Why Baseball Is Designed the Way It Is : Subscriber Episode

A Curious by Design Subscriber Special

The crack of the bat.

The pause before a pitch.

The slow rhythm of a game that seems to move at its own pace.

Baseball feels timeless—but every part of it was designed.

In this subscriber special of Curious by Design, we explore how baseball became one of the most carefully structured games ever created. From the perfect geometry of the diamond to the precise distance of ninety feet between bases, the sport evolved through decades of experimentation until its rules produced the balance fans recognize today.

The episode traces how early figures like Alexander Cartwright helped formalize the game’s structure, why the pitcher stands exactly sixty feet and six inches from home plate, and how the design of the baseball itself—its cork core and 108 red stitches—affects how pitches move through the air.

We also look at what makes baseball unique among sports: a game without a clock, built around outs rather than time. That structure creates something rare in sports design—endless possibility. No matter the score, every team always gets its final chance.

From the unpredictable geometry of ballparks to the rhythm of anticipation between pitches, baseball blends mathematics, physics, and psychology into a system built to produce unforgettable moments.

Because baseball isn’t just a sport played on grass.

It’s a design refined over more than a century—

one built to create moments that last a lifetime.

That’s Curious by Design.

Welcome to Curious by Design. I'm your host, Jason Hardwick. This is the show about how things get built and why they end up the way they do. We tend to think design is about logos, architecture, or how something looks. But in reality, design is about choices. It's about trade-offs. It's about the invisible decisions that shape businesses, cities, systems, and even our everyday lives. On this podcast, we explore the thinking behind the work, how we got here, what worked, what didn't. All starting from the same place. Curiosity. A way to understand what's working, what's broken, and how we might design things better. If you've ever found yourself asking, why did they do that? You're in the right place. This is Curious by Design. Think about a baseball game, the crack of a bat, the sound of a ball hitting leather, the slow rhythm of a pitcher stepping onto the mound, a stadium stretching out under the sun, nine players in the field, a diamond carved into green grass, and a crowd that rises to its feet when a ball climbs into the sky. Baseball moves differently than most sports. It's slower, more deliberate. Moments stretch longer. A pitcher pauses, the batter adjusts his stance, the crowd waits. Then suddenly, everything happens at once. The pitch, the swing, the ball flying into the outfield. For a few seconds, the entire stadium holds its breath. Baseball has a rhythm that feels almost timeless, but that rhythm didn't appear by accident. Every part of baseball, the field, the rules, the statistics, even the length of the game, is the result of design. Design shaped by history, mathematics, human perception, and more than a century of evolution. Because baseball isn't just a sport, it's a system. One of the most carefully structured games ever created. The modern version of baseball traces its roots back to the 1800s. Games involving bats and balls existed long before that. But the version that resembles today's game began to take shape in the mid-19th century. One of the key figures in formalizing the early rules was Alexander Cartwright. The diamond-shaped field, three outs per inning, nine players per team, ninety feet between bases. Those numbers weren't random. They were chosen through experimentation. Early baseball games had different rules. Fields varied. Base distances changed. Teams tried different formats. Over time, certain arrangements simply worked better. Ninety feet between bases created the perfect balance. Far enough to make running difficult, but close enough to make close plays possible. That single measurement shapes almost every play in baseball. Ground balls, steals, double plays, bang bang plays at first base all depend on that precise distance. Change it by even a few feet, and the entire game would feel different. The field itself is also designed with remarkable geometry. The infield forms a perfect square, 90 feet on each side. Rotate that square 45 degrees, and you get the diamond shape we recognize. The pitcher stands 60 feet and 6 inches from home plate. That oddly specific number has a history. In the early days of baseball, the distance was shorter. Pitchers began dominating hitters. So the mound was gradually pushed back. In 1893, the modern pitching distance was adopted. That extra space gave hitters just enough time to react. Even today, a baseball thrown at 95 miles per hour reaches the plate in roughly four tenths of a second, less than half a second for the batter to decide whether to swing, which makes hitting a baseball one of the most difficult tasks in sports. But the physical design of baseball goes beyond measurements. The game itself is structured differently than almost every other major sport. Most sports are governed by time. Football, basketball, soccer all rely on a clock. When time expires, the game ends. Baseball doesn't work that way. There is no game clock. Instead, baseball is structured around outs. Each team must record 27 outs to finish a full game. That design changes everything, because no matter how far behind a team might be, they always get their final chance. Three outs in the ninth inning, a last opportunity to score. This structure creates one of the defining emotional features of baseball: hope. No matter the score, the game isn't truly over until the final out. Baseball also unfolds in a series of small moments. A pitch, a swing, a throw, a catch. Each play begins from stillness, then explodes into action. This stop and start rhythm is unusual in sports, but it creates something fascinating, anticipation. Fans have time to think between plays, to analyze strategy, to imagine what might happen next. This pacing makes baseball deeply connected to statistics. More than almost any other sport, fans track batting averages, earned run averages, on base percentages, slugging percentages. These numbers tell stories. Patterns emerge over time. A player who succeeds three out of ten times is considered excellent, which sounds strange at first, but that's the nature of baseball. Failure is built into the design. Even the best hitters in history fail most of the time. That balance between success and failure creates drama. Because every hit, every home run, every game winning moment is rare. And rarity makes moments feel meaningful. The baseball itself is also a carefully engineered object. A Major League Baseball weighs about five ounces. It's made from a cork center wrapped tightly with yarn, covered in white leather, and stitched together with exactly 108 red stitches. Those stitches aren't just decorative. They affect how the ball moves through the air. When a pitcher throws a curveball, the spin interacts with air resistance, creating something called the Magnus effect. That effect causes the ball to bend, to drop suddenly, or slide sideways. Pitchers manipulate spin to create different types of pitches fastballs, curveballs, sliders, change ups. Each pitch type relies on subtle variations in grip and release. Tiny adjustments in finger placement can dramatically change the ball's movement, which is why pitching is often described as an art. Baseball stadiums are also unique. Unlike basketball courts or football fields, no two baseball stadiums are exactly the same. Outfield walls vary in height. Distances to the fence vary dramatically. Some stadiums include deep center fields. Others have short porches near the foul poles. These differences create personality. A ball that would be a home run in one stadium might be a routine out in another. One of the most famous examples is Fenway Park. Fenway's left field wall, known as the Green Monster, is more than 30 feet tall. Hitters adjust their approach depending on the stadium they play in. Pitchers do the same. The environment becomes part of the strategy, part of the story of each game. Sound also plays a huge role in the experience of baseball. Unlike many sports, baseball has quiet moments, long pauses between pitches, which means the sounds of the game become part of the atmosphere. The snap of a fastball hitting the catcher's glove, the crack of a wooden bat, the roar of the crowd when a ball sails toward the outfield wall. These sounds create emotional cues. Fans recognize the sound of solid contact instantly, before they even see where the ball goes. It's one of the few sports where sound alone can signal success. Baseball also carries an unusual relationship with time. Games don't have fixed lengths. Some finish in under two hours. Others stretch beyond four. Extra innings can extend games indefinitely. Historically, this unpredictability became part of baseball's charm. A game could unfold slowly, like a story, with tension building gradually. In recent years, leagues have experimented with changes to speed up the game. One of the most notable changes is the pitch clock, implemented by Major League Baseball. The pitch clock limits how long pitchers can take between pitches, encouraging faster pace, shorter games. But even with these changes, baseball remains defined by its unique rhythm, a balance between patience and action. Baseball also plays a powerful cultural role. For generations, it has been called America's pastime. The sport grew alongside the expansion of the United States. Railroads carried teams between cities. Newspapers printed box scores daily. Fans followed players across entire careers. Baseball became woven into everyday life. Summer afternoons, radio broadcasts, family trips to the ballpark. The game became more than competition. It became tradition, a shared experience across generations. Few moments capture the emotional power of baseball better than a walk-off home run. Bottom of the ninth, two outs, game on the line. The pitcher throws, the batter swings, the ball rises high into the night sky. For a moment, everyone in the stadium watches. The crowd stands. The outfielder turns. The ball clears the wall, and the game ends instantly. No buzzer, no final whistle, just the sudden realization that everything has changed. Those moments are rare, but they're unforgettable. Because baseball is designed to allow them. The next time you watch a baseball game, take a moment to notice the design around you, the perfect geometry of the diamond, the ninety feet between bases, the pitcher standing sixty feet and six inches away, the rhythm of pitch after pitch. Every element exists for a reason. A system refined over more than a century, balancing skill, strategy, and chance. Because baseball isn't just a sport played on grass, it's a carefully constructed experience. One built to create moments that fans remember for a lifetime. And that's curious by design. Seriously, your support is what makes episodes like this possible. It gives me the time to dig a little deeper and to explore the strange, hidden design decisions that shape the world around us. The things most people walk past, but once you notice them, you can't unsee them. And if there's something you've always wondered about, some object, some system, some everyday thing that makes you stop and think, why is it like that? Send it my way. Because some of the best episodes start with a simple question. And remember, that's curious by design.
