Charleston, SC, United States, 1 April 2019 | tennis.com.au

Ajla Tomljanovic is seeded 14th at this week’s WTA tournament in Charleston, one of three Australians in the main draw.

The world No.40 is joined by Astra Sharma and Destanee Aiava in the main draw of the Premier-level event, played on green clay courts.

Tomljanovic opens against Poland’s Magda Linette and is projected to meet No.1 seed and 2016 Charleston champion Sloane Stephens in the last 16.

Tomljanovic arrives at the tournament following a third-round run in Miami.

Sharma, meanwhile, extended her winning streak to seven with a three-set win over Shuko Aoyama in the final round of qualifying.

The West Australian, who prior to Charleston won the ITF $25,000 event in Irapuato, Mexico, lines up against Taylor Townsend in the main draw.

The winner goes on to face seventh seed Julia Goerges.

Aiava has drawn a tough opening-round opponent in No.9 seed Belinda Bencic after beating Czech Tereza Martincova 6-3 6-1 to qualify.

Like Sharma, Aiava is currently on a seven-match winning streak after winning the recent Australian Pro Tour title in Canberra.

Aiava plays Bencic on Charleston’s Stadium Court on Monday, with Tomljanovic and Sharma featuring back-to-back on the tournament’s Althea Gibson show court.
