Defending champion Jannik Sinner put any illness worries to bed by crushing home hope Alex de Minaur in a straight-sets rout to tee up an Australian Open semi-final against Ben Shelton. The Italian World No. 1 showed no signs of the health issues that hampered him in his last match to emphatically fly past the eighth seed 6-3, 6-2, 6-1 on Rod Laver Arena. 

He will meet stubborn American Shelton for a place in Sunday’s final against either 10-time champion Novak Djokovic or second seed Alexander Zverev. Shelton, seeded 21, battled past another Italian, the unseeded Lorenzo Sonego, 6-4, 7-5, 4-6, 7-6 (7/4) to make the Melbourne Park last four for the first time.
