ABSTRACT:
A baseball or a softball includes two or more cover members engaged on the outer portion of a core and having an abutting peripheral portion. A pad is engaged between the core and the abutting peripheral portion of the two cover members and is stitched and secured to the abutting peripheral portion of the cover members by a thread. When the thread is tightened, a number of bulges may be formed along the abutting peripheral portion of the cover members. The thread may be engaged between and protected by the bulges from being easily worn out.
