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