<P> After Griffith 's death in 1955 , his nephew and adopted son Calvin took over the team presidency . Calvin sold Griffith Stadium to the city of Washington and leased it back leading to speculation that the team was planning to move as the Boston Braves , St. Louis Browns and Philadelphia Athletics had all done in the early 1950s . By 1957 , after an early flirtation with San Francisco ( where the New York Giants would eventually move after that season ended ) , Griffith began courting Minneapolis -- St. Paul , a prolonged process that resulted in his rejecting the Twin Cities ' first offer before agreeing to relocate . The American League opposed the move at first , but in 1960 a deal was reached : The Senators would move and would be replaced with an expansion Senators team for 1961 . Thus , the old Washington Senators became the Minnesota Twins . </P>
