Wozniacki overcomes early deficit to knock off Yastremska

Caroline Wozniacki has continued her farewell tournament by overcoming a 5-1 first-set deficit and beating Dayana Yastremska 7-5, 7-5 on her sixth match point in the second round.

Wozniacki has said she plans to retire after this Australian Open. The 2018 champion had three match points in the 10th game of the second set but Yastremska held in a game after she'd taken a medical timeout to treat her left leg.

Wozniacki eventually clinched it two games later with a service break, and wiped tears from her eyes.

Former No. 1-ranked Wozniacki will next play Ons Jabeur, who beat Caroline Garcia 1-6, 6-2, 6-3.
