Unplayable...Unbeatable?

Wow. How good is Roger Federer.

The world number one put on a tennis masterclass as he defeated a helpless Lleyton Hewitt in straight sets to advance to this year's Australian Open quarterfinals. The Swiss Maestro was in superb form against Australia's best player, highlighted by powerful and almost unplayable forehand strokes. Every time Hewitt tried to lift his game and gather some kind of momentum, Federer responded with authority. As only he can.

There was very little anyone could have done to stop the world's best. Hewitt was able to land a high percentage of first serves in to keep the pressure on Federer, but it was still to no avail. Every shot that Federer hit turned to gold as he embarrassed the 22nd seed and silenced a packed Rod Laver Arena.

Federer's domination has once again raised that question. Can anyone beat him?

Nikolay Davydenko will be doing his utmost to defy that question. After defeating Fernando Verdasco in a tight five set match, the inform sixth seed will face a red hot Federer. In their last two encounters, Davydenko has won both times. However, Davydenko looked a little unconvincing against Verdasco after being up two sets to love, while Federer was at the other end of the scale. It'll be a great match, so make sure you tune in and watch.

I've just finished watching another five set epic, this time between Jo-Wilfred Tsonga and Nicholas Almargo, with Tsonga winning 9-7 in the final set. It took the big Frenchman just under four hours to eliminate Almargo, who fought right to the very end. The match was enthralling, and it was well assisted by some hilarious commentary from a former French player. Tsonga has now set up a replay of the 2008 final against Novak Djokovic. The Serbian has had a great run and will have the fresh legs. Djokovic will be tough to beat.

As for the women, Serena Williams showed why she's the best by thrashing Australia's Sam Stosur in straight sets. Her sister Venus got off to a slow start but eventually recovered to win in three sets against Francesca Schiavone. The biggest upset came when China's Na Li eliminated Caroline Wozniacki in straight sets, a massive surprise considering Wozniacki had been playing so well throughout tournament.

BTW, look out for a great match tomorrow between Andy Murray and Rafael Nadal. Park yourselves on the couch because it could be a long one!

BTW, the two teams for the 2010 NFL Superbowl have been decided with the Indianopolous Colts and New Orleans Saints defeating the New York Jets and the Minnesota Vikings. Led by Quarterback Peyton Manning, the Colts' star studded offense outplayed the Jets' defense as the Jets struggled to run the ball on offense for the first time in a while. In the other game, Garrett Hartley successfully completed a field goal attempt in overtime, after Minnesota's Quarterback threw an interception, to take New Orleans into their first ever Superbowl.
