Coach Jerry Ticer dives into the specifics of positioning and shot placement for doubles tennis. He introduces Rule Number Two, focusing on the importance of positioning your feet inside the singles sideline to accurately hit deep targets that your opponent can't reach. He emphasizes the significance of hitting a target near the back service line to keep your opponent off balance. The lesson then progresses to Rule Number Three, which teaches players to adjust their target when they find themselves outside the singles sideline. In this case, the Side T, where the service box meets the sideline, becomes the new target, ensuring the ball remains out of reach. This lesson highlights the adaptability needed to navigate court positioning and optimize shot accuracy in doubles play.
