A basketball includes a ball bladder, a plurality of cloth pieces, and a plurality of rubber patches. The ball bladder has an outer surface, which is formed with a rib network that divides the outer surface of the ball bladder into a plurality of areas and that has a top surface. Each of the areas has a periphery along which an annular recess is formed. The cloth pieces are adhered to and cover entirely the areas, respectively. Each of the cloth pieces has a periphery, which extends into the recess in the corresponding area and which abuts against the rib network. The rubber patches are adhered to and cover entirely outer surfaces of the cloth pieces, respectively. Each of the rubber patches has a periphery, which abuts against the rib network and which has an outer surface that is flush with the top surface of the rib network to define a groove network in an outer surface of the basketball along the rib network.
