Here's the alignment. Only one team moved out of their usual spot, and that's the expansion Rays:
Division Alignment
NL East: New York Mets, Philadelphia Phillies, Montreal Expos/Washington Nationals, Atlanta Braves
NL Central: St. Louis Cardinals, Cincinnati Reds, Milwaukee Brewers, Houston Astros
NL West: Los Angeles Dodgers, San Francisco Giants, San Diego Padres, Tampa Bay Rays
AL East: New York Yankees, Boston Red Sox, Toronto Blue Jays, Baltimore Orioles
AL Central: Cleveland Indians, Minnesota Twins, Detroit Tigers, Kansas City Royals
AL West: Oakland Athletics, Seattle Mariners, Texas Rangers, Los Angeles Angels
Rationale: We have one extra American League team. As the expansion team, the Rays get shipped out west in the NL.
