He knows he blew possibly the best chance he is going to get & I think it rattled him way too much. A lot of times it takes Ernests a little while before he gains momentum in a match, however it's harder to recover from that with the top guys. From what I heard, Novak is undefeated so far this year. He has unbelievable confidence right now.
Let's hope we can have a more competitive second set.
