But yes, I do think Maria's play against Vika will continue to improve, although like I said I'm not going to pretend I have anything more substantial to base it on than gut instinct. One thing I do think that should be beared in mind is, imo, Maria doesn't get enough credit for her willingness to adapt her game to certain opponents, and her persistence in trying to beat players who are owning her at a time. I mean, apart from Serena, there's NEVER been an opponent in her whole career that Maria hasn't eventually figured out a way to play eventually, even if she first struggles with them for 1 or 2 seasons. Look at her match-up with Li -- admittedly Maria never struggled with Li quite as much as she's struggled with Vika, but still, going from losing 4 matches in a row against Li, to comprehensively figuring her out in 2012, is still a pretty drastic turn of events.
Anyway, even if it turns out Vika ends up having the upper-hand on her in 2013, I'm still very much looking forward to it, and in fact their US Open semifinal was for me the best WTA match of the year, even if it didn't end the way I wanted it to
And I actually have a feeling that, irrespective of who wins the majority of their matches, most of them from now on will be closer to the USO match, rather than the one-sided wins they've mostly been getting over eachother until now.
