The quarterfinals for the boys 18s in Denver are set. Of the guys I've seen, I find it difficult to imagine Jack Sock losing a set, much less a match. The best news is the most whiney , most annoying player ever (W McCoy) lost in the opening round. There is something about that kid that makes it easy to despise him. Tomorrow, Jack Sock takes on Asika Isoh, who has looked pretty solid thus far. Chris Cooprider, who evidently won his 2nd round after a controversial overrule on matchpoint extended the match (I didn't see it but heard from others), takes on Patrick Kawka, Augie Bloom faces Casey MacMasters and Eric Sock plays Alex Lineberry. The latter survived a bagel opening set to win in an exciting round of 16 match. If I had to guess the finalists, I'd say J Sock vs MacMasters, though the elder Sock has been impressive.
