This is bottom of the barrel sledging from Nick Kyrgios.
The Australian tennis player plumbed new depths on Wednesday night, as he tried to wind up his opponent by claiming a rival player had slept with his other half.
In a remark picked up by a court-side microphone, Kyrgios made the allegation to Swiss rival Stan Wawrinka about his girlfriend [Donna Vekic] and 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…[it was] 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…
What was said I wouldn't say to my worst enemy.
To stop so low is not only unacceptable but also beyond belief.— Stanislas Wawrinka (@stanwawrinka) August 13, 2015
