A seaming structure using in baseballs and softballs is disclosed. Two covers including a first cover and a second cover close a ball core. A first seaming wire seams the two covers by alternatively passing through the two covers. Each of two upper seaming wires is arranged at an upper edge of one respective cover and is confined by a surface of the cover and the first seaming wire. Two lower seaming wires are similarly arranged, but they are arranged below the two covers. Moreover, a diameter of the upper seaming wires is equal to, great than or smaller than that of the lower seaming wires.
