Southpaw’s Revenge

Don't forget that a lefty at first also has the advantage of not having to cross his body with a tag on a pick off move.

The question that I have always wanted to see answered is this: Why is it so much more difficult for a lefty batter to face a lefty pitcher than a right-handed batter to face a right-handed pitcher? If it has to do with the angle of lefty's pitching motion, why can't that be duplicated by a right-handed pitcher?

Maybe it's just that batters are used to facing right-handed pitchers, which means the only logical conclusionis that I need to set up my 8 year old pitching machine so that it replicates a left-handed pitcher angle of flight. Money in the bank. Right?
