Universal DH has been a long-time coming, particularly with the move to three five-team divisions within each league, necessitating in at least one inter-league series at all times. I'm not sure how often this scenario has played itself out, but imagine a contending team - say, the Twins - is in the hunt for another Wild Card slot, and their last series of the year is an away series against an NL team. That would mean they'd either have to bat without their DH in the line-up (for argument's sake, let's say it's still Nelson Cruz, and that he's had an amazing, MVP-caliber year) or they'd have to pull Max Kepler (again, argument's sake: he's played Gold Glove defense all year) to get Cruz's bat in the line-up, leaving a huge hole in the outfield. Not even mentioning that then the AL team is relying on getting some offense from pitchers who swing the bat 5-10 times a year at most. Some will argue that's where a manager's strengths in strategy come into play; I argue that it's handcuffing a team by taking away potentially the most important pieces that got them to this point in the season. You don't have that in any other sport. Peyton Manning doesn't get to the post-season only to be told "Over here quarterbacks have to kick their own extra points." Lebron James never has to adjust his approach because 1/5 of the season free throws must be made from half-court. And, because I believe in the comedy Rule of Threes, Zach Parise has never had to make the switch from hockey stick to cricket bat during a crucial late-season run. (For the record, this scenario won't happen to the Twins this year, as their last road-series again an NL team is vs. Milwaukee August 13-14.)
