ABSTRACT:
A ridge-embedded softball or a ridge-embedded baseball in the present invention consists a spherical core, two cover pieces enclosing the core, and two threads to stitch the two pieces together. The feature of ridge-embedded softball or baseball in the present invention is that each cover piece has a stuffing strip embedded near the peripheral distal edge to create the ridges of the softball or baseball. Because the stuffing strips are firmly clamped between an outer skin and an inner fabric layer of the two cover pieces and can not squirm, the ridges are particularly and precisely defined on the softball or baseball to make the softball or baseball easily controlled during play.
