Melbourne VIC, Australia, 1 March 2016 | tennis.com.au

Nick Kyrgios has returned to within a whisker of his career-high ranking after his impressive performance last week at the Dubai Duty Free Tennis Championships.

The Australian, who reached the semifinals before retiring in the second set of his match against Stan Wawrinka with a back complaint, rose six places to No.27.

His best-ever ranking of No.25 came in June 2015.

Two weeks ago, Kyrgios was ranked outside the top 40, but has risen 14 spots in the past fortnight after his first ATP title in Marseille and his semifinal finish in Dubai.

Prior to the Wawrinka loss he had built an eight-match winning streak.

Also showing impressive form is Bernard Tomic.

The Queenslander moved up one place to world No.20 after his final appearance in Acapulco, where he came very close to capturing his first ATP 500 title.

Also making a significant move was Jordan Thompson; the New South Welshman jumped 28 places to a career-high mark of 123rd.

Bearing down on the top 100, Thompson has also risen to No.7 in the Australian rankings.

Matthew Barton also enjoyed a rise, moving up 34 spots to No.239 after reaching the semis of last week’s¬†ATP Challenger tournament in Kyoto, Japan.

Arina Rodionova has been rewarded for her recent success on the Australian Pro Tour, rising 64 spots to No.260 in this week’s edition of the WTA rankings.

Rodionova won the Perth Tennis International #2 – the reason for her big rise – and followed that up with a run to the final in Port Pirie.

That result – which took her winning streak to nine matches before she fell to Austrian Barbara Haas – is expected to push her even higher next week.

Storm Sanders, who reached the semifinals at the Perth #2 event as a qualifier, vaulted 33 places to No.309.

Sanders returned to the Australian top 10 as a result of her rise.
