World No.1 and defending champion Jannik Sinner, Iga Swiatek, Elina Svitolina, Elena Rybakina and other big players will be in action on Day 9 of the hard court major at the Melbourne Park.

It's an up-and-down day for favorites and the husband-and-wife duo of Gaël Monfils and Elina Svitolina wo their singles matches.

Elina Svitolina had two screws inserted into her ankle last September. Five months later, she's in the Australian Open quarterfinals.

After his historic win, Monfils returned to Margaret Court Arena and sat in the stands to watch his wife, Svitolina, eliminate the women's No. 4 seed, two-time major finalist Jasmine Paolini 2-6, 6-4, 6-0 at night.

The final match of the day saw American Learner Tien, playing in his first major outside of the U.S. Open, upset No. 5 seed Daniil Medvedev in a five-set classic, 6-3, 7-6, 6-7, 1-6, 7-6, that ended at 2:54 a.m. local time. Medvedev had reached three of the past four Australian Open finals, but could not fend off a ferocious Tien.

The five-time Grand Slam champion coasted into the third round of the Australian Open in straight sets on Thursday.
