Here are the reasons why Roger has a better chance this time against Novak.
1. Roger is serving well. He won over 80% of first serve points yesterday.
But, his serving is not as good as it was in Wimby'15.
2. Roger's forehand has found its mojo. This is an important difference compared to
last year's USO and W.
3. Roger's ROS has really become good (This is not a fannish statement, watch some
unbelievable returns of monster serves from Bird in the last set of yesterday's match).
This is the key difference compared to last years USO and W.
4. Roger is relatively fresh without any taxing matches so far. Extended to 4 just once
and that too in 3rd round which was long ago.
5. Roger's BP conversion used to suck in the recent past. That is also improving.
He had 50% in last match.
6. The courts are playing little bit faster.
7. The ball is staying low, making Roger's slices remain at shoe string level causing difficulty for opponents.
8. Novak's UFE is mounting. After 100 against Simon, he has cut it down to 27 against Kei. But, people need to realize that his differential is negative (-5) even in his straight set match against Kei.
Having said that, Novak is still the favorite. He has never went home without the trophy after reaching SF at AO. Further night match will tilt the advantage to Novak.
But, my gut feeling says Roger takes it this time.
