It is the Washington Nationals because they are a new team that does not have a lot of experience.
The New York Yankees won 27 World Series titles, in 40 Appearances.
1. Best baseball team ever. 2. Team with the most championship ever won in any sport. 3. Holds record for most consecutive world series titles won. 5. 4. Team with the highest payroll in the MLB. 5. Team with the most playoff apearances. 6. Did I mention they are the best team ever in the MLB? Because they are.
Considering that the Yankees have 26 world titles and have been to at least 6 more I would see the New York Yankees.
