886-1889 Washington Nationals (National League)
While not the first Washington Nationals, this is the first one to have lasted more than a year. They had a few good players, including an alleged innovator and a future Hall of Fame manager, and played at Swampoodle Grounds. Apparently, Swampoodle was the old name for the area around Union Station, and the Stadium was located on the spot where Union Station is now sitting. Reader and twitterer @MorseBeard did some research on the Swampoodle grounds, and had some good stuff to add. The next paragraph is all from… his research:
The stadium was called Capitol Park, but contemporary sources referred to it as the Swampoodle Grounds. After doing his own research years ago, he found that  “Capitol Park” had been located at the corner of North Capitol St and Mass Avenue, NE, with home plate situated near that corner, with the field fanning out northeasterly from there. Here is a link showing that spot. That’s the Old Post Office building now (you know, with the Capital City Brewing attached) and while it’s very close to Union Station, it is actually about a block over. His location is more descriptive anyway, indicating where home plate is and all. He also noted that ownership actually preferred to call the team the Statesmen, although Nationals was used as well.
The stadium did have some historic moments – Hall of Fame pitcher Pud Galvin won his 300th game there. As a sidenote, here’s an interesting story on Pud Galvin and steroids that were basically testosterone drained directly from a monkey’s… um… testosterone-makers.
1891-1899 Washington Senators (National League)
This team started in the final year of the American Association, and were known as the Washington Statesmen (hey, it beats “Wizards”) but when the league folded they continued on in the National League. Clearly those baseball forefathers saw the wisdom of playing in DC.

Eventually eliminated by contraction of the NL in 1900, they were resuscitated as the Senators in the 1901 AL. They played in Boundary Field, located at the corner of Georgia Ave and W St NW. Eventually it was renamed National Field, burned down, and Griffith Park went up in its place. Major League baseball was played at the location until 1960 1961, and today it is the site of Howard University. The best thing that happened on this field, as far as we’ve seen, is the following story taken from www.projectballpark.org (same place this picture was nabbed):
