On May 25, 1913, after giving the starting shortstop position to Ray Chapman, the Naps traded Peckinpaugh to the New York Yankees for Jack Lelivelt and Bill Stumpf.

[7] After considering the offer from Chicago,[8] he chose to stay with the Yankees, and received a three-year contract worth $6,000 ($180,711 in current dollar terms) per season from 1915 through 1917.

[10] By the 1921 season, Peckinpaugh was one of three players, along with Wally Pipp and Bob Shawkey, remaining with the Yankees from the time Jacob Ruppert and Tillinghast L'Hommedieu Huston purchased the team in 1915.

On December 20, 1921, the Yankees traded Peckinpaugh with Rip Collins, Bill Piercy, Jack Quinn and $100,000 ($1,708,209 in current dollar terms) to the Boston Red Sox for Bullet Joe Bush, Sad Sam Jones and Everett Scott.

[1] When Bill Veeck bought the Indians in July 1946, he brought Harry Grabiner and Joseph C. Hostetler with him to serve in the front office.

[37] After the end of his baseball career, Peckinpaugh worked as a manufacturer's representative for the Cleveland Oak Belting Company.

Suffering from cancer and heart disease, he was brought to a hospital for a respiratory condition, and died on November 17, 1977, in Cleveland.
