For both Major and affiliated Minor League players, the standard player contract calls for the club to “furnish two complete uniforms, exclusive of shoes.” At the time the clause was written, this meant the home whites and the road grays. Today, in practice clubs will furnish as many combos as they require the guys to wear, for Sundays and holidays and promotional dates. Pants are cut to order for individual players. Technically all uniform pieces remain club property; sometimes Minor League teams sell game-worn gear to fans. I presume that players who keep their jerseys after the season have the cost deducted from a paycheck at some point.
