VINE: Nick Kyrgios tells Stan Wawrinka a rival tennis player ‘banged your girlfriend’

Bottom of the barrel trash-talking picked up by TV cameras.

Australian tennis player Nick Kyrgios plumbed new depths, last night, as he tried to wind up his opponent by claiming a rival player had slept with his girlfriend. Kyrgios, who last garnered headlines, in June, for not giving a toss for a losing set during his exit from Wimbledon, directed his tirade at Swiss player Stan Wawrinka. In a remark picked up by a courtside microphone, Kyrgios made the allegation to Wawrinka about his girlfriend [said to be Donna Vekic] and teenaged Australian player, Thanasi Kokkinakis. 'Kokkinakis banged your girlfriend,' he declared, midway through the second set. 'Sorry to tell you that, mate'. Tackled on the comments, after his victory [Wawrinka retired with a back injury], Kyrgios explained, 'He was getting a bit lippy. 'Kind of in the heat of the moment. I don't know [why]. I just said it.' Later, two-time Grand Slam winner Wawrinka took to Twitter to give his take on the Australian's bluster. https://twitter.com/stanwawrinka/status/631705977050505216
