All good points, and I am not saying he is in great form but he still managed to win. He played great 1st set against nadal on clay and nadal his couple spectacular shots in tb to take that set. I knew Novak was going to beat him in London.. On the other hand, Nadal can lose to couple players on hard court in New York too. Tsitsipas just played that week out of his mind..Novak will regroup now, in NY he plays every other day, and he has all the confidence in the world.. We all know how couple years went when he had all the confidence.. Will be great tourney for sure..
