I don't agree that the Match against Isner was scary, for me it showed how well Andy was serving,defending as well being offensive. Isner was playing the best tennis he has ever played, serving down first and second bombs and Andy beat him. As to Dimitrov loss there was something wrong and Andy said he should have won the Tsonga match, but even in that match he was playing really good tennis. Fed lost in straight sets to Tsonga.
Of course there were a lot of positives to the fight from Andy in the Isner match, but having to save 2 match points gets me nervous every time. I agree with your thoughts on the Tsonga match, he did play some great tennis, but its never easy to forget a 3-0 lead blown to go on to lose in the final set for a fan. Credit to Tsonga too, great week for him. Maybe Andy can have a similar week. I need to find my confidence and faith in him again, and there is no better time to do so than now.
