You like tennis matches outside of the top players, that's a rarity on here
I expect RRH is going to win solely because Dustin is going to error himself out of the match. As you said, his game is average. His hope is that he simply outhits RRH or forces RRH into errors with his power. He also has to serve and return huge. But in a best-of-5, I truly doubt Dustin has any sort of consistency to stay with someone mentally and physically tough as RRH is.
Yeah, the names might not be as impressive (as a Querrey, Verdasco etc) but the matches are generally more competitive...and I like to see a good battle. Nothing worse than paying 2, 3, 4 times more money to get a ticket to a show court and see Murray, Federer, Del Potro etc beat up the little guys.
The ground pass is where it's at.
Like the Phau/Mello match, again, I can't call it with confidence.
You're right about Brown...he will surely hit plenty of errors. Will he hit enough errors?
He'll certainly need a good serving performance to keep his nose in front. From there, it is up to RRH, and I've seen enough of his own serving to know that he is prone to losing rhythm (and his serve isn't even particularly big)...his take back is a little dodgy.
