Casey Dellacqua and Olivia Rogowska have today both risen to career high WTA rankings.
Dellacqua has moved up three places to world number 33, while Rogowska is up four spots to number 106.
Both players are arguably in career best form this year and appear to be going from strength to strength as the season unfolds.
Dellacqua made the Round of 16 at the Australian Open, falling to Wimbledon finalist Eugenie Bouchard, before making the Indian Wells quarter finals. She then also enjoyed a run to the semi finals of the AEGON Classic in Birmingham, defeating fellow Australian Sam Stosur along the way.
Rogowska has won two ITF Pro Circuit titles this year, with the first coming on home soil in Launceston. A fortnight ago she won the Sacramento $50,000 event in California and then teamed up with Michaella Krajicek to win the Carson Classic doubles last week.
