MELBOURNE, Australia -- Reigning Australian Open champion Jannik Sinner's quest for a third consecutive title Down Under lasted just two sets on Day 3 after his opponent Hugo Gaston was forced to retire. Naomi Osaka also headlined the night session with a jaw-dropping arrival that sent the tennis world into a frenzy.

Earlier in the day, American duo Madison Keys and Ben Shelton booked their tickets to the second round with straight-sets victories on Rod Laver Arena. However, Alex Michelsen and Joao Fonseca were sent packing from the tournament.

Eyes were also locked on the wait times and queues that have marred the opening days of main draw action, with fans voicing frustration about just how busy the precinct is. Some spectators were forced to wait in excess of two hours just to enter Melbourne Park on opening Sunday and Monday, then another hour to enter the show courts.

Catch up on all the latest news, results, and more from Day 3 at the Australian Open.
