The National League of course has the pitchers hit. Due to this, the leagues have evolved into different styles of baseball. The American League has more raw power and the National League uses more of what is called "small ball." Small ball may include stealing bases more, bunting more, and using more hit and run situations.
When I first heard that the owners approved a plan for interleague play, about 10 years ago, I was somewhat excited. I was thinking about the times when I lived in Western Pennsylvania and wasn't able to see the Yankees play the Pittsburgh Pirates, and how it would be neat to experience that. I thought also of the regional rivalries...specifically the Yankees and Mets, the Cubs and White Sox, etc. However, what has failed to happen is that new rivalries have not developed. Who care is the Florida Marlins play the Tampa Bay Devil Rays, or Cleveland Indians vs Pittsburgh Pirates? Cleveland and Pittsburgh hate each other's football teams, but as far as baseball goes there is not much enthusiasm in regards to baseball.
If you have followed the last round of interleague play, the National League has been killed! The Boston Red Sox killed the New York Mets, and the Yankees are winning against the Mets tonight as I type this. It is 2-0 at the 7th Inning stretch. I heard on a radio show that a New York sports host was in Boston for the Red Sox/Mets series, and was asked by a fan to "bring the team from New York that CAN play next time!"
I would be interested in knowing what people think of this thing we call Interleague play.
