The 1927 New York Yankees season was the 25th season of the New York Yankees of the American League. The team finished with a record of 110–44–1, winning their fifth pennant and finishing 19 games ahead of the Philadelphia Athletics and were tied for first or better for the whole season.^[1] New York was managed by Miller Huggins, and played at Yankee Stadium. They won the 1927 World Series, sweeping the Pittsburgh Pirates. This Yankees team was known for its feared lineup, which was nicknamed "Murderers' Row", and is widely considered to be the greatest baseball team in MLB history.^[2][3][4]

The Yankees' 110 victories broke the previous American League mark of 105 (set by the 1912 Boston Red Sox) and would stand as the American League single-season record until it was broken by the Cleveland Indians in 1954. But counting their World Series sweep, the 1927 Yankees had a total record of 114–44 --- which is still the all-time highest single-season winning percentage (.721) in American League history. The 1998 Yankees, who also won their World Series in a sweep, are second with a full-season mark of 125-50 (.714).^{[citation needed]}

This was the first year the Yankees acknowledged their team nickname on their uniforms, albeit their road uniforms. Their home uniforms remained free of any kind of logo except for the "NY" on their caps.

The roster included nine future Hall of Famers: Pitchers Herb Pennock and Waite Hoyt, Infielders Lou Gehrig and Tony Lazzeri, outfielders Babe Ruth and Earle Combs, Manager Miller Huggins, Team President Ed Barrow and Owner Colonel Jacob Ruppert.

Since a voter could select only one player per team, two good candidates from the same team could find their votes split and both of their chances of winning hurt. In addition, the clause prohibiting repeat winners led to unusual results like Babe Ruth's 1927 (one of the greatest offensive seasons of all time) not being eligible for the award. As The New York Times wrote in 1925, "[T]he purpose, of course, is to pass the honor around, but the effect is to pass an empty honor around."^[6]

In 2016, ESPN announced 1927: The Diary of Myles Thomas, part of a new genre of storytelling known as "real-time historical fiction."^[8] The core of the project is a historical novel in the form of a diary of Myles Thomas, written by Douglas Alden, complemented by a wealth of fact-based content from the season, all published along the same timeline as the events unfolded almost 90 years ago. Through Myles Thomas's diary entries, additional essays and real-time social-media components (including Twitter^[9]) "re-living" that famous Yankees season, the goal is to explore the rarefied nexus of baseball, jazz and Prohibition — defining elements of the remarkable world that existed in 1927. The diary runs the length of the full 1927 season, from April 13 through October 10, 1927.^[10]
