Nick Kyrgios has survived a slip-up to secure a spot in the third round of the Australian Open.
The Australian No.2 beat crafty French veteran Gilles Simon 6-2 6-4 4-6 7-5 in an eventful second-round clash on Melbourne Arena.
Kyrgios appeared to be cruising to a comfortable win on Thursday night but dropped serve twice to lose the third set before recomposing himself to wrap up the match.
