To adapt to an opponent who employs a wide variety of serves, it's essential to focus on enhancing your reading of their cues and patterns. Start by observing their toss height, spin, and stance to anticipate the type of serve they might deploy. Develop a flexible reaction strategy, emphasizing quick footwork to position yourself appropriately for both fast and spin-heavy serves. Additionally, practice returning different types of serves during training to build confidence and improve consistency. Staying mentally engaged and ready for quick adjustments can also help you maintain focus and react effectively, allowing you to neutralize their serving advantage and regain control in the point.
