A guide to sabermetrics, the empirical analysis of baseball statistics

A guide to the best baseball books

If you're really all-in on the game, then you might want to dig into one of these classics, like Michael Lewis' "Moneyball," about the analytics that changed the sport, or Bob Uecker's autobiography, "Catcher in the Wry."

Visualizing how changes to lineups would impact historical baseball games

This visual essay maps how data-informed lineup construction has revolutionized baseball. Amid the embrace of analytics, the game's best overall hitters were moved from the third spot to second, power bats were shifted out of the "cleanup" role, and speedsters—typically the leadoff batters—were pushed to the bottom half of the nine-player lineup. Joe Carter, the hero of the '93 World Series, likely never hits his iconic walk-off from the cleanup spot in a modern lineup.

The 2011 film 'Moneyball' shifted ideas about sports and statistics

Based on the Michael Lewis book of the same name, the film starring Brad Pitt depicts the attempts of the 2002 Oakland A's to leverage data analysis to overcome their low-budget woes ($41M) and compete with big-budget teams like the New York Yankees ($125M). Other sports and leagues, including the NBA and NFL, would adopt a similar logic: find what the market undervalues and exploit it.

Inside MLB's robo-umping experiment

Human umpires call roughly 94% of pitches right overall, but performance reduces on borderline pitches in high-leverage moments, the calls that shape game outcomes most. A professor and historian analyze early experiments with the full "robot ump" system that helped shape MLB's decision to implement a compromise "challenge" system.

How Shohei Ohtani made baseball fun again

To rise to the level of Major League Baseball in recent decades, a player needs to become a specialist in at least one of the sport's many skills: hitting, pitching, throwing, running, fielding. For decades, this specialization has made a so-called...

A 1930s card game birthed modern fantasy sports

Henry Chadwick invented the box score in 1859—and wrote off walks as a pitcher's failure

The English migrant adapted cricket statistics for baseball, publishing the first box score in the game's early days. Baked into that was a dismissal of the walk as reflecting a batter's skill, instead implying it was a pitcher's mistake. That assumption kept walks out of the box score for more than a century, concealing the skill involved in drawing walks.

Statcast runs machine learning models in the 23-second gap between every pitch

The same Hawk-Eye cameras that track spin rate, exit velocity, and sprint speed also feed proprietary team models that update in near-real time. Some organizations have built streaming pipelines to surface insights mid-at-bat before the next pitch arrives.

Ranking every baseball stadium outfield by how hard it is to play

Park factors have long adjusted for how a ballpark helps or hurts hitters and pitchers, but rarely fielders. MLB's Statcast looked at five years of Outs Above Average data to shed light on the gap. It found that stadiums with roofs or in cities that regularly have sunny skies dominate the easy end, while those battered by wind or rain, like San Francisco's, are the hardest to play.

The physics of baseball pitches

To a nonfan, pitching a baseball may seem straightforward. Dive into the ridiculous physics of throwing a baseball at high speeds, from curveballs to sliders and more, and learn just how crucial those classic red seams of the baseball are in determining what the ball does in the air.

Major League Baseball, explained

Major League Baseball is America’s oldest professional sports league. Alongside triumphs, the league has faced scandals, including drug abuse and steroid use, shaping its path over the decades. Today, MLB embraces new rules, international talent, and a growing connection to legalized sports betting.

"Guessing what the pitcher is going to throw is 80 percent of being a successful hitter. The other 20 percent is just execution."

- Baseball star Hank Aaron (1934-2021)

How math whizzes exploit sportsbooks

Chris Dirkus is a professional sports bettor who approaches the hobby as a math problem, not from a fan's perspective. He focuses on mispriced odds in popular games where many fans are betting for high liquidity. He's one of a rare segment of sports bettors exploiting slow models and human mistakes.

'Scorigami' attempts to chart every NFL game score

The rules of the sport set bounds on possible final outcomes, so this adept statistician mined some fascinating takeaways. Some scores are impossible (like 5 to 1) and some are more common (like 20-17, occurring over 300 times since 1944). Watch for a deluge of numbers.

The evolution of the baseball bat

Torpedo bats may be the latest, most powerful kind of baseball bat, but the instrument's history is long. This Smithsonian resource traces the bat's evolution from handmade objects forged by the players to mass-produced marvels of physics designed by companies like Louisville Slugger. Along the way, you'll see some interesting takes on the form, including bats referred to as "mushrooms" and "bananas."

Long before Major League Baseball began allowing instant replay for balls and strikes, an umpire reluctantly used the technology to determine whether a hit was a home run, a move that inadvertently ushered in a new era for the sport.

Early MBA curricula were influenced by a movement in ‘scientific management’

The Scientific Management movement was pioneered by Frederick Winslow Taylor in the early 1900s and posited managers should take a scientific approach to work, studying each task and system in the workplace from an objective lens. It’s still considered the backbone of modern management practices.

How Seabiscuit's DNA made him a winner

Seabiscuit's sudden success in the sport has been framed as a classic against-the-odds sports story. One Binghamton University molecular physiologist wanted to go a bit deeper, though, to see how much genetics played a role in the horse's legendary career. Using the horse's silvered hooves, his research team discovered that Seabiscuit's genotype was typically associated with late bloomers, a finding confirmed by the horse's track record.

A 15-year bibliographic analysis identified systematic gender bias across Wikipedia

A 2024 study by the University of Barcelona found that 71.4% of all English biographies that appear on the front page are about men, and approximately one in five editors are women. Researchers suggest systemic imbalances in society further diminish women's contributions to the site by leaving them with less time to defend edits during editorial disputes.

Astronomers use a set of scaffolding methods to measure distances across the universe

Different methods are used depending on how far away an object is—from radar for nearby planets, to parallax for stars, to redshift and supernovae for distant galaxies.

Each scientific study adds incremental knowledge to existing understanding

On its own, no study serves as a source of truth or solves an existing problem indefinitely, though many can be analyzed collectively in a systematic review to build more confidence—the result of more data—in a conclusion. Studies can explore knowledge gaps or test an existing theory, which is always subject to refinement and improvement.

For more than three decades, US News & World Report has released an annual ranking of the country's best colleges. An extremely influential list that can determine application volume, funding decisions, and more, the rankings have been compiled by a secret algorithm indecipherable to many on the opposite side of the table. Author Malcolm Gladwell attempts to unpack the calculation, ultimately raising the question: How relevant is the list?
