The term walk off has run its course.... they hype it up yet are actually using it wrong. It was not meant to be a celebratory term, it was quite the opposite..... The term walk-off originated as "walk-off piece," and was coined by Hall of Famer Dennis Eckersley. ''It was always walk-off piece," Eckersley told the Boston Globe. "Like something you would hang in an art gallery. The walk-off piece is a horrible piece of art."
The first reference to walk-off came in a July 30, 1988, story in the Gannett News Service: "In Dennis Eckersley's colorful vocabulary, a walk-off piece is a home run that wins the game and the pitcher walks off the mound."
Walk-off piece was only intended to describe a pitcher's dejected walk off the field after giving up a game-losing home run
