This new team adopted the old Senators name, but was (and still is) considered an expansion team since the Twins retained the old Senators’ records and history. The Senators and Angels began to fill their rosters with American League players in an expansion draft. The team played the 1961 season at old Griffith Stadium before moving to District of Columbia Stadium (now the Robert F. Kennedy Memorial Stadium). Ownership changed hands several times during the franchise’s stay in Washington and was often plagued by poor decision-making and planning. Owner Elwood Richard Quesada once wondered why he needed to pay players who didn’t belong in the majors and later agreed to a 10-year lease at D.C. Stadium a move that would come back to haunt the Senators. In 1963, Quesada sold his stake in the club and resigned. Washington stockbrokers James Johnston and James Lemon owned the team briefly, suffering massive financial losses. Johnson died in 1967 and Lemon sold the team a year later to hotel and trucking executive Bob Short, who outbid a group headed by Bob Hope. Short named himself general manager and hired Hall of Famer Ted Williams as manager. Although Williams had never coached or managed at any level of baseball, he seemed to light a spark under the once-moribund Senators. Williams kept them in contention for most of the season; their 86–76 record would be its only winning season in Washington.

Short was especially receptive to an offer brought up by Arlington, Texas mayor Tom Vandergriff, who had been trying to obtain a Major League sports team to play in the Metroplex for over a decade. Years earlier, Charles O. Finley, the owner of the Kansas City Athletics, sought to relocate his baseball team to Dallas, Texas, but the idea was rebuffed and ultimately declined by the other A.L. team owners.

Arlington’s hole card was Turnpike Stadium, a 10,000-seat park which had been built in 1965 to house the AA Dallas-Fort Worth Spurs of the Texas League. However, it had been built to Major League specifications and also located in a natural bowl, meaning only minor excavations would be necessary to expand the park to accommodate Major League crowds.

After Vandergriff offered a multimillion-dollar down payment, Short decided to make the move to Arlington. On September 21, 1971, by a vote of 10 to 2 (the Orioles’ Jerold Hoffberger and John Allyn of the Chicago White Sox registered the dissenting votes), American League owners granted approval to move the franchise to Arlington, Texas for the 1972 season.

Senators fans were livid. Enmity came to a head at the club’s last game in Washington. Thousands of fans simply walked in without paying after the security guards left early, swelling the paid attendance of 14,460 to around 25,000, while fans unfurled a banner reading “SHORT STINKS”. With the Senators leading 7–5 and two outs in the top of the ninth inning, several hundred youths stormed the field, raiding it for souvenirs. One man grabbed first base and ran off with it. With no security in sight and only three bases, umpire crew chief Jim Honochick forfeited the game to the New York Yankees.
