At Grand Slams, Serena and Rafa often are like hurricanes, gaining strength and intensity as they advance. But I’m still hoping Medvedev can get past Dimitrov and pull off the upset. He has now bowed down before the almighty New York crowds – unfortunately, in my view, as it was fun to see somebody take them on, even though I didn’t like the way he treated that ball kid. In appearance he’s the opposite of Rafa – clothes hanging on his thin frame, long strands of hair accentuating his receding hairline. (Nadal’s balding too, but more aggressively on the top.) His head is large, his face intelligent; instead of Center Court at the U.S. Open, he looks like he should be in a Chekhov play.
