A rare tennis scene at the ATP Cup between Australia and Greece in Brisbane with Nick Kyrgios judged the calmest player on court

He's beaten Stefanos Tsitsipas in three tie-breaker sets across more than two-and-a-half hours.

After dropping the first set, Tsitsipas slammed his racquet into the bench, accidentally clipping his dad on the forearm.

Mum had to step in from the stands to give him a finger-pointing lecture.

There was some recidivist behaviour - and another spray from mum - in the second set.
