The Marlins drew quite a bit of attention when they decided to sell unused tickets to Saturday night's game against the Phillies. In the game, Philadelphia ace Roy Halladay threw a perfect game. In the first five hours more than 3,500 tickets were sold. The full price tickets will remain available through season's end. "We have never sold this product before, so we had no way of understanding what the demand would be or how long it would last," team president David Samson said.
