Melbourne, Australia, 4 March 2013 | tennis.com.au

Nick Kyrgios’ reward for his win at the Nature’s Way Sydney Tennis International has been an incredible rise of 229 places in the latest ATP rankings, vaulting him to 330th in the world.

His stunning win at the ATP Challenger event as a wildcard ensured he would peak at a career-high mark when Monday’s rankings were released.

Just one month ago, Kyrgios was ranked No.843.

Yet since that time, a semifinal run at the West Lakes ATP Challenger in Adelaide, a quarterfinal finish at the ITF Futures event at Melbourne Park and now the title in Sydney have all contributed to his rapid rise.

The 17-year-old from the ACT is now Australia’s 14th-ranked male player.

Also enjoying a career-high ranking this week was Sam Groth, who rose 41 spots to world No.189 after reaching the semifinals at the Sydney Challenger (and also factoring in his recent run to the title on grass at the ITF Futures event in Mildura).

Groth fell in the Sydney semifinals to Matt Reid, who himself enjoyed a vastly-improved position on this week’s ranking list – the New South Welshman jumped 55 spots to No.230, also a career-high.

Several other Aussie men who made gains were:

• Bernard Tomic, who returned to the position of Australia’s top-ranked male (aided by Marinko Matosevic’s fall of 14 places after the Victorian was unable to defend his points for reaching last year’s Delray Beach ATP final)
• Matthew Barton and James Duckworth, who each rose 14 places after progressing to the Sydney Challenger quarterfinals (a career-high ranking of No.221 for Barton)
• Greg Jones, who jumped 26 spots to No.322 after reaching the quarterfinals in Sydney
• James Lemke, who rose 43 places to No.447 once his finals result from the recent Mildura ITF Futures event was taken into account.

There was little change in this week’s WTA rankings among Australia’s women, with Sam Stosur retaining her place in the top 10 – and the honour of being Australia’s highest-ranked player – at world No.9.
