Nick Kyrgios is closing in on a career-high ATP ranking after a summer that confirmed a new-found resolve in the 22-year-old's attitude to tennis.
As Australia's top-ranked male player, Kyrgios sits at No.14 in the latest ATP rankings.
Kyrgios has improved three places after going into the Australian Open as the world No.17 where he was beaten in four tight sets in a round of 16 clash against then-world No.3 Grigor Dimitrov.
Kyrgios achieved his best ATP ranking of No.13 in the world at the end of 2016.
He slipped to No.24 during the middle of the 2017 season but will spearhead Australia's Cup tie against Germany this week with renewed confidence after winning the Brisbane International earlier this month.
Bernard Tomic's slide down the rankings continues, tumbling a further 25 places to No.168.
Matthew Ebden, a first-round Australian Open winner over world No.16 John Isner, has moved up four places to No.74 to be Australia's second-highest ranked player.
Rafael Nadal has kept his place as world No.1 although the gap has closed between himself and Roger Federer after the Swiss master's sixth Australian Open triumph.
