Setter, opposite, central, spiker. Anyone watching a volleyball match hears these names repeated as if they were official categories, comparable to the goalkeeper in football. In the international rules of the game however, they never appear. The rules mention only six numbered positions, the difference between first and second line and a single truly codified role, which is the free.
All the others are the result of coaches’ strategies or decisions and they arise from a very rigid constraint, the obligation to rotate clockwise, and from a freedom that the regulation allows in the space of a fraction of a second. Between the women’s European Championships that have just concluded and the men’s European Championships that have just begun, volleyball returns to television for a month, and it is a good time to understand where the roles we hear about really come from.
What does each of the 5 roles do: setter, opposite, central, spiker and libero
The setter, the role of Simone Giannelli and Alessia Orro
It’s the player who touches the second ball in almost every action and who chooses, in a few moments, who to entrust the attack to. In the three rotations in which he is in the second row he must run towards the net to be able to serve, but he can only start after the contact of the serve, because before that moment he is still tied to his rotation position. Simone Giannelli and Alessia Orro play this role in blue, and it is no coincidence that they are the two players who touch the balls more than anyone else.
The opposite, the role of Yuri Romanò and Paola Egonu
He stands diagonally with the setter, so he finds himself at the net precisely in the rotations in which the setter plays behind. He is the offensive terminal of the team and attacks both from position 2 both as a second line, with very high playing volumes. In the most widespread scheme today, he remains outside of the reception, which is entrusted to the two spikers and the libero, so as to be able to concentrate only on attack and blocking. Yuri Romanò and Paola Egonu (who scores a point with a dunk in the video below) are the opposite starters of the Italian national team.
The central defenders, the role of Gianluca Galassi and Anna Danesi
They attack the center with very rapid trajectories and are the first responsible for the wallso with each opponent’s action they must move along the net to double the attacker chosen by the opposing setter. They remain at the front in three out of six rotations and, when they rotate behind, they almost always come replaced by the freeso a center back is actually on the pitch for about half of the rallies. They are typically the tallest players on the team, as well as the ones who accumulate the most high-intensity jumps. In blue the role is that of Gianluca Galassi, Giovanni Sanguinetti, Anna Danesi and Sarah Fahr.
The spikers, the role of Alessandro Michieletto and Myriam Sylla
They are the more complete playersbecause they receive the opponent’s serve in bagher, attack from position 4, block when they are at the net and defend when they are behind. Thanks to the diagonal, one of the two is always in front and the other is always behind, which guarantees the team both a band attacker and a reliable receiver at all times. Alessandro Michieletto, Daniele Lavia and Myriam Sylla are Italian examples, but recently we saw Julio Velasco deploy Ekaterina Antropova in this role, with an opposite role, to be able to send her on the field together with Paola Egonu.
The libero, the only role written in the rules
Introduced in 1998 among the changes that rewrote the game together with the new scoring system, the libero is the only role that the regulation defines and regulate explicitly. The rules describe him as a specialized defensive player and allow him unlimited substitutions that are not counted among substitutions, but prohibit him from serving, blocking or even attempting a block and finishing an attack when the ball is entirely higher than the edge of the net. Furthermore, no teammate can attack from above the net a ball that the libero has dribbled into the frontcourt. In blue, the role belongs to Fabio Balaso among the men, while among the women the reference in recent years has been Monica De Gennaro, who left the national team after winning the 2025 World Cup.
Six numbered positions and the obligation to rotate
On the pitch there are always six players per team, arranged in two rows of three. Each position has a fixed number: the three closest to the net occupy the 4th on the left, the 3rd in the center and the 2nd on the right. The three behind occupy the 5th on the left, the 6th in the center and the 1st on the right, with a numbering that seems disorganized, but which instead follows the direction of rotation. When the receiving team wins a rally they win the serve, and at that moment everyone moves one place clockwise. Whoever was in position 2 ends up in position 1 and goes to serve, whoever was in 1 moves to 6, whoever was in 6 moves to 5, and so on until the round is closed.
No one can therefore settle in the area they prefer and in the space of six serves won each player passes through all six positions. The difference between first and second line it weighs a lot: only the three front row players can block and attack from above the edge of the net. The back three cannot block, and to hit a ball higher than the net they must come from behind the 3 meter line.
But there is one loophole which allows you to move more or less freely on the court: the regulation checks the deployment only at the moment in which the serve is hit, and from that moment on each player is free to move wherever he prefers, so much so that a moment after the serve the team has already recomposed in a completely different arrangement from the one just checked by the referee. However, this freedom only concerns the area of the field you occupy, not the rights you have. The first and second lines those fixed remain at the moment of service for the entire duration of the rally, so whoever started behind continues to be unable to block and, if he wants to attack a ball higher than the net, he must still come from behind the 3 meter line, even if in the meantime he has run up to the net.
It is into this margin, very wide in terms of movements and zero in terms of permits, that it has slipped in the entire specialization of modern volleyballbecause each player can go and occupy the area in which he performs best without changing the function he has in the action. From 2025 the constraint has become even lighter, given that the rotation order must be respected only by the receiving team, while the server can place himself freely in his own half of the pitch while respecting the constraints between the first and second lines.
Because the roles line up diagonally
If each player is forced to pass through all six positions, how can you guarantee that there is always someone in front of the net ready to block and an attacker to entrust the ball to? The solution is geometric and concerns the way the team is deployed at the start of each set.
Positions 1 and 4, 2 and 5, 3 and 6 are separated by three rotation stepsthat is, by half a turn, e they form three diagonals. Since the first line is composed of positions 2, 3 and 4 and the second of positions 5, 6 and 1, each diagonal always has an extreme in front and one behind. By lining up the two players playing the same role along the same diagonal, a coach automatically achieves that one of the two is at the net in every rotation. Consequently, the two central players occupy one diagonal, the two spikers another, and the third is reserved for the setter and the player on the opposite side, who for this reason is called “opposite”. The result is that in each of the six rotations in front of the net there is always a center back, a spiker and one between the setter and the opposite player.
How to recognize roles while watching a match
The easiest way to orient yourself is to look at the pitch twice, before and after the referee’s whistle. The moment the serve starts, the arrangement you see corresponds to the rotation order and only serves to avoid the positional fault. A second later the same team has already recomposed according to roles, with the setter running towards the net, the centre-back occupying the centre, the spiker spreading to the left, the opposite player taking the right wing and the libero manning the back.
It is in that short interval that volleyball stops being a game with six interchangeable positions and becomes the sport of specialists who fill the arenas. The rules continue to call everyone simply first or second line players, but the geometry of the rotation, combined with the freedom to move as soon as the ball is in play, has ended up generating roles so defined that today no one would be able to describe a match without naming them.
