Anna Wintour essentially lives at the U.S. Open during the American Grand Slam to watch Roger Federer’s matches, but this year she went even further to support her proven favorite player. Wintour traveled to Miami for the Sony Ericsson Open at the Crandon Park to dine with Federer and watch his third round match yesterday. And when he wasn’t playing, she sat on the stands with son Charlie to watch someone other than the Swiss superstar on court–the editor supported Scot Andy Murray, who ironically beat her favorite a painful four times in a row.
