walk-off

That drives in a run that ends a game.

Scott Podsednik hit the twelfth walk-off home run in World Series history on October 23rd, 2005.

By extension, any scoring event in sports that ends the game.

A prisoner who escapes custody without violence by taking advantage of the opportunity provided by negligent or distracted guards.

A walkout.

Any event or action in the bottom of the last inning of a game that scores a run and thereby ends the game with a victory to the team at bat.

It was the Brewers' first walk-off walk since May 4, 2005, when Damien Miller drew a walk to win the game, 4-3, at home over the Cubs.
