Nick Kyrgios has overcome a wardrobe malfunction and serving arm soreness to safely progress to the Australian Open third round in Melbourne.

The colourful youngster swept aside Uruguayan claycourt specialist Pablo Cuevas 6-4 7-5 7-6 (7-2) in one hour and 58 minutes on Wednesday night despite engaging in a running battle with his own entourage over a problematic pair of shorts.

The pockets were seemingly not deep enough to contain balls, leaving Kyrgios needing to fetch one from a ballboy between first and second serves. He fumed at his camp for taking a set and a half to find a replacement pair before finally taking a toilet break almost an hour into the contest to change pants.

Cuevas protested at chair umpire Carlos Ramos, but to no avail as Kyrgios returned a new player to dominate the rest of the match and set up a third-round clash with Czech sixth seed Tomas Berdych.
