Down to the final four at the Aussie Open and here is a little preview of the matchups. Federer/Djokovic is going to be a blockbuster, and thus far Federer has a 5-1 career head-to-head versus the younger Serb. I'd give a 50/50 chance here to either player. Djokovic has looked so dominant this past week and a half without losing a set. Federer came so close to being bounced in the 3rd round, but has looked pretty strong himself since then. A five setter should would be a treat from these two.

Nadal/Tsonga is more of a mystery, simply because nobody expected Tsonga to make it this far. Nadal leads their career head-to-hear 1-0, and that lone victory came at the US Open last August. The way Tsonga has been playing it's hard to really predict the outcome of this matchup, although Nadal goes in as the favourite. Nerves may get to Tsonga, never having been this far in a major before.

I'll post again before the finals.
