So far in this tournament he's beaten each of his opponents, most recently Feliciano Lopez, in straight sets.
He's playing some of his best tennis right now and is a real threat to win the entire tournament.
In his quarterfinal match, the second-ranked Nadal will take on No. 7 Tomas Berdych, a player he's had a lot of success against historically.
Against Berdych, Nadal is 10-3 and has a nine-match winning streak. In the 2010 Wimbledon finals, Nadal beat Berdych in straight sets, 6-3, 7-5, 6-4.
Nadal has been a beast in Australia so far, removing any doubts about whether or not he was healthy after battling knee problems.
When he's at the top of his game, Nadal's behind-the-baseline play is second to none. He's a talented defender who will force Berdych into several mistakes.
Berdych is already at a disadvantage in this match in terms of fatigue. While Nadal has been breezing through his opponents, Berdych has struggled.
In his last match, against No. 10 Nicolas Almagro, Berdych needed five sets to advance. He's needed extra sets to beat two of his opponents thus far.
And, after the match, he refused to shake Almagro's hand. That won't bode well in terms of karma.
The Aussie fans booed Berdych relentlessly after the hand shake snub. Some of those boos will likely surface at various points during his match against Nadal.
When you're playing a guy as skillful as Nadal, you need every advantage you can get. Right now, Berdych has zero advantages.
If Nadal doesn't continue his dominance of Berdych, I'll be surprised. Look for another straight set win for the graceful Spaniard.
That would move his winning streak against the Czech to 10, a very impressive feat.
