This page shows the results of the Racquetball Competition for men and women at the 2003 Pan American Games, held from August 1 to August 17, 2003 in Santo Domingo, Dominican Republic. Racquetball is a racquet sport played with a hollow rubber ball in an indoor or outdoor court. Joe Sobek is credited with inventing racquetball in 1950, adding a stringed racquet to the game to increase velocity and control. Unlike most racquet sports, such as tennis, badminton or squash, there is no obstacle - net or tin - to hit the ball over. Also, the court's walls, floor, and ceiling are legal playing surfaces, with only the upper part of the back wall (above 12 feet) being out-of-bounds.
