He might be just 19 years old, but dramatic breakthroughs are already a theme for fast-rising Australian, Nick Kyrgios.

Having achieved the world No.1 junior ranking, Grand Slam upsets, early career titles and asserted himself as the youngest member of the worlds’ top 200, there’s now another milestone as Kyrgios makes his Australian Tennis Magazine cover debut.

Celebrating the “Breakthrough” June edition, the magazine explores how far Kyrgios has progressed already and why he’s maintaining a down-to-earth approach, even as excitement builds around his own success and that of his good friends Thanasi Kokkinakis and Jordan Thompson.

“We have to stay grounded, stay humble and keep working hard,” says Kyrgios, who will take another step forward as a main draw competitor at the French Open, which starts in Paris on Sunday.

Along with tireless support from award-winning coach Simon Rea, Kyrgios has drawn on the inspiration and expertise of major-winning compatriots Pat Cash, Pat Rafter and Lleyton Hewitt in his impressive career development.

Those same champions share some critical tips for players of all standards in

Australian Tennis Magazine, with a special “Lessons for tennis life” feature in which they pass on the one piece of advice that was instrumental to their own careers.

For some players, it’s the practical advice that will be most helpful – others share lessons that are as valuable to life, as they are to tennis. As Rafter writes: “the measure of success is not rankings or Grand Slam titles, but whether you have got the most out of yourself to be the best player you can be.”
