Jason Kubler has become one of the sport’s fastest risers, with another huge jump in the latest ATP rankings.

In less than a month, the Queenslander has shaved his ranking from No.921 to No.349 after incredible success on the Australian Pro Tour, where he’s won 16 of his past 18 matches.

The latest move was 266 places up to No.349 thanks to last week’s victory at the Traralgon Challenger, his highest ranking since September 2015.

His career-best mark is 136th, set back in November 2014.

The man Kubler beat in the Traralgon final, Alex Bolt, improved his ranking by 49 places to No.230.

Meanwhile, at the Ho Chi Minh City Challenger in Vietnam, deep runs for John Millman and Akira Santillan have boosted their respective rankings.

Santillan, who reached the semifinals, cracked the top 150 (at No.148) after rising 14 places, while Millman, the runner-up, jumped 30 places to No.188.

There were several other Aussie men making moves following good results in Traralgon:

Among our women, Olivia Tjandramulia was the most notable improver, rising 20 places to No.391 after the points from her recent quarterfinal at the $25,000 ITF event in Hamamatsu, Japan were factored into her ranking.
