IT seems the recent sledging controversy in his match against Stan Wawrinka in Montreal is set to follow young Australian Nick Kyrgios to the US Open.
Kyrgios was fined $A13,500 for a crude remark directed at the dual major champion, and took to Twitter to express his remorse.
"I would like to take this opportunity to apologise for the comments I made during the match last night vs Stan," the 20-year-old tweeted the following day.
But that clearly wasn't enough to satisfy Wawrinka, who made his thoughts known yesterday after beating 18-year-old Croatian Borna Coric in three sets in the second round of the Cincinnati Open.
"Uh no, he (Kyrgios) didn't apologise, no. But I prefer not to talk about him. Thank you," Wawrinka (pictured) said when asked whether the matter was closed.
Coric is the first teenager to win 20 tour-level matches in a season since Aussie Bernard Tomic in 2012.
