Agreed, Maria plays pretty defensive against Serena, even when Serena gives her short weak balls.. She's just really troubled bu her mentally, I don't why she can't get over that block
I believe that Serena played a big role in this mental block, Maria had chances to beat Serena many times and the latter always found a way to win yes Maria should have won in OZ semis, she should have won in Charleston, she should have at least take the first set in Wimbledon 2010. Mentally I think Serena just destroyed her, it's hard to admit but it's true.
Serena has won matches that hurt Maria more than she want to admit, not to mention the several matches she lost very badly.
The second part is that tennis wise, Maria is simply far from 2006 or 2008, since Hog came Maria's tennis became a lot less riskier, less precise she uses a lot of topspin she engaged herself in many rallies and against someone like Serena it's just not possible to play like that, she exposed her movement way too much she has improved on this area but still against such a big hitter like Serena it's not gonna cut it.
Her game is working against pretty much everyone and she could have won that title if it wasn't for Serena, just like YEC too but Serena is there and Maria seriously needs to think of a different approach to at least take a set off of Serena.
I need Maria to play Serena in Rome or FO just to convince myself that Maria's tennis on red clay can do sth more but if she happens to lose 3 and 3 as usual she can seriously think about changing coach or I don't know but sth new needs to be done.
