Cotton (Cot) Tierney was my grandfather's uncle. His full name was James Arther Tierney, and he was from Kansas City.
He reached the majors in late 1920 at age 26, after serving in WWI. He played in the majors until 1925. From 1926 to 1928, he played in the minors in Minneapolis, KC, Hollywood (Calif.) and Pueblo (Colo.).
He is one of the five players in major-league history to play in all three games of the only triple-header in major-league history, which was played Oct. 2, 1920 in Pittsburgh.
His .345 batting average ranked fifth in NL in 1922, the season Rogers Hornsby hit .401.
After retiring, Cot & Hall of Famer Zach Wheat, a former teammate, established Tierney-Wheat Recreation, a bowling alley, in Kansas City. He died in 1953, at age 59.
