Abstract

An instructional ball having a football-shaped body shaped as an ellipsoid having a longitudinal axis and a generally circular transverse cross section and a core.

1 . An instructional ball comprising:
 a football-shaped body shaped as an ellipsoid having a longitudinal axis and a generally circular transverse cross section; and   a core.   
   
   
       2 . The ball as claimed in  claim 1 , wherein the core of the ball is selected group consisting of plastic cork, rubber, and a combination thereof. 
   
   
       3 . The ball as claimed in  claim 1 , further comprising an outer core. 
   
   
       4 . The ball as claimed in  claim 1 , wherein the core is in the center of the body. 
   
   
       5 . The ball as claimed in  claim 1 , wherein the body is covered with two pieces of leather that are stitched together using 108 stitches of thread. 
   
   
       6 . The ball as claimed in  claim 1 , wherein the ball is about 5 ounces in weight. 
   
   
       7 . The ball as claimed in  claim 1 , wherein the ball has a cross section substantially similar to that of a regulation baseball. 
   
   
       8 . A method for improving a pitcher's ability to throw a ball in a sport comprising:
 providing the pitcher with an instructional ball having a football body shaped as an ellipsoid having a longitudinal axis and a generally circular transverse cross section and a core;   having the pitcher grip the ball; and   repeatedly throwing the ball, whereby the repetition allows the correct muscle groups to develop and to adapt to throw the gyroball pitch.   
   
   
       9 . The method of  claim 8 , wherein the sport is a baseball. 
   
   
       10 . The method of  claim 8 , wherein the sport is a softball. 
   
   
       11 . An instructional ball comprising:
 a body shaped as an ellipsoid having a longitudinal axis and a generally circular transverse cross section; and   a core having a weight of about 5 ounces,   wherein the longitudinal perimeter is between about 7 inches and 11 inches.   
   
   
       12 . The ball as claimed  claim 11 , wherein the core is solid. 
   
   
       13 . The ball as claimed in  claim 11 , wherein the longitudinal perimeter is about 9. 
   
   
       14 . The ball as claimed in  claim 11 , wherein the core of the ball is selected group consisting of plastic, cork, rubber, and a combination thereof. 
   
   
       15 . The ball as claimed in  claim 11 , further comprising an outer core. 
   
   
       16 . The ball as claimed in  claim 14 , wherein the core is in the center of the body. 
   
   
       17 . The ball as claimed in  claim 15 , wherein the body is covered with two pieces of leather that are stitched together using 108 stitches of thread. 
   
   
       18 . The ball as claimed in  claim 11 , wherein the ball has a cross section substantially similar to that of a regulation baseball.
