Re: MADRID 2013 Mission: Snatch That #500!!!
Maria feels pressure because she is stubborn. In her head she still clings to the belief that she should be beating Serena, that it's on her racket so the H2H frustrates her. And when that doesn't happen in matches she get's even more frustrated. The other player's who took it to Serena do so because they accept Serena is better and hence feel no pressure, Maria doesn't and while it leads to frustrating matches it is admirable in a sense I guess (some might say delusion, yeah maybe it is but still admirable).
