In the previous post on top switch hitters I used averages for the census year numbers. I used these samples because I do not access to the annual data other than finding it for each individual year, highlighting, then copy/paste into a spreadsheet. I then need to organize it into a meaningful form. Obviously, this is tedious and time consuming.
Those census year numbers are volatile. Righty batters against righty pitchers seem to be considerably more effective in 2000 and 2010 for all but OBP. Here are the percentage differences from righty batter against lefty pitcher, the situation for which we have actual data for switch hitters most of whom are natural right handers.
The first column of percentages show the extra production the average MLB batter generally had batting lefty against a righty pitcher. The second percentage column is the dropoff by the average MLB batter batting righty against righty. Obviously this represents a general pattern that could be expected for switch hitters.
To reiterate, this is the base: righty batter against lefty pitcher. The percentages are the differences from that.
