Moneyball: The Art of Winning an Unfair Game by Michael Lewis is about how the Oakland Athletics used Math and Statistics in the late 1990s and early 2000s to draft baseball players instead of the conventional wisdom of baseball scouts. Who knew you didn’t have to look like a baseball player with a tall, athletic body type to be an effective player?
Billy Beane used numbers to justify draft picks and trades and was able to win a lot of baseball games with the Athletics over teams with much bigger salaries. They never did win a world series during the years the book covers, though.
I liked it. Shows the value of stats.
