98% of you grip the club too tight. The tighter you grip the golf club, the slower the club will roll over. The looser you grip it, the quicker the club will roll over and you will draw the ball.
Check your grip pressure before hitting a draw. If you're set up for a draw and aimed right, but grip the club too tight, you won't crossover and give the ball right to left spin and the ball will stay to the right.
