1. A ball for playing a modified game of baseball comprising:
an inner lightweight polyethylene spherical core,
the inner lightweight polyethylene spherical core having a hollow round center cavity and an outer spherical polyethylene shell enclosing the hollow round center cavity,
the outer spherical polyethylene shell having a rounded concave curved inner surface and an outer spherical surface opposite from the rounded concave curved inner surface, the rounded concave curved inner surface surrounding and encasing the hollow round center cavity,
the outer spherical polyethylene shell having a middle seam and a hole extended through the middle seam, the hole being in communication with the hollow round center cavity to allow air to move into and out of the hollow round center cavity,
the outer polyethylene spherical shell having a uniform thickness from the rounded concave curved inner surface to the outer spherical surface of between 1 millimeter and 3 millimeters to allow compression energy to be released from the inner lightweight polyethylene spherical core thereby controlling the flight of the ball,
a synthetic polyurethane leather cover attached to the outer spherical surface of the outer spherical shell,
the synthetic polyurethane leather cover surrounding and fully enclosing the inner lightweight polyethylene spherical core,
the synthetic polyurethane leather cover having a first figure-8 shaped polyurethane leather cover portion and a second figure-8 shaped polyurethane leather cover portion attached to the first figure-8 shaped polyurethane leather cover portion,
raised red colored double stitches attaching the first figure-8 shaped polyurethane leather cover portion to the second figure-8 shaped polyurethane leather cover portion thereby forming raised seams between the first figure-8 shaped polyurethane leather cover portion and the second figure-8 shaped polyurethane leather cover portion,
a layer of adhesive coating the outer spherical surface of the outer spherical polyethylene shell and located between the outer spherical surface and the first figure-8 shaped polyurethane leather cover portion and the second figure-8 shaped polyurethane leather cover portion to adhere the first figure-8 shaped polyurethane leather cover portion and the second figure-8 shaped polyurethane leather cover portion to the outer polyethylene spherical core, and
a layer of latex located between the first figure-8 shaped polyurethane leather cover portion and the second figure-8 shaped polyurethane leather cover portion and the outer spherical polyethylene shell,
the first figure-8 shaped polyurethane leather cover portion and the second figure-8 shaped polyurethane leather cover portion each having a white coloring to simulate a standard baseball,
the ball having a weight between 1¼ ounces and 1¾ ounces and a circumference between 9 inches and 9¼ to facilitate exaggerated swerving movements of the ball when thrown.
