The Australian tennis swing is heating up with the last major tournament before the grand slam - the Adelaide International.

It's not how you start, but how you finish. That's the lesson Mirra Andreeva taught everyone in the Adelaide final, as she dropped the first three games, but won nine in a row between the first and second sets to carry her to a straight-sets win over Victoria Mboko and capture her fourth career title.

Youth will be served in the Adelaide International final as teenagers Mirra Andreeva and Victoria Mboko square off Saturday in Australia. Third-seeded Andreeva, 18, advanced with a 6-3, 6-2 semifinal win Friday against ninth-seeded Russian compatriot Diana Shnaider in one hour and 24 minutes.

The second round matches are going to take place on Day 3 of the WTA Adelaide International, and many big names will be in action, including the defending champion, Madison Keys.

One year after Victoria Mboko’s breakout season delivered titles across three levels, the 19-year-old Canadian is already one win from completing another line on her rapidly growing résumé in Adelaide.

Mirra Andreeva was all business on the court today as the No. 3 seed annihilated home star Maya Joint 6-2 6-0 to reach the Adelaide International semifinal. Playing against the Russian for the first time, the 32nd-ranked Australian survived a tough opening service game after saving four break points.

Emma Navarro delivered a very clean display on Wednesday as the No. 6 seed ousted three-time WTA champion Yulia Putintseva 6-1 6-4 to safely reach the Adelaide International quarterfinal. Right out of the gate, the American tennis star put pressure on her Kazakh rival, claiming breaks in the second and sixth games to easily win the first set.
