The hottest storylines this week in men's tennis are upset, upset, upset.
Joao Sousa upended Julien Benneteau to snatch his first title. Sousa also beat David Ferrer. Milos Raonic crushed Tomas Berdych.
Upset, upset, upset.
Perhaps equally upsetting to fans of the top players is the continued absence of former world No. 1 Roger Federer. The Swiss superstar has taken off a significant amount of time since the U.S. Open which had ended disappointingly for him. Now he finds himself struggling just to qualify for the year-end World Tour Finals.
Finally, as most attention is drawn towards the tour's end, Rafael Nadal shows there is more to fight for than just one tournament. He looks to take over the top spot in the rankings after the China Open.
The week ahead should be full of intrigue and lots of excitement.
