What is the strike zone in Baseball ? It’s Time To Blow Up Strike Zone Definition

What is the strike zone in baseball ? Balls and strikes form the fundamental building blocks of the great American pastime. Without them, there would be no competitive baseball. Pitchers would never throw a ball near enough to a batter to hit. Batters would never swing until the perfect pitch arrived chest-high right down the middle of the plate.

Agreeing upon the place where a pitch is considered a strike or a ball solves that problem. Pitchers will walk batters if they don’t throw strikes. Batters will strike out if they don’t swing at good pitches. The area that determines whether a pitch is a ball or a strike is called the strike zone.

How Big Is the Strike Zone in Baseball?

It’s a common question in baseball. Where is the strike zone in baseball and how big is it? To explain, we will use the rules of Major League Baseball, which are followed by most serious baseball players.

What Are the Dimensions of a Baseball Strike Zone?

Unlike the dimensions of an object, the baseball strike zone has no fixed numerical dimensions. Rather, the strike zone is determined by reference points on the human body.

This is because players come in all shapes and sizes. The strike zone increases or decreases according to the size of the player. This gives all players an equal chance, no matter how big or small they are.

The most striking example of the adaptability of the rules came in 1951, when the St. Louis Browns sent pinch hitter Edward Carl Gaedel to the plate. The smallest player ever to appear in Major League Baseball, Gaedel was a person with dwarfism who stood 3 feet 7 inches tall and weighed about 65 pounds. In his one MLB appearance, he walked on four consecutive pitches – as a controversial publicity act planned by Bill Veeck, owner of the Browns and son of the Cubs president.

What Determines a Baseball Player’s Strike Zone?

In addition to size, the stance of a player determines the strike zone. The more a player crouches, for instance, the smaller the strike zone.

The MLB rules for the strike zone are simple. At least a portion of the ball must pass over home plate. To count as a strike vertically, the pitch must pass at the top between the midpoint of the player’s shoulders and the top of the pants. This is sometimes defined as the letters on the front of the player’s jersey. The lower part of the strike zone is defined as just below the kneecaps.

What Year Was the Smaller Strike Zone Initiated in Pro Baseball?

Besides causing hot controversies on the field and in the stands, the strike zone has been subject to longer-term debate in MLB executive suites. As such, its definition has been changed from time to time.

The first official strike zone was implemented in the late 1800s and has gone through a series of changes.

The first time the definition of the strike zone changed took place in 1950, when the zone was downsized from the area between the top of the batter’s shoulders and the knees to the zone between the batter’s armpits and the top of the knees. This rule lasted until 1962, when the zone was expanded. From 1963 to 1968, the strike zone went from the top of the batter’s shoulders to the knees.

Then from 1969 to 1987, the strike zone went from the batter’s armpits to the top of the knees. At the same time, the pitcher’s mound was lowered from 15 inches to 10 inches, in response to the 1968 season – known as the “Year of the Pitcher” – because of the ability of pitchers to continuously throw strikes.

From 1988 to 1995, the rule changed again and the strike zone went from the midpoint between the shoulders and the top of the uniform pants to the top of the knees.

The most interesting thing about the strike zone is that while there is a rulebook definition of it, the interpretation of the zone is an ever-changing thing.

Simply put, the strike zone is an area over home plate and towards the middle of the hitter’s body that a pitcher must hit consistently to have any chance of success. From a batter’s point of view, the strike zone is the area where hitters see the most hittable pitches.

Because both the batter and the pitcher need pitches in the strike zone to be successful, this is where the cat-and-mouse game between pitcher and batter is evident.

A pitcher wants to hit the strike zone, but only around the edges where it’s harder for a hitter to make solid contact. Likewise, a hitter wants the pitcher to get too much of the strike zone and take advantage of a pitch in the middle of the plate.

Because the strike zone is technically invisible and will have a different shape depending on the batter at the plate, it is unique in that the zone is never uniform, even at the highest levels.

Additionally, different governing organizations have different rules on the strike zone, meaning that different levels have different zones.

How Is the Strike Zone Determined?

Because strike zones are ultimately up to the umpire’s discretion, they will vary, but as stated, there are definitions at every level as to how they should be called.

At the major league level, the strike zone is defined as the midpoint between the batter’s shoulders and beltline and the bottom of the hitter’s knees, as well as the area directly above home plate.

Of course, there is plenty of interpretation to be had with a definition like that. The midpoint can be interpreted differently by different umpires.

That point usually ends up around the bottom of a part of the jersey commonly referred to as the “letters,” which is named because many teams have their team or city name (or a logo) spelled across the chest, hence why it is called the letters.

Scientifically speaking, according to Sports Information Solutions, for the average MLB hitter the strike zone spans from 1.5 feet off the ground to 3.6 feet off the ground.

With home plate being 17 inches wide, the zone is a minimum of 17 inches wide as well, though it’s usually a few inches wider.

Generally, in American baseball, relative to the size of the player, strike zones tend to start off larger as players begin playing, then shrink as they get older.

We consulted a veteran youth baseball umpire to offer his insight at how strike zones evolve at different age levels.

He said that at the earliest ages of kid pitch (8-10 years old), strike zones may range from as high as the shoulders to the mid-shins, with perhaps 4-6 inches on each side of the plate given.

This tends to shrink gradually until high school when the strike zone begins to resemble the same boundaries as the college and professional strike zones.

Even when the strike zone is more or less set, there are factors in play that determine how big or small it is. One factor is that the definition of a strike zone does not define whether all of the baseball or just part of it must cross a certain area to be considered a strike.

As a result, a strike zone that is defined as being directly over home plate (which is 17 inches wide) could vary wildly in width.

According to the rules of baseball, a strike is when any part of a pitch passes over the plate and within the strike zone.

Only part of the ball must be over the 17-inch plate to be a strike, in essence making their strike zone roughly 23 inches wide, though some umpires may want more of the ball to catch the plate to consider it a strike.

This same line of thinking can be applied at the top or bottom of the strike zone as well, which suddenly means that two otherwise-identical strike zones may all of a sudden vary by a few inches both up-and-down and side-to-side because different umpires choose to apply the wording differently.

Another key factor in the size of the zone is a player’s size. Because Jose Altuve stands just 5’6” tall, his strike zone will be several inches shorter than that of Aaron Judge, who is 6’7”.

How Does the Strike Zone Affect the Game?

The exact impact that a big or small strike zone can have on a game isn’t exactly nailed down, but in general, it’s agreed that the size of the strike zone can have a direct impact on the balance between hitting and pitching.

A large strike zone generally favors pitchers, while a smaller strike zone generally favors hitters. There are usually some traits you can pick up that will highlight this tendency.

These factors could be mitigated by having a certain type of pitcher on the mound or an offense geared around certain traits, but generally, a large zone will allow pitchers to work farther away from the middle of the plate without the risk of walking an exorbitant amount of batters.

At the same time, once hitters pick up on a strike zone being large, they may be more inclined to swing at borderline pitches that they may have otherwise taken.

Because hitters may feel forced to swing with a larger strike zone, some people believe it speeds up the pace of play, though it’s hard to specifically prove. Our youth baseball umpire said that advice from his early supervisors suggests this is the case.
