The amount of intelligence Tommy put in last 2 matches is simply brilliant. He outsmarted both Novak and Simon by outplaying them, never letting them in their rythm. He absolutely controlled every single shot.
I dare to say this game could very well resemble the peak days of Tommy, as his game is vastly different then the Haas version from 09' success. Back in 2009 he adopted more S&V style, considering he only returned from another big injury, avoiding huge rallies, basically to shorten points.
2013 Haas is back to his game. All around game that he has been always known for. Such variety of shots and shot selection is just magnificent. Volleys are still there, with some amazing top spin lobs, chip and charges and amazing slices.
One of the best improvements over the last years, Tommy improved mentally, keeping more focus, never loosing patience.
There was a time vs Djokovic where Novak got break back in 2nd, I really thought epic choke is coming again after having 6-2 2-0 and few BP for *3-0.
That match was huge self confidence boost, although I do believe he has all the motivation he needs right from the stands, with his baby girl finally watching him play
