Andy Murray defended Kim Sears: 'You can say stuff you regret'
While Kim has not publicly spoken about the incident, after the match Andy defended his fiancée by saying, "In the heat of the moment, you can say stuff that you regret."

"When there's a lot of tension surrounding something, which you created, it's completely normal that the whole first set everyone was tight," said Andy. "Even Tomas, who very rarely says anything on the court… there was tension there for him as well."
