The match lasted exactly two hours, which was twice as long as the Serb spent on court in his first round stroll against Damir Dzumhur, where he lost just three games. A backhand winner eventually secured victory for Djokovic but the result was in doubt for a long time, with the Serb only breaking Fucsovics in the tenth game of the second set to ensure the match went into a final set shootout. Djokovic will play either Russia's Andrey Rublev or Nikoloz Basilashvili of Georgia in the quarter-finals.
That pair play later on Wednesday. If he wins his last eight match, Djokovic is on course to meet Stan Wawrinka in the semi-finals after the Swiss also won on Wednesday, beating Chile's Nicolas Jarry 6-4, 7-6 (7/3).
