Opinion: Mardy Fish isn’t easy to recognize these days. When I walked onto the Grandstand this afternoon, Fish and his opponent, Jan Hajek, were facing each other at the net, waiting for the coin toss. I knew, in theory, that Fish was the taller of the two, but I was still a little stunned to see what this 30-pounds-lighter version looked like in person.
