Complete matches:
Nole over Polansky in straight sets: Nole was only as good as he had to be, but Polansky deserves a lot of credit for bringing his "A" game and making the match appear close, at least on paper. It is nice to see Nole hitting strokes with such depth again, but he will need to be better from here on out.
Shapovalov over Fognini in straight sets: Rain delays, of which there were two long ones with a third threatening all afternoon, have some advantages. This match got kicked to a cosy backcourt and, despite weather interruptions and recurring nearby thunder, it was a dandy. Denis won the first set easily. In the second set, Fog sauntered off to a 4-love lead looking like a colossus, and then Denis just reeled him in and won 7-5 with Fabio playing a minor villain along the way. The thing is Denis won the match from the backcourt which against a player as accomplished as Fognini is no small accomplishment.
Zverev over Klahn in straight sets: Sascha really does look like the deluxe edition--everything you could possibly want in a tennis player except the volley. Klahn kept it respectable, but the issue never really was in doubt.
Last bits of:
Tsitsipas over Thiem in a third set tiebreaker: Tsitsipas, fairly new to hard courts, looked more comfortable than Thiem on them. As I said before, Stefano learns fast, and he has some pretty impressive weapons, not the least of which is his ability to place balls just about anywhere he wants them. Like a lot of the new guys, he needs to put on about fifteen pounds, but he may become one of the top threats in the game in the long run.
Anderson over Donskoy in a third set tiebreaker: This match was played in a deep backcourt so I could virtually stand up next to the fence and watch them. Anderson served for the match, choked badly with a couple of double faults and lost his serve just like the old Kevin, but then blew Donskoy away 7-0 in the tiebreaker doing everything but beating him with a shoe in the process. The story here, standing like ten yards away from him, was how thorough and how deep Anderson's concentration was. He was like somewhere totally within himself. Oddly impressive to watch.
Side note: for a city that prides itself on being the multicultural flagship for the world, there are sadly very few people of colour at this tournament. The crowd could be a Trump rally. The only darker skinned folks that one sees are in menial jobs or as volunteers. Tennis has a lot of work to do in this area, but it never quite seems to get around to doing it.
