Keith Law

Keith Law is an American baseball writer and analyst whose career has included scouting, statistical evaluation, and work in a major league front office. He began writing for Baseball Prospectus in 1997 and joined the Toronto Blue Jays in 2002. His responsibilities there included analysis, scouting, and contract work. He later wrote for ESPN before joining The Athletic in 2020.

Law’s books explain how baseball organizations assess information and make decisions. Smart Baseball examines the strengths and limitations of familiar performance statistics. The Inside Game turns to the ways people interpret evidence, including the biases that can lead experienced decision-makers toward poor conclusions. Both books use baseball examples to explain ideas that also apply to evaluating information outside sports.

Law studied sociology and economics at Harvard University and earned an MBA at Carnegie Mellon University. His professional background brings together two approaches often discussed separately in baseball: observing players through scouting and measuring performance through analysis. His books reflect that combination. They examine the information available to evaluators while also considering how people choose to use it.

The two titles address different stages of evaluation. A statistic can provide an incomplete description of performance even before anyone interprets it. A better measure can then be misused if the evaluator gives too much weight to a recent event or protects an existing belief. Law’s bibliography treats those as connected problems. Knowing the number and understanding the decision are related tasks, but they are not interchangeable.

The books are separate investigations with complementary questions. Their shared setting is baseball, but one emphasizes measurement and the other examines the reasoning that turns information into a choice.

Baseball Books

Smart Baseball: The Story Behind the Old Stats That Are Ruining the Game, the New Ones That Are Running It, and the Right Way to Think About Baseball: Law explains why traditional measures such as batting average, pitcher wins, and saves can give misleading impressions of baseball performance. He introduces alternative ways to evaluate players and describes the development of modern statistical analysis. The book places the numbers in practical context, showing how the choice of a measurement affects judgments about talent and value.

The Inside Game: Bad Calls, Strange Moves, and What Baseball Behavior Teaches Us About Ourselves: Using decisions from baseball history, Law examines how cognitive bias and flawed reasoning affect teams, executives, and other participants. He applies ideas from behavioral science to choices about players and strategy. The emphasis is on how conclusions are reached: what evidence receives attention, what assumptions remain unexamined, and why a reasonable-looking process can produce a poor decision.

Smart Baseball is primarily concerned with the tools used to describe the game. Its discussion gives readers a basis for questioning familiar labels and comparing what different statistics actually measure. The Inside Game moves the focus to judgment. It considers the people making choices and the habits of thought that influence them, even when more information is available.

Read together, the books trace a progression from collecting evidence to acting on it. They offer explanations rather than a team-by-team history, player memoir, or season diary. Law’s experience in baseball operations supplies relevant professional context, while the books’ subjects remain accessible questions: how to describe performance accurately and how to make decisions without allowing misleading signals to dominate the evidence.
