In the diagram below, place 9 balls along the side-pockets then place the cue ball in the lower or upper right side of the table at level A or line A for a straight in shot at the first ball.
The objective of this drill is to have consistency on a straight-in shot with a minimal draw applied. Upon pocketing the first ball, try a straight or semi straight-in position on any of the other balls & pocket each in either corner pockets only in the left side of the table. To raise the difficulty, try doing the same routine but positioning the cue ball at level B and try to draw the cue ball along that line. i find this drill setup simple but very challenging since you also practice a control on the cue ball from a draw stroke.
Once you master this drill, you will be so confident to execute a draw from a straight-in shot for a positional play.
