Harold John Deviney (April 11, 1893 – January 4, 1933) was a relief pitcher in Major League Baseball who played in one game for the Boston Red Sox during the 1920 season.
He batted and threw right-handed.
A native of Newton, Massachusetts, Deviney was a major league player whose career, statistically speaking, was only slightly different from that of Eddie Gaedel or Moonlight Graham.
On July 30, 1920 Deviney posted a 15.00 earned run average with three walks in 3.0 innings of work.
He did not have a decision.
But Deviney had more luck at the plate, going 2-for-2 with one run and a triple for a perfect 1.000 batting average.
He never appeared in a major league game again.
Deviney died in Westwood, Massachusetts, at age 39.
