The1957Washington Senators won 55 games and lost 99 in their 57th year in theAmerican League, and finished in eighth place, attracting 457,079 spectators toGriffith Stadium, last in the major leagues.Chuck Dressen began the year as theirmanager, but after the Senators dropped 16 of their first 20 games, Dressen was replaced byCookie Lavagetto on May 7. Lavagetto, a longtime aide to Dressen, went 51–83 for the rest of the year, but would remain at the club's helm into June 1961, its first season as theMinnesota Twins.

The 1957 Senators set anMLB record which still stands for the feweststolen bases by a team in a season, with only 13.^[1] Washingtonleft fielderRoy Sievers set a new team record with 42home runs to the lead the Junior Circuit, as he benefited from Griffith Stadium's shorter dimensions in left and left-center field, which had been implemented before the 1956 campaign.

The 1957 season also marked the first time that Washington's American League franchise had usedSenators as its official nickname since1904. For 52 years (1905–1956), the team called itself theNationals, withSenators as an unofficial, but widely used, secondary appellation. From 1957 on, headline writers and baseball journalists would continue to useNats as an accepted alternative name for both this Senators franchise and itsexpansion-era successor, theSenators of 1961–1971, until the "new Senators" relocated toDallas–Fort Worth after the1971 campaign. Since2005, theNationals name is the official identity of Washington'sNational League franchise formerly called theMontreal Expos.
