Boston Americans pitcher Jesse Tannehill notched a 3-0 victory over the White Sox on May 25, 1906, thus ending a 20-game losing streak for the Americans. The streak began with a 0-8 loss to the New York Highlanders on May 1, 1906 and included 19 losses at home. The Americans would end the 1906 season with a 49-105 record.

Shows how things change. In 1903 they win the World Series. In 1904 the win the AL pennant (no Series). By 190 they lose 20 in a row. Such an unpredictable game.

So true! And it happens so fast. From one year to the next, a team can look and perform so completely differently.
