Can gonzalez take a set?
For people interested in a 3-1 outcome my opinion is that Gonzalez to win the first set is a better option. Firstly it pays better.
Then there's the fact that in his last 2 matches he destroyed Nadal and Haas in the first sets. Both Nadal and Haas got better at trying to deal with Gonzalez as the matches went on but could find no answer to the explosive power in their first sets. If Federer is to drop a set, it's most likely he'll do it in the very first one, assuming he's cautious or slow to find an answer to the (new?) Gonzalez game.
On the minus side, both sets Gonzalez won have been the second ones vs Fed, Fed looked extraterrestial against Roddick, and they've played so many times perhaps Federer knows Gonzalez's game too well.
On the plus side Gonzalez has looked extraterrestial too, and Baghdatis managed to take the first set last year.
