When the two squads met last May in Washington D.C. the entire baseball world was watching after years of ignoring the matchup. The Nationals were rolling early, as many predicted, and the Orioles were playing some of the best baseball in the league to the surprise of almost everyone.
Now, after another full month of baseball, both teams are still among the league's best. The Orioles are 39-30 and in second place behind the New York Yankees, and the Nationals are in first place with a 40-27 record.
Both teams will look to finish interleague play strong by defeating their crosstown rival in this weekend's series.
