Go to the stadium day of game. Fans, not only scalpers are always trying to unload unused seats. Keep walking, talking, bring a sign, and carry a seating chart with ya. The closer to game time and shortly after the game starts, you should be able to pick up a ticket for cost or less. If you are just looking for one ticket, easy. I have usually scored better seats at lower cost, this way in many different cities for all major sporting events.
