Masters Cup is under way!

The Shanghai ATP Masters Cup is under way and already we have witnessed the first couple of upsets.

Roger Federer was handed a beating by Fernando Gonzalez, who took the game in 3 sets. This was of course surprising, since Roger was said to be in the "easier" of the two groups. Another player who off to a rough start was Novak Djokovic who was beat easily by David Ferrer in straight sets.

The action will continue tomorrow with an intense battle between Rafael Nadal and his compatriot and friend, David Ferrer. With a win, Ferrer can qualify to the next stage of the tournament. Nadal meanwhile is looking to bounce back from a poor game in his match with the young frenchman Richard Gasquet.

Roger Federer (Switzerland)
Fernando Gonzalez (Chile)
Nikolay Davydenko (Russia)
