Rather than glass half empty i see it as glass half full. It takes greater courage and mental strength to change a particular course of action that affects the body at its psychological and physiological levels, than it does to succumb to these inner pressures.When you say Andy needs to toughen up, doing what he did in that passage of play, lost his focus, allowed his opponent back in then promptly broke his opponent and then attempt to serve out the match again, only this time successfully, took an enormous amount of mental strength. Andy is mentally tough already. Andy recognized the danger he was in and took the correct course (keeping his nerves at bay, and refocusing his mind - staying in the here and now). While i understand why you say what you say Joe, i just don't agree with it. Sometimes things on the surface don't always reflect whats really going on inside.
That really is the bottom line PT that would-be-analysts like myself should remember.
It's just that, as fans we find it hard to see him nearly lose or actually lose a match because of this phenomenon
when he clearly should win and often with a good margin. Other players suffer from this too, look at Del Potro yesterday, what a shame that was.
Andy is a particularly sensitive young man (IMO) who is still developing in all respects. We'll see him tackle these situations better as his self belief improves.
