In the first game of a doubleheader against the Philadelphia Athletics on October 1, 1921, the Yankees clinched their first ever AL pennant. That led to things getting pretty weird in the second game of the doubleheader.
With a trip to the World Series already locked up, the Yankees sent out a slightly weakened lineup in the second game of the day, but it still included some of the Yankees’ big names. Pitcher Waite Hoyte got the start despite the World Series being just four days out and him being the Yankees’ number two starter.
