Now I remember, dreadful weather disrupted play the year he got to the final
BBH, you of course are correct.
In 2008 after he won in Cincinnati and reached the USO final, he lost to Federer, having defeated Nadal in the semi-final. Unfortunately, owing to the bad weather he had to play his SF over two days. Therefore, by the time he was pitted against Fed, he was exhausted, his opponent having enjoyed almost two days rest.
The danger is this year there could be a replication. Djokovic gets to the final with plenty of rest and Andy has to beat Nadal over two days.
It won't happen! The situation will be reversed! Andy will get to the final refreshed and Novak will have to play his SF over two days.
As Andy is the current Cincinnati champion, repeating 2008, I can now see AM as the USO champion! Thereafter, with the monkey off his back, the world and no1 awaits!
