(CNN)Finally, after 15 frustrating seasons, the Washington Nationals are going to the baseball mountaintop -- the World Series -- for the very first time.
Washington Nationals beat St. Louis Cardinals, finally make it into the World Series
The Nats beat the St. Louis Cardinals 7-4 on Tuesday night to wrap up a resounding four-game sweep and claim the title as National League champs.
Now the team will sit back and wait to see which American League team they'll face. The Astros beat the Yankees 4-1 in Game 3 at Yankee Stadium in New York Tuesday and lead the best-of-seven American League Championship Series two games to one. Game 4 is scheduled for Wednesday, weather permitting.
