n. 走离；离开；走下舞台

walk-off \walk"-off`\, a. (Baseball)
Game-ending and game-winning; such as to end the game
immediately, and allow the players to walk off the field; --
of hits, especially home runs, which occur in the last half
of the ninth or a later inning, which put the home team ahead
of the visiting team and thereby end the game immediatey.
This occurs in baseball because, when the last half of the
ninth inning arrives, if the home team (which bats last) is
already ahead in the score the last half of that inning is
not played, the winner of the game having already been
decided. Likewise, as soon as the home team gets ahead in the
score after the visiting team has batted in the ninth inning,
the game is ended. [Baseball jargon]

Curtis's homer over the left-center-field fence beat
the Braves and was the first walk-off homer by a Yankee
in the World Series since Mickey Mantle slugged one
against the St. Louis Cardinals in game 3 in 1964.

There are so many people in here who are happy for
Chad. We know what he's been through. Those hits could
make Chad Curtis's whole year. When you hit a walk-off
homer in the World Series, that's something he's going
to remember for a long time. --Paul O'Neill
