Apparently, Mirka Federer was way too much animated in Federer’s match with Stan Wawrinka in the ATP Tour Semifinal 2014. In the final stages of the game ES believes that Mirka had accused Wawrinka of whining. Wawrinka failed to convert 3 match points that too in the crucial service game at 5-4, before Federer took the match. He then backed out from the final apparently because he wasn’t “match fit”. Who knows there might be another reason to that!!
