Offered is one of the most historically significant pieces of game used baseball memorabilia ever presented. This is a unique baseball that saw action in the decisive Game 6 of the 1918 World Series, a Series won by the Boston Red Sox in six games over the Chicago Cubs. Not only was the ball used in the final game of this noteworthy World Series, it has also been inscribed by the most accomplished player in the annals of the game - Babe Ruth.Ruth was a two-time 20-game-winning pitcher as he entered the 1918 season. He was one of the aces of an imposing Red Sox staff and, indeed, he performed like an ace in that year's World Series. Ruth posted victories in two games, winning the Series opener as well as Game 4, where his consecutive-innings scoreless streak in World Series play finally ended (at 29.2). Interestingly, Ruth started and pitched three World Series games in his career, allowing one run in his first inning of a 14-inning, 2-1 win in 1916, and two runs in his last inning of his second win in 1918. In between, Ruth twirled his record scoreless-innings streak, which was eventually broken by Whitey Ford ... five decades later.The 1918 World Series was memorably different from earlier contests for a number of reasons. It was the only World Series to be played entirely in the month of September, as participation in World War I necessarily brought about a shift in the nation's focus. The European hostilities inspired a governmental "Work or Fight" order in the U.S., a policy that required all "non-essential," able-bodied men to either join the war effort stateside or risk being sent to the front lines for combat. Baseball abbreviated its season (to end September 1), and received deadline extensions from the War Department in order to play the World Series.This particular World Series, won by the Red Sox, initiated an 86-year Championship drought that would not end until the club's dramatic 2004 Series victory.
