Correct Response: D. Encouraging student bowlers to use a grip that is comfortable and places no strain on the fingers, thumb, or hand helps establish the foundation for effective development of other bowling skills and reduces the risk of injury. Because there are a few variations that affect control, release, and power, students should develop a grip that provides them with the confidence and security suited to their experience and skill level. Once a comfortable, secure grip is established, students can work on a four- or five-step approach (B), and aiming and rolling a straight ball (C) or a hook ball (A).
