Re: Who will be able to defend her slam title in 2013?
If only one of them can do it, it's definitely Serena at Wimbledon. Due to her serve she can play mediocre in every other department and still cruise past most of the tour on grass, only the real top players and a truly inspired opponent can make her raise her game or defeat her there. Pretty large gap, then the alleged winner of RG, as the ladies who can challenge that player have clay as their worst surface and will likely be taken out before meeting them. Vika's AO and God's USO are both doable, but not as NID/highly likely as the first two mentioned.
