It’s my understanding that the National League is the only organized baseball league in the US that does not use the designated hitter. The American League does, of course, and I guess all the minor leagues do also. NCAA baseball also uses it. Are there any other leagues besides the NL that do not use the DH? Does high school baseball use it? (I know high school baseball isn’t really a “league.”) Little League? The Mexican League? Either of the Japanese leagues? Any other leagues I don’t know about?
Just wondering how widespread the use of the DH is, especially outside the US.
