Australian tennis star Nick Kyrgios beat world number six Stefanos Tsitsipas at the Halle Open

Australian tennis star Nick Kyrgios beat world number six Stefanos Tsitsipas at the Halle Open, smashing his racquet and arguing with the umpire during the match.

The Australian, ranked 65th, came back to beat Greek Tsitsipas 5-7 6-2 6-4.

27-year-old Kyrgios smashed his racquet after losing the opening set in Germany and then got into an argument with the chair umpire in the second set and received a warning for time-wasting, a delay he said was due to needing to wipe sweat from his hands.

It was a second successive quarter-final for Kyrgios as he prepares for Wimbledon, having gone on to reach the semi-finals in Stuttgart last week, and he will face Spanish sixth seed Pablo Carreno Busta next.
