Interleague play, now in its 11th year, is back this weekend with some great natural rivalries such as the Mets-Yankees, Cubs-White Sox, A's-Giants, Angels-Dodgers, and, of course, Rockies-Royals and Phillies-Blue Jays. OK, not all the rivalries are great, or natural.
Despite its critics, interleague play is here to stay. Why? Because it makes money.
