Cincinatti: Swiss tennis star Stan Wawrinka said Australian Nick Kyrgios has not apologised to him for his on-court 'banged your girlfriend' sledge.

Kyrgios was fined $12,500 by the Association of Tennis Professionals (ATP) and further punishment may still be forthcoming after he jibed at his opponent, World No.5 Stan Wawrinka during a match in Montreal last week saying, "(Thanasi) Kokkinakis banged your girlfriend. Sorry to tell you that, mate".
