Walk-off home run


In baseball, a walk-off home run is a home run that ends the game. It must be a home run that gives the home team the lead and the win in the bottom of the final inning of the game. Thus the losing team must then "walk off" the field immediately afterward, not finishing the inning, and the winning team can "walk off" the field with the win. The winning runs must still be counted at home plate.

History and usage of the term

Although the concept of a game-ending home run is as old as baseball, the adjective "walk-off" attained widespread use only in the late 1990s and early 2000s.
The first known usage of the word in print appeared in the San Francisco Chronicle on April 21, 1988, Section D, Page 1. Chronicle writer Lowell Cohn wrote an article headlined "What the Eck?" about Oakland reliever Dennis Eckersley's unusual way of speaking: "For a translation, I go in search of Eckersley. I also want to know why he calls short home runs 'street pieces,' and home runs that come in the last at-bat of a game 'walkoff pieces'..." Although the term originally was coined with a negative connotation, in reference to the pitcher, it has come to acquire a more celebratory connotation, for the batter who circles the bases with pride and with the adulation of the home crowd.

Other types of "walk-off" wins

Sportscasters also use the term "walk-off hit" as any kind of hit which drives in the winning run to end the game. The terms "walk-off hit by pitch", "walk-off walk", "walk-off wild pitch", "walk-off reach-on-error", "walk-off steal of home", "walk-off passed ball", and "walk-off balk" have been also applied, and the latter has been dubbed a "balk-off". It is a separate stretch of the term to call a hit a walk-off when what ends the game is not the hit but the defense's failure to make a play. The day after Eric Bruntlett pulled off a game-ending unassisted triple play for the Philadelphia Phillies against the New York Mets on August 23,, the Philadelphia Daily News used the term "walk-off triple play" in a subheadline describing the moment.

Walk-off grand slam

A grand slam is a home run hit with all three bases occupied by baserunners, thereby scoring four runs—the most possible in one play. A walk-off home run with the bases loaded is therefore known as a walk-off grand slam.
Starting in the 1990s, a walk-off grand slam that erases a three-run deficit has come to be known as an ultimate grand slam. There have been 29 such instances documented in major league history – all taking place during the regular season, 15 of those coming with two outs. Of the 29 home runs, only Roberto Clemente's was hit inside the park, at spacious Forbes Field on July 25, 1956. Pirates manager/third base coach Bobby Bragan instructed him to stop at third, but Clemente ran through the stop sign to score the winning run. Alan Trammell's June 21, 1988 and Chris Hoiles' May 17, 1996 grand slams occurred under the most dire situation: bases loaded, two outs, full count, bottom of the ninth inning, and down by three runs.
The most recent walk-off grand slam was hit by Matt Olson of the Oakland Athletics on July 24, 2020, against the Los Angeles Angels. Three players have hit two walk-off grand slams in a season, Cy Williams in 1926, Jim Presley in 1986, and Steve Pearce in 2017. Pearce's first was on July 27 followed by his second on July 30, becoming the first player in MLB history to hit multiple walk-off grand slams within the span of a single week.
Only five pitchers in major league history have surrendered two game-ending grand slam home runs in one season, according to the Elias Sports Bureau:
Walk-off celebrations typically consist of an entire baseball team leaving the dugout to meet a player at home plate after the batter hits a walk-off home run, or at whichever base the hitter happens to reach if a traditional base hit results in a walk-off victory. Players often encircle teammates who hit a walk-off before dancing and roughhousing to celebrate their victory. During a walk-off celebration on May 29, 2010, Kendrys Morales, then a member of the Los Angeles Angels of Anaheim, broke his left leg while celebrating a walk-off grand slam. As a result of this injury, team manager Mike Scioscia instituted new guidelines for his team that ensured a much tamer response to all subsequent walk-off victories.

Relevant rules

The rules of baseball provide that:
The first point above was problematic in the 1976 American League Championship Series between the New York Yankees and the Kansas City Royals. The Yankees and Royals entered the bottom of the ninth inning of the decisive fifth game with the score tied, 6–6; Mark Littell was the pitcher for Kansas City, and Chris Chambliss was the first batter for New York. Chambliss hit Littell's first pitch into the right field bleachers to win the game and the American League pennant for the Yankees. However, Yankees fans ran onto the field at Yankee Stadium to celebrate the victory, and prevented Chambliss from rounding the bases and touching home plate. Recognizing the impossibility of Chambliss successfully negotiating the sea of people who had been on the field, umpires later escorted Chambliss back out to home plate and watched as he touched it with his foot, thereby making the Yankees victory "official".
The third point above led to Robin Ventura's "Grand Slam Single" in the 1999 NLCS. In the bottom of the 15th inning, the New York Mets tied the score against the Atlanta Braves at 3–3. Ventura came to bat with the bases loaded, and hit a game-winning grand slam to deep right. Roger Cedeño scored from third and John Olerud appeared to score from second, but Todd Pratt, on first base when Ventura hit the home run, went to second, then turned around and hugged Ventura as the rest of the team rushed onto the field. The official ruling was that because Ventura never advanced past first base, it was not a home run but a single, and thus only Cedeño's run counted, making the official final score 4–3.
The fourth point above was not a rule prior to 1920; instead, the game ended at the moment the winning run scored. This rule affected the scoring of 40 hits, from 1884 to 1918, that would now be scored as game-winning home runs. Babe Ruth would have been credited with 715 career home runs had the modern rule been in effect in 1918; in a 10-inning game Ruth's fence-clearing, walk-off RBI hit was scored a triple because the game was deemed over when the lead baserunner reached home.

After Forbes Field was demolished, the section of the left-field wall where the home run left the park was moved to the Pirates' new home of Three Rivers Stadium, and still later was moved to their current home, PNC Park. A line of bricks marks that section of the wall, next to a preserved wall section, and a plaque indicating the spot where Mazeroski's homer left the park is embedded in the current sidewalk.

7–63–3Fisk's home run to lead off the 12th inning, high off the left-field foul pole above the Green Monster, ties the Series in one of the best remembered moments in the sport's history. The homer arguably changed the way televised sports are covered; because camera operators missed a cue from the producer, the camera lingered on Fisk trying to "wave his home run fair." This image of Fisk proved so dramatic that "reaction shots" became standard fare in sports broadcasting.

Oakland's José Canseco had provided all his team's scoring with a second-inning grand slam. Jack Buck, who called the game for CBS Radio, exclaimed "I don't believe what I just saw!" as Gibson circled the bases.
