Wikipedia
A baseball glove or mitt is a large leather glove worn by baseball players of the defending team which assist players in catching and fielding balls hit by a batter or thrown by a teammate.
By convention, the glove is described by the handedness of the intended wearer, rather than the hand on which the glove is worn: a glove that fits on the left hand—used by a right-handed thrower—is called a right-handed (RH) or "right-hand throw" (RHT) glove. Conversely, a left-handed glove (LH or LHT) is worn on the right hand, allowing the player to throw the ball with the left hand.
