I think that's a bit harsh fletch - after all, MLDB may be a better player than Mel, so it might be nothing to do with mental weakness! That said, playing no matches for 6 weeks can't be good for your game mentality. 2 GPs missed...but she takes it!
Well I can't see the match so I may be wrong, but in the first set according to the (admitedly sometime dodgy) stats Mel hit 11 winners and only 2 UE's. If she had kept up that form she would have won quite easily I think.
