Second half of the women's draw is a bear. In the top half, both Muguruza and Halep have very decent draws. Halep on grass is not ideal, but she is so technically sound that it is dangerous to disregard her chances. Still, I like Muguruza to repeat a lot, especially with Kvitova now questionable because of a hamstring injury.
On the men's side, Federer has to be the favourite because he has a sweet draw up to the semis and because he is Roger. I agree with Tuggy that if there is going to be a fly in the ointment this year, it will likely be Cilic. My dark horse candidate: Kyrgios. I might put a quid or three on Nole just for the hell of it, given the 11/2 odds.
Interesting factoid: John Isner, who one would assume should do well on grass, has never gotten beyond the third round at Wimbledon in nine attempts. Height is not necessarily an advantage on a surface that skids.
