On the one hand, I do have some sympathy for Medvedev cramping during his match and it was harsh of the umpire to give him a code violation for not trying. All that sympathy goes out the window with the total disrespect he shows umpires though. He did end up retiring in his match versus Tien, but I expect some more fines being assessed to Medvedev,
