Getting 3 batters out in order on nine pitches is one of the most remarkable feats in baseball. Since the late 1800s, only 71 pitchers have been able to do it. Yet, unlike other rare achievements in baseball, such as pitching a perfect game, the "immaculate inning" does not capture the same attention or consideration. In a game that is as unpredictable as baseball, perfection, when it occurs, should be cause for both reflection and celebration. Cairney provides a short history of perfect innings through the stories of the pitchers who pitched them. Beginning with an brief overview of the numbers, the remaining chapters, one for each immaculate inning on record in major baseball, provides insight into the men, their careers and details of the inning itself, from the first recorded perfect inning in 1889 to the most recent string of innings last MLB season in 2014. The names include pitching greats such as Jim Bunning, Sandy Koufax, Nolan Ryan and Randy Johnson, but also many lesser known, if not colourful, pitchers like Sloppy Thurston and Bill Wilson.The teams include famous franchises like the Detroit Tigers and the New York Yankees, but also clubs now defunct like the Boston Beaneaters and the Montreal Expos. Using immaculate innings as benchmarks, the book provides an engaging and entertaining journey through the history of professional baseball that will delight both the serious student of the game, as well as the fan who enjoys reading about the game.
