The 1899 Washington Senators baseball team finished the season with a 54–98 record, eleventh place in the National League. The 25 home runs that right fielder Buck Freeman recorded were truly remarkable by the standards of the time; his tally was not surpassed until Babe Ruth hit 29 home runs with the 1919 Boston Red Sox. When the NL contracted after the season, the Senators were disbanded. Owner J. Earl Wagner received $39,000 for his interest in the team.
