I use this drill every time I warm up. 

Super simple. Start with a short chip or pitch shot on the range. On your next shot, try to land the ball on top of the previous ball. It’ll roll out a little farther, then try to hit the 2nd ball with your 3rd shot, and so on. 

Each shot gets progressively longer, so every swing is unique, with a defined target. 

You’ll learn to control your distances and develop a great rhythm to your pitching game. 

By the way, it might be a good idea to tee the ball up for these shots at first. No need to dig them out of the dirt when you’re working on distance control and tempo.
