Roger Federer may be 31, but it doesn't exclude him from being the favorite at the 2013 Australian Open.
Andre Agassi won an Australian Open at age 32 in 2003, the last time someone 31 or over has won the tournament.
Federer is still his dominant self and just because he's 31, it doesn't mean he can't win.
So far in this tournament, he's done quite well.
Federer won his first match over Benoit Paire 6-2, 6-4, 6-1.
He won his second match over Nikolay Davydenko 6-3, 6-4, 6-4.
Federer then won his third match over Australian Bernard Tomic 6-4, 7-6, 6-1.
His latest match was a victory over Milos Raonic, by a score of 6-4, 7-6, 6-2.
Federer will take on seventh-ranked Jo-Wilfried Tsonga next for a place in the semifinals.
He may not have the athleticism of his younger counterparts, but no one has the experience or smarts that Federer does. He doesn't have to beat you with his legs anymore—he beats you with his head.
Federer is still the best out there and while the road to a title is certainly long, it's not out of the question. He's shown that he hasn't lost too much as he ages, and what he has lost, he's learned to compensate for.
Yes, tennis is about speed and getting to shots, but it's also about making the right shots and knowing how to set opponents up and when to put them away. Federer is the master of this skill.
Besides, he can still win. He won Wimbledon at age 30, and nothing drastic has changed since then.
His age won't stop him. If anything, it could be an advantage. Look for Federer to enjoy life as the favorite and come out victorious at the 2013 Australian Open.
