Now that interleague play is over I took a look at what MLB has for "natural rivalries". There are 11 such series, though, I'm not quite sure how San Diego - Seattle qualifies but it seems to. Three of the series finished 5-1 with the Indians winning only 1 game at home vs the Reds, Florida winning 1 game at Tampa, and the Padres winning 1 game at Seattle. Four of the series finished 4-2 but only the Twins won 2 of 3 in each stadium vs the Brewers. In the other 3 cases the Cardinals, the Giants, and the Yankees all dropped 3 in their own park before going on the road and taking 2 of 3 at the Royals, A's, and Mets, respectively. That leaves 4 series that split 3-3. The Astros - Rangers, Nationals - Orioles, and Dodgers - Angels all won 2 of 3 at their own facility while the Cubs and White Sox swept each other at home. Don't know what it all means other than the AL dominated the NL in this mini look as well as in the overall interleague play.
