Melbourne VIC, Australia, 8 May 2018 | tennis.com.au

Jason Kubler has hit his highest ranking in three years after advancing the semifinals of last week’s ATP Seoul Challenger.

Kubler rose 19 places to world No.161, and is now within sight of his career-high ranking of 136th, set back in November 2014.

Kubler ultimately fell to fellow Australian Jordan Thompson in the Seoul semifinals; Thompson this week rose five places to world No.89.

Seven months ago, in the first week of October, Kubler was ranked 940th.

Yet since that time he has built a win-loss record of 42-11, including going 25-8 in 2018.

He is now the seventh-ranked Australian male behind Nick Kyrgios (23), John Millman (70), Matt Ebden (83), Thompson (89), Alex De Minaur (109) and Thanasi Kokkinakis (152).

Kubler is in action this week at the ATP Challenger event in Gimcheon, Korea, a hardcourt event.

Another player making gains was 18-year-old Jaimee Fourlis, who vaulted 44 spots to world No.224 after her victory in late April at a $25,000 ITF tournament in Italy.

Fourlis becomes the 10th-ranked Aussie female behind Ash Barty (18), Daria Gavrilova (24), Sam Stosur (57) and Ajla Tomljanovic; Tomljanovic improved 25 places to No.71 after progressing to the WTA final in Rabat.

Fourlis, now at a career-high ranking, will have a chance to improve that position after entering the main draw of the $100,000 ITF claycourt event in Cagnes-Sur-Mer, France as a lucky loser.

She’d earlier won two rounds of qualifying – taking her winning streak to seven – before falling at the final hurdle to Dayana Yastremska.

Lower down the rankings, Abbie Myers made a huge jump of 214 places to world No.427 after her run at last week’s $80,000 tourament in Gifu, japan.

Myers qualified for the main draw of the harcourt event and went all the way to the semifinals, where her six-match winning streak was ended by Japan’s¬†Moyuka Uchijima.
