Fed went to the net 41 times against JW and won 34 points. About 84%.
Everybody said, it won't work much against Murray and he can pass Fed easily.
Fed went to the net 66 times against murray and won 75% of those attempts.
So, clearly his net game is clicking. His service game is rock solid. His return
game is improving.
On the other hand Rafa did not play well against Kei even though he won in
three sets. Rafa played even worse against Grigor, especially the third set
tie-breaker. Rafa has blisters.
Courts are playing faster than before. Roger needs to take time away from
Rafa. I think that will be the key to winning the match.
Coming to predictions part, let me give it slightly differently.
If the match is over in 3 sets, winner is Fed.
If the match goes all the way to 5 sets, winner is Rafa.
If the match involves exactly 4 sets, winner can be either one.
I think the match will last only 4 sets, which means I can't predict
the winner.
But I vote for Roger in 4, as this is his best chance in a long time both to
beat Rafa and to lift another GS trophy.
Finally, remember that the last time Mirka was pregnant Roger lifted the trophy.
(this is height of tennis analysis; But, it is not just me, Roger himself reminded about
this to everyone in a recent interview).
