i think maria lost because she isn't playing quite as consistently now (might be that she's still not fully back from injury but she's a bit inconsistent). she is also having mental problems atm. RG 5-1 up in the 3rd set against safina, she really should have won that one and it's continued through wimbledon. she also doesn't play as well on the big points anymore imo at least she hasn't this wimbledon, that's why the pennetta match was tougher than expected, that's why dementieva was able to come back into the match because although dementieva stepped it up a bit sharapova was still playing pretty well until it came to the tight situations where she missed a few shots she shouldn't have.
