<Li> Liberos are defensive players who are responsible for receiving the attack or serve . They are usually the players on the court with the quickest reaction time and best passing skills . Libero means' free' in Italian--they receive this name as they have the ability to substitute for any other player on the court during each play . They do not necessarily need to be tall, as they never play at the net, which allows shorter players with strong passing and defensive skills to excel in the position and play an important role in the team's success . A player designated as a libero for a match may not play other roles during that match . Liberos wear a different color jersey than their teammates . </Li> <Li> Middle blockers or Middle hitters are players that can perform very fast attacks that usually take place near the setter . They are specialized in blocking, since they must attempt to stop equally fast plays from their opponents and then quickly set up a double block at the sides of the court . In non-beginners play, every team will have two middle hitters . </Li> <Li> Outside hitters or Left side hitters attack from near the left antenna . The outside hitter is usually the most consistent hitter on the team and gets the most sets . Inaccurate first passes usually result in a set to the outside hitter rather than middle or opposite . Since most sets to the outside are high, the outside hitter may take a longer approach, always starting from outside the court sideline . In non-beginners play, there are again two outside hitters on every team in every match . </Li> <Li> Opposite hitters or Right - side hitters carry the defensive workload for a volleyball team in the front row . Their primary responsibilities are to put up a well formed block against the opponents' Outside Hitters and serve as a backup setter . Sets to the opposite usually go to the right side of the antennae . </Li>
