CiCi Bellis is making a great Grand Slam return in Australia. After being away from the game for almost two years, she's into the third round after upsetting No. 20 seed Karolina Muchova, 6-4, 6-4. The 20-year-old will next face No. 16 seed Elise Mertens.

Before the Australian Open began, the concern was poor air quality and unhealthy playing conditions. But now, it's dusty rain that put a damper on Thursday's action. The rain forced workers to pressure wash the courts to clear the dust.

Dominic Thiem suffered a hiccup in his second-round matchup against Alex Bolt. He was still able to regroup and finish strong to post a 6-2, 5-7, 6-7(5), 6-1, 6-2 win. Thiem's next round will be no picnic, as he will face Taylor Fritz.

Rain showers and a nosebleed that required medical treatment couldn't detour Daniil Medvedev. The Russian dismissed qualifier Pedro Martinez, 7-5, 6-1, 6-3, to advance to the third round. Medvedev smashed 40 winners and only hit 25 unforced errors.

World No. 7 Belinda Bencic rallied her way past 2017 French Open champion Jelena Ostapenko. It was a battle that consisted of shaky service games and quite a few unforced errors, but Bencic found a way to win, 7-5, 7-5.
