The Australian booked her spot in the Korea Open final with a 6-4 5-7 6-4 victory over Hsieh Su-Wei.

It hasn't been the easiest of events for Tomljanovic, with all four matches she has played going to three sets and has seen fightbacks from opponents. 

The 25-year-old led Hsieh 6-4 4-2 and served for the match at 5-4 before a comeback was on.

It was a similar story in the quarterfinals as she led Mandy Minella 6-4 3-1 and trailed Alison Van Uytvanck in the final set of the first-round match.

Reaching the final could see Tomljanovic reach a career-high ranking of No.44, which comes three years on from her previous highest ranking of 47th. She dropped outside the top 100 at the end of 2017 after a shoulder injury required surgery in early 2016 and which sidelined her for more than a year.

Tomljanovic will face second seed Kiki Bertens, who brushed Maria Sakkari aside 6-4 6-2 in the other semifinal.
