Defending champion Jannik Sinner has moved into the quarterfinals at the Australian Open after beating Holger Rune during a match slowed down by medical timeouts for each player and a delay because the net got knocked loose.

Unseeded Lorenzo Sonego made it two Italians in the quarter-finals when he defeated hobbling 19-year-old American qualifier Tien 6-3 6-2 3-6 6-1, having also taken out Brazilian young gun Joao Fonseca in the second round.

World No.1 and defending champion Jannik Sinner, Iga Swiatek, Elina Svitolina, Elena Rybakina and other big players will be in action on Day 9 of the hard court major at the Melbourne Park.

They also have a dead-even head-to-head record. Keys won their first two matches, and Rybakina came back to win the next two, including their only meeting of 2024, on hard courts in Miami. Keys has won eight straight matches in Adelaide and Melbourne, while Rybakina, with new coach Goran Ivanisevic, hasn’t dropped a set this week.
