Possible World Series Match-ups

The teams in this year's MLB post-season allow for some interesting World Series match-ups. We could have the "I-70 series" between the Royals and the Cardinals, a rematch of the memorable 1985 Series. We could have a "freeway series" between the Angels and the Dodgers. We could have a "beltway series" between the Nationals and the Orioles. Had the Athletics not lost the wild card game, we could have had a "bay series" between the Giants and the Athletics. The remaining two teams out of the ten in the postseason are the Tigers and the Pirates, the latter having been eliminated by the Giants in the wild card game. A matchup between these two could have been called the "Rust Belt series".
