Kaylah McPhee was one of several Australians this week making significant moves in the WTA and ATP rankings.

The 21-year-old Queenslander jumped 35 places to a career-high mark of No.209 after progressing to the final of the ITF 60K tournament in Jinan, China.

Now on the cusp of the top 200, McPhee has enjoyed an incredible season, beginning 2019 ranked 350th before going on to reach two finals, two semifinals and three quarterfinals.
