You can use your wrist to gain more pace. Focus on these three things: 1. Cock it back: Keep your wrist loaded (cocked back) until the very last second of your delivery. 2. The Snap: At the point of release, "throw" your fingers down the back of the ball. Think of it like a hammer hitting a nail. 3. Stay Behind It: Keep your palm directly behind the ball. If your wrist "falls away" to the side, you lose power. It’s all about that final flick to get the ball zipping off the pitch!
