Caroline Wozniacki will play the world number one Simona Halep in the Australian Open final after securing a 6-3 7-6 victory over Elise Mertens.
Halep edged a topsy-turvy semi-final against Angelique Kerber 6-3 4-6 9-7 and is 4/6 to beat Wozniacki, while the Dane is 6/5 to come out on top.
Halep claimed victory against her German opponent on her fourth match point. Neither Halep nor Wozniacki have won a Grand Slam title before and the winner of the final in Melbourne will end the tournament as the world's number one.
Wozniacki has won more than 25 WTA titles during her career but has only recently returned to her best form after enduring a difficult 2016 when she slid down the world rankings.
"I got really tired at 5-4," she said after getting the better of Mertens. "After the two first good serves, I thought, 'Calm down, it's all good', then it kind of wasn't good any more.
"I felt like my legs were shaking a little bit. I was like okay 'This is not normal, I'm not sure what I'm supposed to do now'. I just took a few deep breaths and once she had set point, I said, 'Well, I guess it is the third set. I guess now you just need to go for it'.
"It is going to be really difficult in the final, but I'm there and at that point it's the last match."
