Melbourne VIC, Australia, 23 August 2016 | tennis.com.au

Bernard Tomic has returned to the top 20 after his quarterfinal finish at last week’s Cincinnati Masters.

The Queenslander rose two places to No.19 to rejoin the elite group, just a week out from the US Open.

Tomic is now just two spots below his career-high ranking of 17th, set in January.

Another Queenslander, John Millman, rose 10 places to No.81 after reaching the second round in Cincinnati as a qualifier.

He is now the third-ranked Australian, leapfrogging Jordan Thompson who sits in fourth.

Yet the biggest mover among the men was Christopher O’Connell; the Sydneysider rose 43 spots to a new career-high ranking of 346th.

O’Connell has been competing in a swing of ITF Futures events in the Balkans; in five events throughout Serbia and Macedonia, he has reached at least the quarterfinals at each, winning the title in his most recent outing in Novi Sad.

The 22-year-old has won 17 of his past 20 matches and has risen nearly 100 places in the rankings in the last month.

The biggest women’s mover this week was Lizette Cabrera.

Cabrera, 18, vaulted 93 spots to a career-high ranking of 470th after qualifying for the $25,000 ITF event in Gatineau, Canada then progressing to the semifinals.

The Queenslander has posted an impressive 12-5 record in her recent tour through North America.

Another improver was Alison Bai, who moved up 18 places to 358th – and up to No.9 in the Australian rankings.

Olivia Rogowska ascended 16 rungs to world No.406 after reaching the quarters in Gatineau, where she lost in three to Cabrera.
