A 50th Grand Slam semi-final for Novak Djokovic

Novak Djokovic won 4-6 6-4 6-3 6-4 after 3h37′ of the match. But at the end of the first set, no spectator at the Rod Laver Arena would have bet a single dollar on the Serb’s chances of victory. He was, in fact, injured on the first point of the ninth game at 4-4 before, after a medical timeout, losing this initial round on one leg.
