Well it all depends on what happens with Serena, Vika, if Petra can pull it together or Li. Serena, Vika and Li haven't had the best of luck with their bodies, and Petra well the only thing she is consistent at is mental madness. I expect for now for Serena to continue to be a thorn in Maria's side. Vika is 50-50 versus Maria in my eye those encounters can go either way. Petra can be a formidable foe once she gets her crap together. Li gave Maria a beat down in Australia after Maria was looking to cruise her way back into the final this year. I think Maria given the current crop of foes can realistically expect a 2-3 more slam haul maybe more if something happens that puts all 4 of the above ladies out of commission for a while. A few things I think that work against Maria in reaching double digits is she has never won multiple slams in a year even when her serve didn't have the problems it does now (it has improved but no where near the weapon it was before the shoulder surgery), she has never defended any of her slams and all of her slam wins have a lengthy span between one another Wimbledon 2004, US Open 2006, Australian Open 2008 and French Open 2012. It is a pretty telling when the biggest thorn in your side, Serena Williams is out of shape/injured from 2005-2007 and late 2010-mid 2011, and you aren't adding to your slam haul from that time frame.
