Interleague play existed for two reasons: Money and to set up Yankees-Mets in games that mattered. With those teams now having met in a World Series (and the Yankees ending all doubt by beating the Mutts decisively), it is meaningless except for money, which is why baseball won't do the right thing and end this abomination.
We already had interleague play. It was called the World Series. I may be a political liberal, but in baseball, segregation of the leagues was good.
As for the DH, I'd rather see David Ortiz play a position than see 99 percent of all pitchers come to bat. Every other league on Earth except the NL and one of the Japanese leagues uses the DH. Wake up and join the 20th Century, NL. And don't give me "nine men on a team." It's 25 men on a team, nine at a time.
I'd prefer to go to four Divisions a league, with only Division Champions making it. Teams are listed here by alphabetical order:
AL East: Baltimore, Boston, N.Y. Yankees, Toronto.
AL South: Kansas City, Nashville (better a baseball team than hockey), Tampa Bay, Texas.
AL Central: Chicago White Sox, Cleveland, Detroit, Minnesota.
AL West: Anaheim, Oakland, Salt Lake City (probably would be named "Utah"), Seattle.
NL East: N.Y. Mets, Philadelphia, Pittsburgh, Washington.
NL South: Atlanta, Cincinnati, Florida, Houston.
NL Central: Chicago Cubs, Colorado, Milwaukee, St. Louis.
NL West: Arizona, Los Angeles, San Diego, San Francisco.
The only tricky part is Denver, Colorado being in the NL Central, but it's the only way short of moving a team from one league to the other. I almost moved Arizona to the AL, but that would've bumped one of the expansion teams, and I couldn't think of a team east of the Rockies, other than a growing area like Nashville, where it would work. Not even Buffalo and Louisville, which are actually shrinking.
Yes, expansion to 32 teams. Don't tell me "the talent pool isn't there." It is. We're getting players from all over the world now. You think the pitching stinks now? Raise the mound from its current 10 to 12 inches. It won't be 15 like it was until 1968, but it will improve things, and maybe it'll help pitchers to the point where we can even go back to four-man rotations.
