Just before the 2002 season opens  the Oakland Athletics must relinquish its three most
prominent (and expensive) players and is written off by just about everyone-but then comes
roaring back to challenge the American League record for consecutive wins. How did one of the
poorest teams in baseball win so many games?   In a quest to discover the answer  Michael Lewis
delivers not only "the single most influential baseball book ever" (Rob Neyer  Slate ) but also
what "may be the best book ever written on business" ( Weekly Standard ). Lewis first looks to
all the logical places-the front offices of major league teams  the coaches  the minds of
brilliant players-but discovers the real jackpot is a cache of numbers?numbers!?collected over
the years by a strange brotherhood of amateur baseball enthusiasts: software engineers 
statisticians  Wall Street analysts  lawyers  and physics professors.   What these numbers
prove is that the traditional yardsticks of success for players and teams are fatally flawed.
Even the box score misleads us by ignoring the crucial importance of the humble base-on-balls.
This information had been around for years  and nobody inside Major League Baseball paid it any
mind. And then came Billy Beane  general manager of the Oakland Athletics. He paid attention to
those numbers?with the second-lowest payroll in baseball at his disposal he had to?to conduct
an astonishing experiment in finding and fielding a team that nobody else wanted.   In a
narrative full of fabulous characters and brilliant excursions into the unexpected  Michael
Lewis shows us how and why the new baseball knowledge works. He also sets up a sly and
hilarious morality tale: Big Money  like Goliath  is always supposed to win . . . how can we
not cheer for David?
