It is actually called the wing, and they are the outer positions on the forward line, the left wing and right wing are what they are called. In Field Hockey, they always stay to the side so you player can give you a breakaway. This is when everyone is clumped on one side of the field, they pass you the ball so no one on the other team is blocking you. When you are by the other teams goal cage, the wing stands at the post, or the side of the goal, so when someone passes them the ball, they can just easily hit it in.
