Pennant races are arguably the most important aspect of baseball. Players, teams, and franchises are all after one goal: to win the pennant and get into the post-season. But what really determines who wins? Statistical analyses of baseball abound: different ways of breaking down everyone’s individual performance, from hitters and pitchers to managers and even owners. But surprisingly, team success-what makes some teams winners over an entire season-has never been looked at with the same statistical rigor. In It Ain’t Over ’Til It’s Over, The Baseball Prospectus Team of Experts introduce the Davenport Method of deciding which races were the most dramatic-the closest, the most volatile-and determine the ten greatest races of modern baseball history. They use these key races (and a few others) to answer the main question: What determines who wins? How important are such things as mid-season trades, how much a manager overworks his pitchers, and why teams have winning and losing streaks? Can one player carry a team? Can one bad player ruin a team? Can one bad play ruin a team’s chances? This fascinating and illuminating book will change your perception of the game.
