This book was a disappointment from page 1. The title of the book is suggests that this book would be based on an in-depth discussion of science and or math. It is not. It should be titled "Hey, Did you know that Baseball uses Science and Technology?", because there is very little explanation in this book, (but how many times can you tell me baseball uses computers to improve performance???). In the introduction...the author mentions "The Science of Baseball" and the "Physics of Baseball"...tempting the reader to think this is a modern book at those levels. It is not. If the self-inflicted expectations were not so high, maybe I would give it one more star.
After the first chapter, you know its going to be a let down. Dr. Wills is a topic in the chapter, she collected and dissected balls from many years...but there is no actual data provided. She mentions that there was one instance where there was an intentional change to the ball, but it performed opposite of what was expected. Great...please be specific...tell me what the change was...how they wanted it to perform...and why did it not meet expectations. But no...none of that.
We got close to science and data in chapter 4. We learn of an analytic called "Acute to Chronic Ratio". Awesome...something new. But the author doesn't even explain what it is. Then he points to a chart...again, how can I evaluate data and charts without knowing what the input variables are? At least tell me what an average ACR is and what might be considered extreme.
One final critique that I will mention...and it is really just bad luck for the author. This book came out in 2022. I started reading it while at spring training in 2023. The author mentions some things that might happen in MLB...but who knew the massive rule changes between 2022 and 2023. Pitching clock, limited pick-off attempts, and bigger bases...these will all have an impact on how the game is played, not just in length of games. They make his section on base stealing almost obsolete.
The author did open my eyes to the effect that robo-umps will have on the very important catcher skill of framing, so I learned something. But not worth 188 pages for that.
