Italian star Jannik Sinner is through to his second grand slam semi-final after overcoming Russian fifth seed Andrey Rublev in a late-night slugfest at the Australian Open.
The two heavy hitters went toe-to-toe on Rod Laver Arena, but the in-form Sinner proved too strong and secured a 6-4 7-6 (7-5) 6-3 win in a match that finished at 1.22 am on Wednesday morning.
