A baseball and a method of instructing throwing a baseball is disclosed. The baseball has a seam, a first, preferably green, color zone placed on a first side of the ball, a second, preferably yellow color zone placed around a first circumference of the ball, and a third, preferably red, color zone placed on a second side of the ball. A pair of finger placement markings are carried on the first color zone. The baseball player is instructed to engage in a proper throwing motion, and the ball confirms by maintaining visual line of sight with the first color zone throughout, providing feedback of a correct throwing motion in which the ball is drawn. away from the target with the arm and hand placed in a correct position.

An object with a tactile outer layer includes, for example, a ball having an outer surface and a series of protrusions or spikes on the outer surface. The protrusion each appear as a tear-dropped shape mass that includes a base having a relatively flat bottom adhered to the outer surface of the ball and a narrow tip and/or curved tail extending away from the outer surface.

Manufacturing can be performed by mounting the object and utilizing injection arms that deposit elastomer globules on the object. The globules are deposited by pressure through a reservoir in the injection arm and the injection arms are then withdrawn to product the tail shape.

A youth baseball includes a core center and an outer surface that encircles the core center. The circumference of the outer surface is less than or equal to 8.375 inches. The weight of the youth baseball is less than or equal to 4.7 ounces.

A spiked ball includes an inflatable ball having an outer surface and a series of protrusions on the outer surface. The protrusion each appear as a tear-dropped shape mass that includes a base having a relatively flat bottom adhered to the outer surface and a narrow tip extending away from the outer surface. The narrow tip may also appear as a curved tale.

The spikes provide a unique tactile feel and a surface for gripping that is different than other balls. The spikes also cause the ball to contact or grab the ground to create a unique bounce.

The present invention is directed to a golf ball that includes at least a portion of its dimples having a plan shape defined by superposed curves. In addition, the present invention is directed to golf balls having improved aerodynamic performance due, at least in part, to the selection of the dimple plan shapes and resulting dimple patterns.

A game ball including a leather cover secured about a solid core, wherein the leather cover includes an inner surface contacting the solid core and an opposing outer surface and wherein the game ball is characterized by including polyacrylate particles dispersed on but not encased about the outer surface of the leather cover.

A molded game ball comprises an outer cover or surface having a mold line that mimics the seam of a conventional baseball or softball. The outer cover or surface may additionally include a stitch pattern that mimics the stitching of a conventional baseball or softball.

Provided is a golf ball having a surface divided by small circles. A surface of a sphere is divided by small circles to generate spherical polyhedrons in order to arrange dimples in the spherical polygons, instead of arranging dimples in spherical polyhedrons that are generated by dividing the surface of the sphere by great circles. According to one or more exemplary embodiments, a land surface of the golf ball, which is generated by arranging the dimples in the spherical polyhedrons, has a dimple area ratio higher than that of a spherical truncated icosahedron of which a surface is divided by great circles on which dimples are arranged. Therefore, a flight distance of the golf ball increases.
