The Australian Open is coming towards the end of its first week, and there are a few underdogs to look out for. These guys are the underdogs most likely to come away with a shock result in the first of the fourth-round matches on Day Seven.
There have been some great underdog stories and a few big upsets already at the Australian Open. Keep an eye out for these guys to provide a few more.
If you love a good underdog story, then these players are definitely the ones to watch when they take the court.
Feliciano Lopez faces compatriot Rafael Nadal on the Rod Laver Arena early on day seven. The two Spanish players will be facing off for the 11th time this evening, and it hasn't always gone Nadal's way.
Nadal has won eight times in their previous two meetings compared to Lopez's two victories. That first victory came back in 2003. The second, though, was as recent as 2010.
Nadal will be a huge favourite for the match, and it is difficult to see any other result, but Lopez is still one to watch. He could just make this a very awkward tie for Nadal.
Bernard Tomic against Roger Federer is the tie the Australian public have been waiting for.
Youngster Tomic is the up-and-coming star of tennis, and what better place to test yourself against a true legend than at home.
The big night match on Rod Laver Arena will see a ferociously noisy sellout crowd urging Tomic towards a shock victory.
It won't happen: Federer is too fresh, and too good, but Tomic is certainly one to watch.
Spaniard Nicolas Almagro will be the outsider when he faces Tomas Berdych in the fourth round.
Suprisingly, these two have only met six times in their respective careers. Less surprising is that Berdych has the upper hand, winning four times to Almagro's two.
Almagro seemed to struggle in his two opening matches, but has now hit form, and eased his way past Stanislas Wawrinka.
Berdych has yet to be tested in the Australian Open and will need to step up his game to beat Almagro.
Maybe the momentum Almagro has will see him through, maybe it won't. But this is one match, and one underdog you need to watch.
