Nick Kyrgios has seen off dogged Czech Radek Stepanek in four sets in a solid start to his Wimbledon campaign.
Australia’s 15th seed outclassed the Czech veteran 6-4 6-3 6-7 (9-11) 6-1 on Tuesday to preserve his flawless first-round record at the All England Club.
Kyrgios next plays dangerous German wildcard Dustin Brown on Thursday for a place in the last 32 for the third straight year.
