Wow, what a tight match! Congrats to Guillermo. He's been so impressive this year on all the surfaces. I feel bad for Haas, it looked like he was in full control in the 3rd. Losing his serve at 4:3 and 40:0 turned out very costly for him. But overall the match was very tight in the tiebreak as well, could have gone in either's way.
Go Novak tonight!
