way and living with the connotations and lingo people use and overall show the obnoxious behavour towards people like some others so I can join the fun around here.
