I dont' think they get the Os every year. I think Toronto and Boston alternate between the Braves and the Phillies. The Mets get the NYY, the Rays get the Marlins, the Os get the Nats, and the other two eastern teams alternate. The Red Sox and Braves complained about always being matched up in the late 90s and early 00s when Philly was the worst of the 4 teams.
