Provost Marshal Enoch Crowder issues a “work-or-fight” order, originally setting July 1 as the deadline for players to enter needed war workforce or face induction into military service. Secretary of War Newton D. Baker, who ignores Woodrow Wilson’s letter stating that the President saw “no necessity” for curtailing major-league play, does permit the major leaguers to continue to play through Labor Day, allowing the completion of the shortened season and the World Series with the teams’ rosters staying intact.

The Senators play the District’s first Sunday game, beating Cleveland in a dramatic, 1-0 twelve-inning contest in front of the largest crowd in the history of American League Park. The 17,000 spectators packed into the Washington D.C. ballpark include 2,000 soldiers, who are guests of the team, several U.S. Senators, and a Justice from the Supreme Court.

In a game that takes only 2 hours and 47 minutes to play, Senators’ legend Walter Johnson goes the distance in an 18-inning contest, defeating Larry Williams, who also tosses a complete game, and the White Sox at Comiskey Park, 1-0. Eddie Ainsworth, who advances to third base on the ‘Big Train’s’ single, scores the winning run on a wild pitch.
