Cotton Tierney

James Arthur Tierney (February 10, 1894 – April 18, 1953), nicknamed "Cotton", was an infielder in Major League Baseball (MLB). Tierney played in MLB from 1920 through 1925 for the Pittsburgh Pirates, Philadelphia Phillies, Boston Braves and Brooklyn Robins.

Tierney began his professional career in minor league baseball in 1912. The Pittsburgh Pirates acquired Tierney after he played for the Tulsa Oilers of the Class A Western League. Tierney and teammates Charley Grimm, Rabbit Maranville, and George Whitted, became known as the "Banjo Boys". He had a .345 batting average during the 1922 season, finishing fifth in the National League, and a .515 slugging percentage, good for fourth. He also finished fifth in triples with fourteen, tied with Rogers Hornsby. His performance earned him a $5,000 contract for the next season. However, the Pirates traded Tierney with Whitey Glazner and $50,000 to the Philadelphia Phillies for Lee Meadows and Johnny Rawlings in May 1923. In 1923, Tierney tied George Grantham for second in the NL in doubles with 36, training only Edd Roush, and finished seventh in home runs with 13.

On December 15, 1923, the Phillies traded Tierney to the Boston Braves for Hod Ford and Ray Powell. On February 4, 1925, the Braves traded Tierney to the Brooklyn Robins for Bernie Neis. Before the 1926 season, in what was considered "one of the most remarkable deals ever made between a major and a minor league club", the Robins traded Tierney to the Minneapolis Millers of the American Association with Ford, Dick Loftus, Bonnie Hollingsworth, and their choice of Del Bissonette, Babe Herman, and Chuck Corgan in order to acquire Johnny Butler.

Tierney managed the Pueblo Steelworkers of the Western League in 1929. He managed the Joplin Miners of the Class A Western Association in 1930.

Tierney returned to Kansas City, where he operated a bowling alley with Zack Wheat. He died in his home at the age of 59.

In 2005, Jeff Euston, Tierney's great-great-nephew, created a website tracking all salaries of MLB players, naming it "Cot's Baseball Contracts", after his baseball ancestor. Considered "the unofficial clearinghouse for MLB contracts", the website had 4 million page views by the end of 2008. In 2010, Baseball Prospectus purchased Cot's Contracts, and began hosting the site.
