The Australian Open has reached the quarter-final stage in the singles, with the men’s and women’s favourites still standing despite early exits for other top seeds.
Daniil Medvedev is aiming to win a second straight Grand Slam, but he will not be in quarter-final action until Wednesday.
However, women’s favourite Ashleigh Barty will be playing on Tuesday, with Australia’s home hope out to beat USA’s Jessica Pegula as she continues her bid for a first Grand Slam on home soil.

Shapovalov raced past Zverev in three sets, 6-3 7-6 6-3, and after reaching the Australian Open quarter-finals for the first time, the 22-year-old Canadian will be aiming to beat Nadal for just a second time.
