Snapshot from day five at the Open

PLAYER OF THE DAY: Amanda Anisimova - the 17-year-old and youngest player left in the women's draw - blew 11th seed Aryna Sabalenka off the court 6-3 6-2 in a little over an hour to power in to the last 16, the youngest American to do so in Melbourne since Jennifer Capriati in 1993, and at any slam since Serena Williams in 1998.

STAT OF THE DAY: Roger Federer's 6-2 7-5 6-2 victory over Taylor Fritz was the Swiss marvel's 17th in a row at Melbourne Park and propelled the 37-year-old two-time defending champion into the fourth round for the 17th time in his past 18 attempts.

QUOTE OF THE DAY: "He's got a bit of time, sticks around, shows he's passionate about the game. That's what we need to see. But we wish he was on the court rather than a commentary booth," Federer on Nick Kyrgios' debut appearance in the Channel Nine courtside bunker.

TOURNAMENT SUMMARY: Amanda Anisimova's history-making feats aside, former winner Maria Sharapova eliminated defending champion Caroline Wozniacki in the third round to set up a meeting with home-grown favourite Ashleigh Barty. Greek firebrand Stefanos Tsitsipas will face Federer in the round of 16 after posting a foul-mouthed win over Georgia's Nikoloz Basilashvili.
