After winning the Aussie open Djokivic has lost to a qualifier in a Sony Erricsson open. Top players losing to relatively unknown players is becoming a bit of a trend this year and could make for some interesting results. Already this year both Andy Murray, Roger Federer and Nadal have lost matches they should have easily won.
How will the top players perform for the rest of the year who knows, but will any player other than Federer, Nadal or Djokovic win a Grand Slam? Probably not, the only player that could push them is going to be Andy Murray.
If anyone feels different to this or just wants to give their opinion comment away.
