Novak Djokovic has cranked up his Australian Open title charge, coolly dispatching fifth seed Andrey Rublev in straight sets to reach his 44th grand slam semi-final and 10th at Melbourne Park.
Nine-time champion Djokovic shook off any concerns about his lingering hamstring injury and gave short shrift to hecklers as he comfortably beat the Russian 6-1 6-2 6-4 in two hours and three minutes on Rod Laver Arena.
