A ball (100) having a foam core (110) with a channel recess (114) formed on its surface is enclosed by a cover assembly including a rubber channel assembly (120) in the shape of a spherical curve, such as a baseball curve, and fabric panels (132) that are fixed to the channel assembly. The channel assembly is configured to be inserted into the channel recess in the core. In an embodiment, a heat-activated adhesive substrate is disposed between the cover assembly and the core. In an embodiment, a launcher engages the channel assembly to aid in throwing the ball. In an embodiment, a removable insert (220) is insertable to be retained in the channel assembly.

1. A ball comprising: a foam core defining a deep and wide elongate channel along a surface of the foam core;a channel-shaped insert received into the elongate channel and completely overlying the elongate channel, wherein the channel-shaped insert comprises a rubber; anda fabric cover attached to the channel-shaped insert, and overlying portions of the foam core that are not covered by the channel-shaped insert such that the foam core is enclosed cooperatively by the channel-shaped insert and the fabric cover. 2. The ball of claim 1, wherein the channel-shaped insert defines a spherical curve. 3. The ball of claim 1, wherein the fabric cover comprises a plurality of woven panels. 4. The ball of claim 1, wherein the channel-shaped insert further comprises flanges, and the fabric cover is attached to the channel-shaped insert by stitching to the flanges. 5. The ball of claim 1, wherein the fabric cover is attached to the foam core with an adhesive. 6. The ball of claim 5, wherein the adhesive comprises a heat-activated adhesive substrate. 7. The ball of claim 1, wherein the channel-shaped insert defines a channel having a varying width. 8. The ball of claim 7, wherein the channel has a maximum width that is between 8% and 12% of a circumference of the ball and a minimum width that is between 4% and 8% of the circumference. 9. The ball of claim 1, wherein the channel-shaped insert has a textured surface that improves the gripping properties of the insert. 10. The ball of claim 1, wherein the foam core defines a center void. 11. The ball of claim 1, wherein the foam core has a density in the range of 1.4 pounds per cubic foot and 6.0 pounds per cubic foot. 12. The ball of claim 1, wherein the cover is a first color and the channel-shaped insert is a second color that is complementary to the first color. 13. The ball of claim 1, wherein the ball is generally in the shape of a prolate spheroid. 14. A ball and launcher comprising the ball of claim 1, and further comprising a launcher comprising a flexible handle portion and an elongate pliable member fixed to the handle portion and configured to releasably engage the channel-shaped insert. 15. The ball and launcher of claim 14, wherein the elongate pliable member comprises a strap, a lanyard, or a cord. 16. A ball and launcher attachment comprising the ball of claim 1, and further comprising a launcher attachment configured to be fixed to a flexible elongate member, the launcher attachment comprising a collar portion having a releasable attachment, and an elongate pliable member fixed to the collar portion and configured to releasably engage the channel-shaped insert. 17. The ball and launcher attachment of claim 16, wherein the elongate pliable member comprises a strap, a lanyard, or a cord. 18. A ball and separable insert comprising the ball of claim 1, and further comprising a separable insert that is sized and configured to be releasably retained in the channel-shaped insert, wherein the separable insert modifies the rolling characteristics of the ball. 19. A method for forming a ball having an elongate channel comprising: (a) forming a substantially spherical or prolate spheroidal core defining an elongate channel recess on its outer surface;(b) forming a cover assembly sized and configured to receive the core, the cover assembly comprising a rubber channel that is fixedly attached to a plurality of panels;(c) inserting the core into the cover assembly such that the rubber channel is disposed in the core channel recess; and(d) closing the cover assembly such that the core is fully enclosed by the cover assembly. 20. The method of claim 19, further comprising applying an adhesive to the core prior to inserting the core into the cover assembly. 21. The method of claim 19, further comprising: (e) forming a heat-activated adhesive substrate to overlie the core between the core and the cover assembly,(f) positioning the adhesive substrate between the core and the cover assembly, and(g) heating the adhesive substrate to activate the adhesive. 22. The method of claim 19, wherein the plurality of panels comprise fabric panels, and the cover assembly is assembled by stitching the fabric panels to the rubber channel. 23. The method of claim 19, wherein the elongate channel recess is in the shape of a spherical curve. 24. The method of claim 19, wherein the channel has a width that varies along the length of the channel.
