Batter/Pitcher Righty/Lefty splits beginning with 1950

Righty batter facing a righty pitcher is the base ... (in 1950) RvR - best at hitting home runs.  Lefty batters against righty pitchers sweep everything else.

It might be illustrative to add in strikeouts. Looking at the BABIP, it seem that most of the difference in BA is how often the batters put the ball in play.
