Apostolos, also his son's coach, looked stunned and went to sit in the stands, clutching his bruised right arm.

"It happened accidentally. I didn't mean to do it and straight away forgot about it and moved on from there," Tsitsipas told reporters after the 7-6 (9-7) 6-7 (3-7) 7-6 (7-5) loss in Brisbane.

"It happens, I wasn't aiming to do that. It just went out of control, unfortunately.

"Maybe I'll stay in my room for three days, grounded by my father," he joked.

"I've done some stupid things as well in the heat of the moment, so it was obviously an accident," he said after Australia's 3-0 victory in the tie.
