Melbourne, Australia, 12 February 2013 |

Aussies Matthew Barton and Nick Krygios have both enjoyed significant jumps in the latest edition of the ATP World Tour rankings after stellar performances at last week’s Charles Sturt Adelaide International.

Barton won the title at the $50,000 ATP Challenger event at Adelaide’s West Lakes Tennis Centre, with the unseeded 21-year-old winning his way through the draw to claim the biggest tournament victory of his career.

His reward was a jump of more than 100 places to a career-high ranking of world No.242, making him Australia’s 9th-ranked player.

Barton, who impressively did not drop a set all week in Adelaide – including a 6-2 6-3 dismissal of Brit James Ward in the final – says his improved ranking will hopefully allow him to contest Grand Slam qualifying events later this season.

He will also play increasingly on the ATP Challenger tour – he is entered into the Sydney Olympic Park Challenger event later this month and is expected to the follow the Challenger circuit to Japan.

Meanwhile, shortly after claiming the ITF world No.1 junior ranking, Nick Kyrgios has made waves at senior level, vaulting an incredible 267 spots after reaching the semifinals in Adelaide.

The 17-year-old, who has played just 11 senior events in his fledgeling career – and who thanks to a wildcard was contesting his first Challenger-level tournament – is now ranked world No.576.

Kyrgios upset No.6 seed Brydan Klein in the opening round at West Lakes before falling in three sets to Ward in the semifinals.
