APTA, the American Paddle Tennis Association, is the governing body for the sport of Paddle Tennis in the United States. The sport of Paddle Tennis is a cross between tennis and squash played outdoors, primarly in the winter months, in a court with mesh walls that the ball can be played off. Each year they host a national tournament where ranked teams compete for the national championship. In 2008, APTA solicited Graymatter to develop the tournament logo for the event being held in Rochester, New York.
