When Thanasi Kokkinakis and Nick Kyrgios squared off in the Australian Open junior final back in 2013, and won the Wimbledon boys’ doubles title together a few months later, no one would have expected they would have to wait another nine years before they played each other in a tour-level match. The Aussie duo are good friends and have formed a formidable doubles partnership this season, which saw them clinch the Australian Open crown in January, along with the title in Atlanta last month. Ad They haven’t been on opposite sides of the net on a match court since a Challenger meeting Kyrgios won in 2014, but that will change on Monday night in New York when they face off on Arthur Ashe stadium in a highly-anticipated US Open first round.
