What Is The Defensive Specialist (DS) In Volleyball?

The defensive specialist, DS for short, is one of the players on the court that is consistent with passing, digging, and sometimes serving in the back row. Their job is to be reliable and get the ball up to the setter at whatever cost. They scramble for the ball making impossible saves. They usually substitute in for a front row player and only play in the back row.   

The DS will usually substitute into the game for a front row player when they get to the back row. They will sometimes go in to serve and then rotate just in the back row before coming back out for the front row player. When coming into the game, they must be focused and ready to pass or dig. 

As they rotate through the back row, they will often switch with other back row players to play the sides. The libero covers the back court while the DS covers the middle court. There is usually a hitter or setter that help cover on serve receive, so there are three players in the back row at those times. But, when the setter or hitter are playing the front row, the DS and libero share the back row.

Before this position got its name, the player was just called a back row player. They would play across the back row and substitute out for a front row player when they got to the front row. There wouldn’t be much switching in the back row until this position and the libero position started. Adding this position has made the game of volleyball more exciting because the player can concentrate on specializing in defense and make great plays.

Responsibilities And Skills Of The Defensive Specialist

Responsibilities And Skills Of The Defensive Specialist

There are many responsibilities and skills of the defensive specialist in volleyball. In this section, we will discuss some of those responsibilities and skills.


There are five important responsibilities that the DS performs that is helpful to their team’s success.

  • Serve receive
  • Digging
  • Passing
  • Covering players
  • Teamwork

Serve Receive

Being able to pass the ball well on serve receive is essential for a defensive specialist. Getting aced on or shanking it for their teammates to scramble after is not fun. If the serves are difficult to receive, it is the responsibility of the DS to adjust to receive the next serve successfully. 

It is important for the DS to practice receiving serves with the right techniques of passing. They need to work well with the libero in the back row communicating with each other as to what area they each need to cover. The DS usually covers the shorter balls that come over the net while the libero covers the back.  


The DS is often responsible for digging the ball when it comes over the net on a hit from the opposing team. The DS needs to be able to anticipate where the ball is going on the court by reading the hitter. After they know where the ball is going, they need to get into position quickly and stay low to pass the ball up to the setter. They should always remember to face where they want the ball to be passed. There is a lot to remember when digging, so practicing the right techniques often is necessary to be a successful defensive specialist.


Passing is the main responsibility of the defensive specialist. They need to have good ball control and focus when passing the volleyball. To have good ball control, they need to use techniques such as flat platform with their arms, good body position, knees bent, and good posture. 

The defensive specialist works closely with the libero, so it is important to use good communication skills with one another. If these two positions can get into a rhythm together in the back row, they will have great success. Usually, these two players are talking with each other on what areas to cover as well as giving one another encouragement.

Covering Players

Getting into position to cover other players is another responsibility of the defensive specialist. When the front row players are hitting or blocking, the DS should move up to cover the ball in case it’s blocked or returned quickly back over the net. If the DS is reading the players on the opposite of the net, they can anticipate where they need to cover. 

For example, if the ball is set to the outside hitter, the DS may notice by the way they approach the ball if the ball is going to go downline, short, or cross court. The DS can then call out to the other players what they notice. This helps the entire team play good defense.


Teamwork is important for any position in volleyball, but for the defensive specialist it is especially important. If a DS has a good relationship with their teammates, it will help their teammates trust them more on the court. The DS can often see what is coming from the other side of the net, so communicating to the other players what to expect is important. Another way to gain trust is to move quickly and make every effort to get to the ball. The DS must be willing to do whatever they can to keep the ball in the air. This will help their team know they are doing their part of teamwork.

Drills For Defensive Specialists

Drills For Defensive Specialists

Defensive specialists can become better at their position by practicing some drills. Drills will help them become more consistent with their passing, digging, and court coverage. Below are three drills that will help defensive specialists improve their game.

Two-Ball Defensive Pursuit Drill

In this drill, two players split the court and the coach stands at the net. The coach hits, tips, or throws the ball into the court. The players need to get the ball back to the coach in two contacts. The players stay on the court until they reach a set number of completions. If a ball touches the ground without the players making effort, they lose all their completions. 

Variation: There is not out of bounds and the ball can be entered anywhere.

Partner Dig

This drill is a simple one but allows two players to help each other with their digging ability. The players stand far enough apart to allow for one player to hit, tip, or throw the ball toward the other player. The coach or players decide on how many balls each player will dig when it’s their turn. When all of that is decided, one player hits, tips, or throws the ball at the other player that many times. When finished, the players switch. 

Important: Be sure to give each other challenging balls to return.

Knockout Digging Drill

In this drill you will need to outline a small box on the court with a large box around it. Line up the team to receive the ball. The coach hits, tips, or throws the ball to the first player. After the player digs the ball, they try to catch their own dig. If they catch the ball in the little box, that is the best, then big box, then anywhere.

For example, if the first player catches their ball in the big box, but the second player behind them catches their ball in the little box, the first player is out. This continues through the line until one player is left.

Important: If the players catch the ball in the same area, they both stay in the game.
