I was only able to watch from 5-4 in the second, but from what I saw Federer was playing really well. There were a lot of great rallies from both players. With Djokovic, Federer, Nadal and now Wawrinka it goes to show you that we often deem players done too early. I admit to being guilty about Wawrinka and at some point Nadal. I think this was the best Federer has played since Shanghai and Basel last year. He has had some good spurts at Wimbledon and Aussie Open this year, but not consistently. I actually feel that this US Open is close to being more open than last years. Who knows what Federer will show up, Djokovic has looked very shaky since Wimbledon and Nadal has never defended a title off clay. However, I feel that Nadal's form might be the best. Strangely in a reverse of the usual ough I feel that Federer will beat him if they play. The problem is that they might not play. I hope Federer can even the series with Djokovic here at 23-23. There last match was that hideous Aussie Open 2016 semifinal. Those first two sets might have been the best tennis I have ever seen. He still has a way to go to get back to it and these courts are hopefully too fast for him.
