===Walk-off home run===
{{Main|Walk-off home run}}
A walk-off home run is a home run hit by the [[home team]] in the bottom of the ninth inning, any [[extra inning]], or other scheduled final inning, which gives the home team the lead and thereby ends the game. The term is attributed to [[National Baseball Hall of Fame and Museum|Hall of Fame]] [[relief pitcher]] [[Dennis Eckersley]],<ref name="eck_walk_off">{{cite news|first=Lowell|last=Cohn|title=What the Eck?|work=San Francisco Chronicle|date=April 21, 1988|page=D1}}</ref> so named because after the run is scored, the losing team has to "walk off" the field.

Two [[World Series]] have ended via the "walk-off" home run. The first was the [[1960 World Series]] when [[Bill Mazeroski]] of the [[Pittsburgh Pirates]] hit a ninth-inning solo home run in the seventh game of the series off [[New York Yankees]] pitcher [[Ralph Terry]] to give the Pirates the World Championship. The second time was the [[1993 World Series]] when [[Joe Carter]] of the [[Toronto Blue Jays]] hit a ninth-inning three-run home run off [[Philadelphia Phillies]] pitcher [[Mitch Williams (baseball)|Mitch Williams]] in Game 6 of the series, to help the Toronto Blue Jays capture their second World Series Championship in a row.

Such a home run can also be called a "[[Sudden death (sport)|sudden death]]" or "sudden victory" home run. That usage has lessened as "walk-off home run" has gained favor. Along with Mazeroski's 1960 shot, the most famous walk-off or sudden-death home run would most likely be the "[[Shot Heard 'Round the World (baseball)|Shot Heard 'Round the World]]" hit by [[Bobby Thomson]] to win the 1951 National League pennant for the [[New York Giants (NL)|New York Giants]], along with many other game-ending home runs that famously ended some of the most important and suspenseful baseball games.

A walk-off home run over the fence is an exception to baseball's one-run rule. Normally if the home team is tied or behind in the ninth or extra innings, the game ends as soon as the home team scores enough runs to achieve a lead. If the home team has two outs in the inning, and the game is tied, the game will officially end either the moment the batter successfully reaches first base or the moment the runner touches home plate—whichever happens last. However, this is superseded by the "ground rule", which provides automatic doubles (when a ball-in-play hits the ground first and then leaves the playing field) and home runs (when a ball-in-play leaves the playing field without ever touching the ground). In the latter case, all base runners including the batter are allowed to cross the plate.
