One of my favorite drills is not only good for practicing rail shots and position play it is also great for getting in stroke. Place the six object balls in the middle of each rail and slightly off the rail (1” to 2”).

Start with ball in hand and run the balls in numerical sequence, if you miss start over. As you become proficient at doing this exercise switch the balls around so that you are not always playing the same pattern. Another thing you can vary is the distance of the object balls from the rails. Try all the different possibilities.
