1998 MLB season changes:
 * 1998 expansion:
 * Arizona Diamondbacks are enfranchised; join the NL West
 * Tampa Bay Devil Rays are enfranchised; join the AL East

 * In order to primarily continue intraleague play, the Milwaukee Brewers transferred from AL Central to the NL Central so both leagues would have an even number of teams.
