Henman beat Federer and Roddick, the two most recent Slam champs? Fluke? Not his problem they weren't good enough to beat him. Ferrer won the tournament when Djokovic, Murray, Del Potro and Wawrinka were in the draw. Also, not a fluke. Khachanov beat Zverev, Thiem and Djokovic and also earned his title.Sock isn't the only fluke win. It's the home of flukes. Henman, Berdych, Ferrer, Khachanov etc.
