Being left-handed can be an advantage in sports. For example, southpaw pitchers are in high demand in baseball. But not if you are a catcher. I found this article in the NYT that claims we will never see another lefty catcher in the majors, although the reasons are somewhat unclear.
I know for a time that no lefty was allowed to box professionally. Don't know if that is still true.
Is there something sinister about this (pun intended)?
