since the baseball glove was invented, they have grown to what they look like today. while catching in baseball was two handed, gloves grew to a size that made it easier to catch the ball in the webbing of the glove, and use the off-hand to keep it from falling out. a glove is worn on the non-dominant hand, leaving the dominant hand for throwing the ball; for example, a right-handed player would wear a glove on the left hand. by convention, the type of glove that fits on the left hand is called a "right-handed" or "rh" glove.
