First thing's first, a lot of credit has to go to Roddick. His gameplan was (a) superb, and (b) perfectly executed. He stuck to his guns throughout.
On top of that, that has to be one of his best ever serving performances to boot. 80% at 130mph + AND very good placement is about as good as it gets.
On the other hand, Murray will look at this match as a major missed opportunity. Unlike Roddick, his serving was mediocre. Specifically, his 1st serve was very hit and miss today. When it worked, it was awesome. When it didn't, he was up against it. He needs to establish a 1st delivery that is a solid 65% throughout. In the first and third sets, the games where he was broken he hardly put a first serve in. THAT is when he will be punished more.
People are going to identify Murray's 2nd serve as a weakness. Bottom line is that it is. When he serves 70% on the 1st serve, it's a reasonable delivery to back it up with. When he serves around 50%, THIS is when he gets picked off with it.
I felt that today he didn't really adjust his tactics to compensate Roddick's plan. Roddick had no intention of attacking the 1st serve, and Murray is at least a 60/40 favourite in most baseline rallies. Murray should have concerned himself with taking a fraction off the 1st serve and getting into play. For a player who is usually quite astute tactically, I'm surprised he didn't read this play.
The other thing I hope Murray learns from this match is that there are some players you have to take the game to. Stroke for stroke, Murray is a superior player to Roddick (and most others), but he never asserted that today. The Murray against Ferrero never turned up here.
Last winter, Murray really stepped his fitness up an extra notch. This close-season coming, he needs to develop his aggressive game and work on putting together a 2nd serve that has more variety. I'm not sure he necessarily needs more pace, but he needs to be confident that he can slice wide (deuce)/ down the T (ad) and kick down the T (deuce)/ kick wide (ad) consistently. Hitting the corners will help him no-end.
When all said and done, he lost to a better man on the day. Best of luck to Roddick in the final. If he can bring that sort of serving performance back to Centre Court on Sunday, he has an outside chance.
