Nick Kyrgios came through a potentially nasty setback to win in the fifth and deciding set against the talented Frenchman.

The maverick Australian slipped late in the fifth set and appeared to jam his hip, shouting out in pain and even with an expletive before eventually rising to continue play.

The match had been held over after being suspended at 11pm the previous night, the two locked at two sets and 3-3 apiece.

Kyrgios and Humbert both held serve until 7-7 in the decider, where the Australian converted a break point to serve for the match.

Humbert did not roll over, setting up two break points at 15-40 for a chance to level at 8-8. But Kyrgios held firm to stave off the Frenchman and secure a 6-4, 4-6, 3-6, 6-1, 9-7 win in just under three and a half hours on-court.

Prior to Wimbledon, the Australian had not played a competitive match for five months, last taking to the court at the Australian Open, where he also beat Humbert in five sets.

Meanwhile, Ugo Humbert entered The Championships off the back of a biggest career title in Halle, defeating two top-10 opponents on the way in Alexander Zverev and Andrey Rublev.

Nick Kyrgios will next take on Italian Gianluca Mager for a place in the third round.
