17-year-old Australian Thanasi Kokkinakis, ranked World No. 570, defeated Igor Sijsling 7-6(4), 0-6, 7-6(3), 6-2 on his Grand Slam debut at the 2014 Australian Open.
The youngster was visibly happy at securing a round 2 date against World No. 1 Rafael Nadal and went on a long victory lap around the court to thank the people. It was a milestone moment for Kokkinakis and his emotions were understandable, but it still made for a funny sight!
