Andy Murray won a gruelling late-night contest with Grigor Dimitrov to reach his sixth consecutive Australian Open quarter-final.
The British number one came through 6-4 6-7 (5-7) 6-3 7-5 in three hours and 32 minutes at Melbourne Park.
A fifth set had looked likely but Murray won the last five games in row, sealing victory with a forehand that clipped the net and dropped over.
He goes through to face Australia's Nick Kyrgios in the last eight.
