best option is to use subtle variation to make the batsman do what YOU want him to do, instead of what HE wants to do. if u cant beat the bat, stick the ball where you know he will hit the ball constantly, and stick a fielder there. the pressure will make him make a mistake 
this should work well with a good slower ball in the same area, so he attacks it as normal and mistimes it to your fielder.
