Wow.  Traditionally, the highest SO rate is for RL, although the most prominent such batter does not fit that description: Ricky Henderson.  Next worst is BL, the other group with few batters.  The lowest SO rate is for LR; Ted Williams does fit.

In recent seasons the three main groups (RR, LR, LL) are pretty even.
