Melbourne VIC, Australia, 4 August 2015 | tennis.com.au

John Millman’s ATP Challenger victory in Lexington at the weekend has propelled the Queenslander into the Australian top five.

Millman, who rose 12 places to world No.84 – a career-high ATP ranking – now sits behind only Bernard Tomic (26), Nick Kyrgios (38), Sam Groth (62) and Thanasi Kokkinakis (72).

He leapfrogs James Duckworth, who at world No.95 rounds out an impressive six Australians in the world’s top 100.

Also making tracks was young Victorian Omar Jasika, who jumped 22 places to 259th.

His rise came following his quarterfinal finish in Lexington, equalling his best-ever result at an ATP Challenger event.

Matt Reid, a winner on the ITF Futures circuit at the weekend in Saskatoon, Canada, this week vaulted 39 places to world No.416.

That rise actually took into account his final appearance at the Vancouver Futures event the week prior; his winning ranking points from Saskatoon are expected to be added to his tally next Monday, pushing him higher still.

Jacob Grills, who reached the semifinals at the recent Futures event in Duinbergen, Belgium, pushed up 23 spots to 575th.

In the WTA ranks, Alison Bai and Alexandra Nancarrow were Australia’s most notable movers.

Bai rose 16 spots to a career-high mark of world No.328, after qualifying for the biggest tournament of her career at the WTA 125K event in Nanchang, China.

Nancarrow’s latest rise – 31 places to 386th – came after she won the $10,000 ITF tournament in Palic, Serbia.

It was her fourth career ITF title – and third of 2015 – and all have come in Serbia.

Sally Peers rose 25 rungs to 517th after reaching the semifinals of the $10,000 ITF event in Maaseik, Belgium.
