Abstract
Abstract The invention concerns a partially inflexible device which may be worn as a glove by one attempting to increase his glove/hand reaction time proficiency in the baseball skills of catching, fielding and catch/throw agility. It also may be used by an instructor or coach in demonstrating or teaching those skills to players of any skill level. The glove has the palm portion thereof made inflexible whereby a user cannot flex the palm to catch a ball by squeezing it with his glove hand. Instead, the user is forced to use his free hand to trap a ball between the inflexible palm of the glove and the free hand. The inflexible palm portion of the glove can be integrally formed with the glove; it can be an insert, permanently secured into a pocket of the glove; or it can be an insert which can be easily inserted into and removed from a pocket of the glove.
