Man-to-man defence — also called one-on-one defence — is netball's most direct defensive structure: each defender takes one opponent and stays responsible for them wherever they go on court. It's built on the individual skill of marking, applied by the whole team at once.

Who marks whom

Man-to-man match-ups across the court A full court. The team with the ball is shown filled and the defending team outlined, each defender beside the opponent they mark. At the defending end, the Goal Keeper marks the Goal Shooter, the Goal Defence marks the Goal Attack and the Wing Defence marks the Wing Attack. In the centre third, Centre marks Centre. At the other end, the Wing Attack marks the Wing Defence, the Goal Attack marks the Goal Defence and the Goal Shooter marks the Goal Keeper.

Who marks whom. Outlined circles are the defending team; filled circles are the team with the ball. Each defender takes the opponent whose position mirrors theirs: GK on GS, GD on GA, WD on WA and C on C — and at the other end, WA on WD, GA on GD and GS on GK.

Netball's positions make the match-ups natural. Each defender's playing areas mirror an attacker's, and World Netball's description of the positions spells out the pairings: the Wing Defence prevents the Wing Attack feeding from the circle edge, the Goal Defence works to stop the Goal Attack scoring, and the Goal Keeper the Goal Shooter. Centre marks Centre, and at the other end the attacking positions mark their opposites when the ball is lost.

Because offside limits where every position can go, each match-up only ever happens within the thirds both players are allowed in.

How it works

World Netball's coaching material describes one-on-one defending like this: the defender tries to stop their opponent receiving the ball by tight marking, and the aim is to dictate the spaces the attacker can go into and force a turnover or a held ball. The team is trying to force the opposition into errors.

Three things make it work:

  • Vision. Each defender needs to see their opponent, the ball and the players around them.
  • Forcing play the same way. World Netball's guidance on defending through the court is for the whole team to force attackers away from the ball and towards the sideline, working together to restrict the space available.
  • Communication. Attackers will swap positions and use decoy runs to pull defenders around. Defenders need to call it.

Semi-loose marking

A variation in the manual: still one-on-one, but the defender stands slightly off their opponent, giving the passer a false sense of security. The passer thinks the attacker is free, throws — and the defender moves to intercept. Timing is everything: commit too soon and the defender is easily beaten, or the pass isn't made.

Strengths and weaknesses

Strengths Weaknesses
Clear responsibility: every player knows exactly who they're marking Reactive: World Netball notes you're following and anticipating your opponent rather than creating chances
Puts your best defenders on their most dangerous attackers Physically demanding: probably the hardest way to defend, needing very good fitness
Constant pressure all over the court, forcing errors Decoy runs and position swaps can pull defenders out of shape without good communication

Man-to-man versus zone

In a zone defence, players defend areas of the court rather than individual opponents, filling the spaces the attack wants to pass into to set up interceptions. Man-to-man tends to suit teams with strong individual defenders who can win their match-ups; zone relies on total teamwork, and suits teams wanting to create interceptions rather than react. Many teams use both within a match, and double defence is a way to put two defenders on one dangerous attacker for a period.

Beginner version

Man-to-man is usually the simpler structure to teach first, because each player's job is completely clear. Start with marking technique — quick, short steps, on the ball side, arms in when the opponent doesn't have the ball — then the team habit of forcing play towards the sideline (see how to mark and the one-on-one shadow defending drill).

Advanced variations

  • Switching match-ups in response to fatigue or a particular threat.
  • Mixing in semi-loose marking on players who are likely to receive long or diagonal passes, to set up interceptions.
  • Centre-pass defence. World Netball's coaching cards describe defending set centre-pass patterns — for example, the Centre and Wing Defence double-defending the Wing Attack while the Goal Defence forces the Goal Attack towards the sideline. See centre pass tactics.

Coaching points

  • Agree the match-ups before the match, and how players will call a switch.
  • Work on fitness: World Netball calls one-on-one marking probably the most physically demanding way to defend.
  • Teach players to mark on the ball side and force leads towards the sideline.

Common mistakes

  • Losing an opponent who moves into a teammate's area instead of following them.
  • No communication when attackers swap positions to confuse the match-ups.
  • Ball-watching, so the opponent gets free off the ball.
  • Every defender reacting independently instead of the team forcing play the same way.
