Jannik Sinner is through to the Australian Open quarterfinals after a drama-filled fourth-round win over Holger Rune. World No. 1 Sinner won in four sets, 6-3. 3-6, 6-3, 6-2, but this did not tell the story of a contest defined by illness.

Jannik Sinner will have to go past Ben Shelton to move one more step closer to his second Australian Open trophy on the trot. The Italian and the American youngsters will meet in the semifinals, scheduled on Friday (January 24).

Defending champion and No. 1 seed Jannik Sinner easily dispatches host country's last hope; Ben Shelton takes on-court interviewers to task.

Swiatek will face No. 19 Madison Keys of the U.S. on Thursday night for a berth in the final. The other women’s semifinal is No. 1 Aryna Sabalenka, the two-time defending champion, against her good friend, No. 11 Paula Badosa.

Ben Shelton has reached his first Australian Open semifinal by defeating Lorenzo Sonego 6-4, 7-5, 4-6, 7-6 in an entertaining match

In the quarterfinals, Sinner will face No. 8 Alex de Minaur of Australia, who ousted American Alex Michelsen 6-0, 7-6 (5), 6-3. It will be the first quarterfinals appearance for de Minaur in his home country's Grand Slam, and he became just the third Aussie man to reach the round in 20 years.

First came the medical timeouts, one each for Jannik Sinner and Holger Rune with the temperature above 90 degrees Fahrenheit (32 Celsius) at the Australian Open. Then came the unusual sight of a 20-minute delay because the net at Rod Laver Arena detached from the court after being hit by a big Sinner serve.

Australia’s biggest hope, Alex de Minaur, reached the Australian Open quarterfinals for the first time in his career, becoming the first Australian male to do so since Nick Kyrgios in 2015.

MELBOURNE – If someone is required to dismantle a nation’s hopes, then Jannik Sinner is a fine choice. He will do it without fuss. He will not beat his chest, prance in victory or even grunt. He will simply not miss. He will bring cold calculation, a Gatling-gun forehand, a face that tells you nothing and puncture your challenge.
