With the Astros now in the AL, that make an odd number (15) of teams in each league, and as a result we have an interleague series each and every week.
Now, I am a traditionalist, I believe pitchers should bat, but I am also about change, and since the union will never back down from DH in the AL, it's time for the NL to adopt the DH rule, this way, the playing field is even (pardon the pun) when AL teams visit the NL parks in aforementioned interleague games.
