Monday will mark the beginning of the annual interleague series between the Washington Nationals and Baltimore Orioles. Starting with the first contest in Baltimore, the teams will play four games, with the first two slated for Oriole Park at Camden Yards before the matchup shifts to Nationals Park on Wednesday and Thursday.
The proximity between the two teams has led to an interleague staple since the Nationals arrived in D.C. in 2005, and has appealed to fans in both cities. Yet, after all these years, it still seems fair to question if the Orioles and Nationals are true rivals and, if so, to what extent?
