Well, one semifinal is done, and fast. The conditions entered the picture big time. Very windy. Dolgopolov hung in there for about 1/2 set, but he was clearly uncomfortable in the wind and finally got broken, and Roger finished the first set 6-3. After that, Federer's play even got better, and Dolgopolov was left talking to himself, getting broken in his first service game in the second set, then getting broken again in a very long service game for 4-1, then again to lose the second set 6-1.
Federer had 12 winners and 12 unforced errors, which was very very good for the windy conditions. Dolgopolov had 12 winners and something like 25 unforced errors and as usual a poor 1st service in percentage (maybe 40%?) that he couldn't overcome.
He was basically schooled in these conditions, which was unfortunate for Dolgopolov who was playing better than that, but I'm sure it was a good learning experience, and for making it to the semi's he still earns over $200,000, so not so bad on the whole.
If it stays windy, I think Djokovic is going to have a difficult time. Wind usually favors the better server as long as he doesn't have a high toss. But, who knows, right?
Respectfully,
