I only read Kelly, to see how many times he opens his proverbial mouth to change feet.  I doubt Kelly paid for his ticket to the del Potro Federer match but watching on TV, del Potro had his share of supporters who didn't pay hundreds of dollars for their tickets and were not part of the super rich.  Just maybe the del Potro's fans were able to buy tickets because the venue has approx. 24k seats.  However, this Federer fan was hoping for Roger but kudos to Juan Martin for playing great.
