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. 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 (who must "walk off" the field with his head hung in shame), 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.
Jim Thome holds the MLB record for most career walk-off home runs with 13, the first being hit on June 15, 1994, and the last (which broke the previous record of 12) on June 23, 2012. Most notably, he hit his
500th career home run for a walk-off home run.
Freddie Freeman is both the only player to hit multiple walk off home runs in the World Series and the only player with a World Series walk-off grand slam.
Other types of "walk-off" wins Sportscasters have applied the term "walk-off hit" to any kind of hit that drives in the winning run to end the game. It is an expansion 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 terms "walk-off
hit by pitch", "walk-off walk" (a
base on balls with the bases loaded), "walk-off
wild pitch", "walk-off reach-on-
error", "walk-off
steal of home", "walk-off
passed ball", "walk-off
balk" (the latter being dubbed a "balk-off"), and even "walk-off
catcher's interference" have also been applied. The day after
Eric Bruntlett executed a game-ending
unassisted triple play for the
Philadelphia Phillies against the
New York Mets on August 23, 2009, the
Philadelphia Daily News used the term "walk-off triple play" in a subheadline describing the moment, although it was not a true walk-off.
Walk-off grand slam celebrate a walk-off grand slam hit by
Justin Maxwell in
2009. A
grand slam is a home run hit with all three bases occupied by baserunners ("bases loaded"), 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. Since 1916 there have been more than 250 walk-off grand slams hit during Major League Baseball's regular season. Since its institution in 1903, only two walk-off grand slams have been recorded in the postseason. The first was in Game 2 of the
2011 ALCS, by
Nelson Cruz of the
Texas Rangers. The second playoff grand slam was hit by
Freddie Freeman of the
Los Angeles Dodgers in Game 1 of the
2024 World Series. In Game 5 of the
1999 NLCS,
Robin Ventura of the
New York Mets hit
a game-winning home run with the bases loaded against the
Atlanta Braves, but as only the Mets player on third base –
Roger Cedeño – reached home before the Mets started their on-field celebration, the play was officially recorded as a
single. 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 (an 8–4 victory over the
Oakland Athletics) followed by his second on July 30 (an ultimate grand slam, for an 11–10 win over the
Los Angeles Angels), becoming the first player in MLB history to hit multiple walk-off grand slams within the span of a single week.
Ultimate grand slam A walk-off grand slam that erases a three-run deficit is also called an ultimate grand slam. There have been 32 such instances documented in major league history – all taking place during the regular season, 16 of those coming with two outs. Of the 32 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.
Del Crandall's September 11, 1955,
Alan Trammell's June 21, 1988, and
Chris Hoiles' May 17, 1996 grand slams occurred under the most dire situation possible: bases loaded, two outs, full count, bottom of the ninth inning, and down by three runs. The most recent ultimate grand slam was hit by
Giancarlo Stanton on September 20, 2022, in the
New York Yankees' 9–8 victory over the
Pittsburgh Pirates.
Walk-off celebrations 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. A walk-off celebration may involve hitters jumping on home plate before being encircled and caught by their teammates. 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 from jumping on home plate while celebrating a walk-off grand slam off of the
Seattle Mariners. 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==
