I think thats smart by Federer. He should focus on the slams to see if he can rack up number 18 (most likely at wimbledon)
Yesterday was such a great day for me in terms of tennis, i'm still buzzing. Nishikori winning his 2nd 500 title, and proving that he is legit. If you want an example of injuries haulting a players progress, look at Nishikori. And Tsonga has more top 10 wins this year so far than the whole of last year. Great win for him considering he was getting outplayed. Finding ways to win when the opponent is better than you on the day is always good. Jo wasn't great in this tournament, but he didn't need to be.
3 of my favourites have won titles in 2013. Shvedova is slacking, so come on Slava and win a title this year!!
