"I would like to take this opportunity to apologise for the comments I made during the match last night vs Stan Wawrinka. My comments were made in the heat of the moment and were unacceptable on many levels. In addition to the private apology I’ve made, I would like to make a public apology as well. I take full responsibility for my actions and regret what happened."
