The Houston Astros are moving to the AL in 2013 and Major League Baseball is reconfiguring the schedule as ar esult. Among the potential consequences of the changes, according to ESPN New York's Adam Rubin: natural interleague rivals will no longer be guaranteed home-and-home series. That includes series like Cubs-White Sox and Yankees-Mets.
With themoving to the American League West next season and the leagues becoming balanced at 15 teams apiece, natural rivals throughout baseball no longer will be guaranteed six games a season and home-and-home series, the sources said.
According to one of Rubin's sources, these rivalries would most likely be limited to one series in one ballpark most seasons, or perhaps two games at each ballpark. Either way, interleague rivals won't be seeing as much of each other as they had been.
