Economics applied to baseball—that was my thinking in choosing to add this to my economics reading list. It wasn't that heavily into the theory, though, as in the the stories surrounding those who applied new ideas about statistics to sports, and specifically baseball and the early 2000s Oakland A's. In a way, the book adhered much more closely to the movie based on it than I would have imagined. That is, it was much more centered on Billy Beane's life and how his experiences shaped his work as general manager of the team. For a baseball fan, especially for one who grew up in the 1980s, with Bill James's abstracts and Status Pro Baseball, this book is a really fun read; given its heavily narrative nature, I'm not sure how much one gets from it from an economic theory perspective.
For me, much of the book was about how little I know about baseball of the era that Lewis writes about. I followed baseball deeply as a preteen and early teen, from about age twelve to sixteen, and continued to know it fairly well through the miraculous 1988 Dodgers season, when I turned eighteen. But once I started work and especially after I graduated from high school, I found myself with much less time to devote to the sport. Sure, I might check in on how a team is doing from time to time and who are the stat leaders, but I don't listen to virtually every game of my team, scour stats on summer days, or spend those days playing simulation games. As such, players come and go and I know nothing of them. This means, that outside of Jason Giambi, Tim Hudson, Barry Zito, and Nick Swisher, I knew virtually none of the players discussed in this book. And even of the four mentioned, I knew almost nothing of them, other than that they were for a while very good players. I found myself, as such, looking up some of the other players Lewis writes about.
The essence of the book is an attempt to answer how it is that the A's of the early 2000s, one of the cheapest teams in the sport, managed to put up teams that were constant winners. The answer is, of course, to any familiar with what has become standard now in the stport, by paying attention to statistics that others aren't. Things like batting average, for example, really aren't as important as on base percentage. ERA isn't as important as walk-to-strike ratio or homers pet batters. It's these sort of stats that the A's started recruiting with and building a team around. Such was essential, because a poor team like the A's can't afford to keep players like Jason Giambi, who can hit for power and average, so instead one gathers nonnames who actually do significant things.
Beane was apparently an incredible athlete and a potentially great player, but his major league career never panned out. The issue for him was psychological. He couldn't deal with getting out. The game is as much mental as physical. As a result, he floundered, until one day he quit—or sort of did. He walked from the clubhouse into the back office and asked instead to work there, which is odd coming from a relatively young player.
Thereafter, we learn about Bill James and his baseball writing. We learn about why the A's don't run. We learn about various players the A's recruited, such as the catcher Jeremy Brown (an on-base machine who is otherwise not that impressive and thus of no interest to other teams) or the pitcher Chad Bradford (whose low velocity and weird delivery disinterested other teams, despite statistical major- and mostly minor-league success, but whose extremely high groundball rate was of particular interest to the A's). We see how Beane goes about trading with other teams and drafting players, and how his success has meant that he's had to find ways to do so deviously such that teams don't realize who he's really after and thus raise the price.
Lewis's book is a throwback in a way, to a time when the sport was first discovering the more efficient way of operating. Teams like the A's and Rays could still take advantage. I'm not sure that's as much the case anymore, as teams like the Dodgers have both the money and the brains now, and it's sad really. In addition, the focus on stats has taken away for many teams things like the steal and encouraged things like the shift, making for more predictable play. Pro baseball has attempted to adjust the rules, making larger bases, taking away the shift as a legal move, as to bring some things back, but at the same time, it's also encouraged more homers and jettisoned pitchers batting such that to one who enjoys the strategy element of the sport, it seems less interesting than it once did.
