Well my mate was a crap batsman who became an openner in our team. He told me he just steps towards the ball if a pacemen. If a spinner (especially leggy) he doesn't let it turn so he either charges or pretends to so he can play the pull. Also, he used a small golf ball, tied a string around it, put it on a hanger and used a stump to practice his drives. Mind you he stole the idea from the great Don Bradman.
