It screws up American League club rosters, gets pitchers hurt, waters down the value of the World Series, and makes a ton of money for the owners. Guess which aspect of interleague play wins out?
The Red Sox will embark on the long death march of National League contests tonight in Philly. David Oritz will likely play first base and Adrian Gonzalez will patrol right field—and we use the word 'patrol' advisedly. Somebody will get hurt in this idocy—you can take that to the bank. The only positive thing about this year's fiasco is that it's better than next year's. Then, there will be inter-league play somewhere every night—further taxing the resources of American League teams.
Of course, as we have said before, if we had a real Commissioner, he would tell National League owners that if they want interleague, they have to adopt the DH—period. That's the only way that this nuttiness can ever be fair.
