Nick Kyrgios claimed his second British scalp in the space of three days after winning his second-round match of the Fever-Tree Championships at Queen's Club against Kyle Edmund.
The Australian ruined Andy Murray's long-awaited comeback in a gruelling clash on Tuesday, and was forced into another deciding set against the British No 1, but produced a serving masterclass with 32 aces and faced only one break point to reach the quarter-finals of the Wimbledon warm-up event for the first time.
The opening two sets were shared in a couple of tie-breaks before Kyrgios stepped on the gas in the third to come away with a 7-6 (7-3) 6-7 (5-7) 6-3 victory.
The first set was totally dominated by serve with a total of 17 aces bombed down and only 10 points won by the returner.
Two of those came from Kyrgios in the tie-break, however, which put him in charge as he claimed it 7-3.
Edmund, who was looking to reach the last eight of the tournament for the second time in three years, failed to take a break point opportunity in the first game, and then found himself staring at the exit door, but Kyrgios inexplicably spurned a chance in the ninth game before failing to capitalise on a couple more break points two games later.
The 23-year-old world No 21 was made to pay for failing to convert his chances as Edmund stayed cool in the subsequent tie-break to level things up.
The momentum appeared to be with the Brit until a lack of concentration and a couple of loose points in the fourth game handed Kyrgios a vital breakthrough which he wasn't going to relinquish.
Kyrgios, who pushed Roger Federer to three sets before narrowly losing in the Stuttgart semi-finals at the weekend, continued his fine grass-court form by nailing his second match point with a booming backhand up the line to march on in west London.
He will play defending champion Feliciano Lopez for a place in the semi-finals after the Spaniard was handed a walkover when Canadian Milos Raonic, a 2016 runner-up at Queen's, injured his shoulder.
Novak Djokovic progressed to the quarter-finals with a dominant 6-4 6-1 victory against a lacklustre Grigor Dimitrov to secure a seventh victory from their eight career meetings.
The 12-time Grand Slam champion, appearing at the event for the first time since 2010, secured a decisive break to win the first set and took control of the second set with some assured baseline hitting before closing out the encounter on his fourth match point.
Djokovic will face Adrian Mannarino in the last eight after the world No 26 defeated compatriot Julien Benneteau 7-6 [7-4] 6-3 in one hour and 52 minutes.
