Roger Federer vs Tommy Robredo
Despite being 0-8 against Federer, Tommy Robredo has played Federer quite tough at times on hard courts.
Federer hasn't been particularly sharp yet in the tournament but it's hard to pick Robredo when he's won just two sets in eight matches against him previously.
Robredo will pound the Federer backhand but without a real weapon to consistently hurt him, Federer will take this in straight sets.
Novak Djokovic vs Radek Stepanek
It finally appears that Djokovic is playing well after a few months of very mediocre tennis.
Djokovic holds a 3-1 record against Stepanek and they played a five-set marathon two years ago at the US Open, which went to a fifth set tiebreaker.
I don't think the match will be that close today but I think Stepanek will push this to a fourth set and make Djokovic earn this win.
Robin Soderling vs Nikolay Davydenko
By far, this is the most interesting of the four matches today.
Soderling owns a 4-2 career record against Davydenko but is only 1-2 against him on hard courts.
Soderling has become a household name since beating Rafael Nadal at the French and losing to Roger Federer in the finals.
Despite his heavy ground strokes, I'm leaning towards Davydenko to win a very close five-set match.
Fernando Verdasco vs John Isner
Isner is coming off the win of this career and will have the crowd behind him as he plays the very talented lefty from Spain.
For Isner to have any chance, he's going to have serve big and keep the points short.
Verdasco is a power player with a tremendous forehand. Expect Verdasco to use his power and topspin to move Isner around the court.
If Isner gets the lead in this match, he has a chance.
I don't think he will and I think Verdasco rolls in straight sets.
