As can be seen below parity is all the rage in Major League Baseball these days outside of a handful of California-based franchises. San Diego is covering all their bases as they currently have the best run prevention and worst run production in the sport (and yes, the plot takes park factor into consideration).
The reasons behind a lack of disparity among so many teams are many, but a big one is the seemingly like-minded approach a lot of front offices have developed with the saber metric revolution of the last 15-20 years. Baseball decision makers are more educated overall than they have ever been. In the short-term, and perhaps the long-term as well, this opens the door for small market teams to achieve greater things on the field with more regularity due to the increasing accessibility of vital player information.
