Australian Nick Kyrgios has won his way through to the third round of the Cincinnati Masters, with a three-set win over Ukrainian Alexandr Dolgopolov.
Kyrgios fought back from a break down in the first set, to complete a 6-3, 7-6 win.
The 21-year-old handed Dolgopolov the early break with a double fault to trail 3-1 in the first set. However, the Australian then reeled off five straight games, to claim the opening set, before winning the second 8-6 in a tiebreak.
Kyrgios will next face big serving Croatian Ivo Karlovic, who upset eighth seed, Jo-Wilfred Tsonga.
