A baseball, softball or the like includes a ball core and a plurality of carcass panels attaching on the outer surface of the ball core. Each of the carcass panels, which is cut into a predetermined shape, has a main portion and an edge portion formed along a peripheral edge of the main portion, wherein each of the carcass panels is attached on the outer surface of the ball core without stitching with other the carcass panels at a position that the carcass panels are attached in an edge-to-edge manner, such that the carcass panels form an outer shell at the ball core in a thread-less manner.
