Self-destruction from Jo.
Yes, he was robbed of that line call and I agree completely that the umpire should have overruled - it was right under his nose. But, Jo has got to learn to move on. Everyone has suffered horrendous decisions from officials, but the players with stronger mental fortitude find a way to put it behind them and do their utmost to win. Instead, he was practically throwing his toys out of the pram after that call. I didn't mind the racquet-breaking - this produced positive energizing response from him, albeit short-lived - but I was disappointed with the negative attitude, bordering on petulance.
Those mis-firing forehands, insecurity about his backhand (which is not as bad as he thinks) were signs of fatigue - both mentally and physically. Maybe he would have gone to lose anyway given how well Soderling was playing but next time, I'd like him to take a look at the bigger picture (London qualification) and trust in himself and his amazing abilities instead of blaming external factors. And if he loses, having tried his best, then fair enough.
Anyway, I wish him good rest and recovery and look forward to seeing him re-energized once more.
