[Senator Clay Davis]

Kyrgios had a serving day for the ages, 25 aces against is the most Novak has ever allowed in a three set match, and of course the match didn't even go three sets. He will likely follow it up with a totally disinterested display in the semis, and we'll still be wondering if he ever puts it together. Incredible talent, without a doubt. He's also, along with Lleyton Hewitt, the only player ever to beat Rafa, Roger and Novak in his first match against them, though Kyrgios obviously got the better versions of those players than Hewitt did.
