ABSTRACT:
A durable, composite safety baseball or softball for practice or training purposes having a dual layer core comprised of an inner core of closed cell urethane and an outer core layer of relatively open cell urethane and covered with an outer cover of real or simulated leather which is softer than a conventional game ball and is thus less injurious to players and spectators. The ball is harder than prior practice balls and has payability characteristics substantially the same as conventional game balls when hit, thrown or caught.
