What Is a Penalty Corner? The Set Piece That Decides Hockey Matches

The award follows certain defensive offences inside the shooting circle or deliberate offences within the defending quarter. The ball is placed on the goal line ten metres from the near post and pushed out by an attacker, while the attacking team positions players at the top of the circle and the defending team places five players, generally including the goalkeeper, behind the goal line. Nobody may move until the ball is pushed, at which point the defenders charge out and the attackers have moments to control the ball, stop it at the top of the circle and execute their routine. The ball must leave the circle and be brought back in before a shot, and the shot itself is subject to rules about height and about the type of stroke used, which have changed repeatedly for safety reasons. The whole sequence takes a few seconds and is rehearsed exhaustively, with teams carrying specialists whose role is essentially this restart.

The routine assigns specific jobs and each is a specialisation in its own right:

• •The injector, who pushes the ball out along the ground with speed and accuracy, since a poor injection ruins everything that follows
• •The stopper or trapper, who controls the ball and places it precisely at the top of the circle in a fraction of a second
• •The striker, frequently a drag-flick specialist, who executes the shot and whose technique is the main attacking weapon
• •Deflectors positioned to redirect the shot, since a deflection changes the ball's direction after the goalkeeper has committed
• •The first runner among the defenders, who charges directly at the striker and takes the greatest physical risk
• •The goalkeeper and post defenders, who must cover the shot and the rebound simultaneously

The technique that transformed the set piece is the drag flick, in which the ball is dragged along the ground and flicked upward at high speed rather than struck. Its advantage is that the rules restricting the height of a first shot apply to hits and not to flicks, so a drag flick may be aimed high into the goal legally while a hit may not, and skilled exponents generate speeds comparable to a hit. It became dominant from the 1990s and changed the balance of the contest, since defenders charging out now face a shot they cannot block low. The response has been a series of rule adjustments and equipment changes, with defenders permitted protective masks and with restrictions on the shot revised repeatedly. The technique is physically demanding and hard to learn, which is why teams field specialists, and the best of them convert a substantial proportion of the corners a team wins, which makes winning corners a tactical objective in itself.

The set piece concentrates the sport's injury risk into a few seconds and the governing body has changed the rules repeatedly in response. Defenders run towards a ball that may be struck at high speed at close range, and serious facial and dental injuries have occurred, which led to protective masks being permitted and then normalised for the first runners. Height restrictions on shots exist for the same reason and their interaction with the drag flick has been the central difficulty, since a technique that is legal at height is far more dangerous to a charging defender. Proposals to abolish the penalty corner entirely, replacing it with a different restart, have been raised periodically and resisted because the set piece is central to the sport's identity and to its scoring. Variants have been trialled in shorter formats, including a one-on-one restart resembling a penalty shot in other sports, which is faster and more televisual and which has not displaced the original in the full game.

A restart from the goal line against five charging defenders produces a large share of the goals in field hockey, which is why teams carry specialists for each role in a rehearsed few seconds. The drag flick transformed it because height restrictions on a first shot apply to hits and not to flicks. That made the set piece more dangerous for charging defenders, which is why masks were permitted.
