The view over the practice courts at sunset. Yes, those are two rockets in the distance, built as futuristic exhibits for the 1964 World’s Fair.

Li Na took a big swipe in the direction of her opponent, Laura Robson, who had upset her here last year. Li avenged herself, and will now face Jelena Jankovic.

Florian Mayer looks a little peeved at his opponent, Donald Young; maybe the German doesn’t appreciate cursing on the court. Mayer took his rage out with a three-set win. Next up is Andy Murray.

Sloane Stephens, and her nails, were in fine form against fellow American Jamie Hampton. Sloane advanced to the round of 16 for the first time at the U.S. Open. Can we officially call her a “big-stage player"?

The heat briefly got to Novak Djokovic and made him a little testy in the first set. But he recovered in time to win in routine fashion over Benjamin Becker. The draw has opened nicely for Nole; the highest seed left in his quarter is Tommy Haas.

Once again, a wrist issue derailed Juan Martin del Potro’s momentum from earlier in the summer. After losing to Lleyton Hewitt, del Potro said he was “sad” to have to leave his favorite tournament so early.

Don’t recognize this man? You’re not alone. It’s American Tim Smyczek, ranked No. 109. Yesterday he reached the third round of the Open. Writers everywhere are trying to keep those consonants in the right order.

Look at Milos Raonic, Andy Murray, Roger Federer: This sport is obviously all in the calves. This one, as well as the shadow on the court, is Smyczek’s.
