U.S. Open: Finally! A women's barnburner

Well, I'm not going to feign surprise about Venus Williams' loss in the fourth round yesterday. My draw had her bowing out to Karolina Pliskova from the beginning. One thing that did surprise me was the quality of the match -- on Venus' part. She has a tendency to go off the rails in an effort to go for her shots, but lately she's been able to do that and keep the ball in the court. In my estimation, even when she was destroying everyone on tour, her game wasn't as strong as it is now. She and Pliskova both played unbelievable tennis, especially when things got tight for both of them. OK, that backhand crosscourt by Venus on her third match point down? And the forehand up the line by Pliskova in the same spot? WHAT?! That was finally our high-level women's match of the tournament.
I thought there was a chance Agz Radwanska/Ana Konjuh would reach that level, but Konjuh apparently had to get back to the hotel and watch some Degrassi because she handled Radwanska with the quickness. This is one situation where the score (6-4, 6-4) did not reflect the match, because it seemed that Konjuh ran away with the thing. So it looks like Konjuh's going to be a handful for the next person playing her -- Pliskova. That should be fun.
There are a couple of good day matches lined up today, along with Caroline Wozniacki v. Ana Sevastova and Novak Djokovic v. Jo-Jo Tsonga at night. I know we just had a holiday weekend, but I am wondering if it would be low-class to take another day off with sickness. Because:
Angelique Kerber v. Roberta Vinci: This has No. 1-ranking implications for Kerber. Basically, all she has to do is win the U.S. Open and she'll be the best player in the world! So easy! And against Vinci? Oh please. Of course she'll roll against her. I mean, last year, Vinci just ... oh. Hm. Hmmmm.
I definitely feel a fever coming on.
Lucas Pouille v. Gael Monfils: Now I have the chills and a slight cough. Achy throat. Reaching for my cell phone.
