Baseball is a game of records with different terms. Knowing about different terms and stats is fun and enjoyable and also gives an idea about the players’ abilities. 

There are some events that happen rarely in a match such as a cycle, grand slam, etc. Fans of baseball have a greater than 8% chance throughout their lifetime of seeing a grand slam.

But what is a grand slam in baseball? Grand slam allows offensive teams to get home runs in a surprising way. 

By the way, I will explain everything about the grand slam in baseball. All manner with the grand slam, I will discuss several facts, including major league career grand slams, first career grand slam, single-season record, the first team record, all-time career leader, and so on.

So, sit tight, and let’s learn what it actually is and how it works.

What is Grand Slam in Baseball?

Grand Slam in Baseball

If you are very fortunate, you may have seen a hitter drive in four runs with a single hit.

Okay, if not, no worries. Actually, it is such a phenomenon that rarely happens.

Basically, a grand slam happens in baseball with bases loaded. That means, while a batter hits a ball, all three bases are occupied by three basemen. By this time, the batter hits the ball and completes a home run himself.

Therefore, hitting a grand slam is not something that often happens in baseball. You may rather argue that it is a very uncommon occurrence.

When a hitter hit a grand slam, it means he also gets 4 RBIs (Run Batted In) and a home run. Basically, in baseball, most grand slams occur while the at-bat balls go over the fence.

Former and late Seattle Mariners lead commentator Dave Neihaus called grand slam grand salami. Many players also used the “grand salami” term till early 1966.

See all grand slams in the 2021 MLB season.

Generally, a grand slam occurs with the ball getting out of the fence. But, sometimes inside-the-park grand slams also happen. Though the number of an inside-the-park grand slam is rarer than the regular slams.

Inside-the-park grand slam means when a batter hits the ball and gets a grand slam, but the ball stays inside the fence of the baseball field.

According to the data of Baseballcounter, there are 224 inside-the-park grand slams that happened in MLB.

To acquire an inside-the-park grand slam, you must be very fast as the ball stays inside the field. Also, it is sometimes a matter of luck that the balls get unusual bounces after landing on the ground.

The First Grand Slam in Baseball History

Roger Connor is the first ever grand slam holder in MLB history, 1881

The first major league grand slam took place almost 141 years ago. It’s always something matter of trill to talk about history.

By the way, here is a brief of the first grand slam in MLB history.

According to the Major league record, the first grand slam holder is Roger Connor.

First Grand Slam HolderRoger Connor
Year10th of September 1881.
GameTroy Trojans vs the Worcester Worcesters in National League (Present MLB)

It was a game between Troy Trojans and the Worcester Worcesters. The game was the first witness to the first grand slam. It was the ninth inning of the game (What timing!).

The bases were loaded, and Roger Connor of Troy Trojans was on the plate. Baseball history first ever witnessed a grand slam that truly amazed the visitors of that match.

The Albany Morning Express posted an article later on the 12th of September on the phenomenon. I am quoting the exact words they had written that day.

The few persons who crossed the river Saturday to the Troys and Worchester play saw an astonishing game of baseball. To the surprise of all, the Troys won the game by a long and lucky hit in the last inning.

By the way, the first grand slam was not considered an official record. But, it became official after the National League became Major League in 1903.

How Often Does a Grand Slam Happen in MLB Games?

The possibility of a grand slam in every 18 games, on average

The grand slam is such an uncertain phenomenon that it rarely happens.

By the way, to be honest, I have found a brief data of the grand slams in baseball of the 2018 season.

In the 2018 season, there were total home runs of 5585. Among them, there are 141 grand slams happened. So, if you see, the average of happening grand slams compare to home runs is 2.52%. However, it’s very rare.

By the way, what do you think about the scarcity of grand slams?

You can take into account two primary reasons for that.

  1. Bases loaded are not a frequent phenomenon. So, it’s not up to the batter that he just takes a homer as per his wish. Luck must favor here.
  2. Just bases loaded are not the only chance. The batter needs to hit the ball for enough distance, which is a tough task.

By the way, according to KeepThatShort, Major league baseball has been experiencing, on average, 135.6 grand slams from 1998 to 2008 per season.

The possibility of a grand slam in every 18 games, on average. 

ERA is one of the most important and crucial states for the pitchers. I believe “What Is ERA In Baseball? | A Wide Explanation” will amaze you with the great stat.

Difference Between Grand Slam and Home Run

If you have already understood the meaning of what is a grand slam in baseball, you might also understand the difference between a grand slam and a homer.

You may get a home run even if there is no baserunner(s) n the base. Or, there might be one or two baserunners. Also, you can get the highest 3 runs from a home run.

But in the grand slam, you will get 4 runs. Also, the bases must be loaded. 

What is Walk Off Grand Slam?

Before knowing what a walk-off grand slam is, it is important to know what is a walk-off homer.

By the way, a home run that finishes the game is referred to as a “walk-off home run.” As a general rule, a walk-off home run only counts if it is hit in the bottom of the ninth inning.

Also, the home run must exceed the run of the opponent team so that the game ends.

As a direct consequence of this, it is not necessary for the offensive team to play out the whole inning. Instead, they are free to leave the playing field immediately.

So, what is a walk-off grand slam, then?

Now the term might be easy to explain.

A walk-off home run will be considered a walk-off grand slam when it happens along the bases loaded. That means a grand happens with the rules of a walk-off homer. 

Along with the walk-off grand slam, knowing about walk-offs in baseball would be a great aspect of understand the relevant things. You may like to go through our post on What Is A Baseball Walk Off | Everything About Walk Off.

Walk-Off Grand Slam Records

From 1916 to today (August 2022), In the history of the major leagues of baseball, there have been approximately 260 walk-off grand slams. Aside from this, only one walk-off postseason grand slam has happened since 1903.

Nelson Cruz, the Texas Ranger’s hitter, had done this in the 2011 American League Championship Series.

By the way, the latest walk-off grand slam is done by New York Yankees’ Josh Donald in the current season of this year. He did this on the 17th of August, 2022.

Even Donald entered the “Ultimate grand slam” club with his latest walk-off grand slum (his 7th of career grand slams).

Notable Grand Slams by Players

Alex Rogriguez is the all-time grand slam leader in baseball with 25

As I mentioned before, Roger Connor is officially the first man declared to get the first ever grand slam in MLB history. On September 10, 1881, he did this for Troy Trojans.

The Troy Trojans fans in the Riverfront Park were crazy that day.

On the other hand, another grand slam occurred in 1871 in National Association. Charlie Gould for Boston Red Stocking hit the grand slam. But, as the National association is not recognized as an MLB league, it is not considered the first grand slam in MLB history.

Aside from this, Alex Rodriguez is the man who is the all-time leader of baseball grand slams. He won 25 career grand slams in his bag.

But, two names come up if you look at the man who holds the single-season record. Don Mattingly and Travis Hafner hold the single-season record. They got six grand slams each in 1987 and 2006, respectively.
