Re: Was Rosol def. Nadal the biggest upset in tennis history?
Not even close.. Soderling defeating Rafa at the French was a much bigger upset, and even then, I wouldn't consider that the biggest upset in men's tennis, although it is certainly up there. Rosol beating Rafa was not entirely surprising, at least for, even soon after the match. Yes, it was still rather unbelievable that Rosol pulled it off, however, remember that Rafa was down so many times at Wimbledon throughout the years and he has narrowly escape each time, a couple times due to some luck on his side. Kendrick was 2 points away from winning their match in 2006, Soderling had a break? or had break points in the 5th set in 2007, Youzhny was up 2 sets to love in 2007, Federer had his chances in the 5th set in 2008, and Petzschner/Haase also had their chances to win their matches against Rafa in 2010. So I'm not sure how a player, as in Rosol, who was able to take that one extra step all those players before him couldn't is considered a huge upset.
Chang beating Lendl at the French Open is arguably one of the biggest upsets. Chang obviously very young, far less experienced and Lendl was a multi slam winner both overall and at Roland Garros.
Federer / Haas / Safin / Gaudio / Kuerten / Youzhny / Nadal / Gonzalez / Ljubicic / Hewitt / Soderling / Wawrinka / Coria / Nalbandian / Kohlschreiber
