Two sets down and nursing an elbow injury, Jannik Sinner's Wimbledon looked done when the roof was closed on Centre Court.
Grigor Dimitrov was playing sublime tennis on Monday and the world No.1's five-set record would not have encouraged him, Sinner having lost six, won one.
Two games later Dimitrov, having just served an ace to tie up the third set 2-2, slumped to the ground holding the pectoral muscle on the right, serving side of his chest.
