The Australian Open 2020 got off to a frantic start on Monday with the top brass in both men's and women's singles dishing out some superb performances.
The likes of Novak Djokovic, Roger Federer Naomi Osaka and Serena Williams registered easy wins.
The momentum was carried on to Day 2.
Several big guns progressed to the second round.
Here are the major happenings.
Problems continue for Maria Sharapova
Five-time Grand Slam champion Maria Sharapova's first-round exit means she is set to drop out of the world's top 350.
The Russian, who won at Melbourne Park in 2008, lost 3-6, 4-6 to Croatian 19th seed Donna Vekic.
It was Sharapova's second outing since September's US Open because of a shoulder injury.
She isn't sure whether this could be her last appearance here.
Women's singles: Pliskova, Keys and Bencic progress
World number two Karolina Pliskova overcame Kristina Mladenovic 6-1, 7-5 to reach the second round.
Pliskova maintained her 100% record this season after bagging the Brisbane International title this month.
10th seed Madison Keys beat Daria Kasatkina 6-3, 6-1. She was joined by sixth seed Belinda Bencic, who powered past Anna Karolína Schmiedlová 6-3, 7-5.
Ons Jabeur beat 12th seed Johanna Konta 6-4, 6-2.
I was fortunate to get myself to be here: Sharapova
"I was fortunate to get myself to be here and thanks to [the organisers for] allowing me to be part of this event. It's tough for me to tell what's going to happen in 12 months' time," said Sharapova, who was given a wildcard.
