I'm watching the Nadal comeback, "just because". Of course Medvedev choked. But Nadal also won with commitment, experience, and getting his level back up to where it was in the 2nd set, with Medvedev making tons of UFEs. But if Nadal hadn't come out of the gate in the 3rd with so many UFEs, he wouldn't have had to work so hard to get it back in the 3rd. With his back against it, Nadal cleaned up his act. Surely, Medvedev failed to hold up his end, but there is something to be said for experience, and also enduring the relentlessness of a competitor like Nadal. Cali argued with me that it was in part experience that won Nadal the USO. Surely it was in part experience that won him the match today, on a less-favorable surface.
