Place your finger just about anywhere on a calendar and you can pinpoint the date of a memorable baseball moment: Jackie Robinson's first game, Eddie Gaedel's only game, the sale of Babe Ruth to the Yankees and how a later-day application of the Best Interests of Baseball Clause might have prevented it. These and dozens more are recounted in this book chronicling hallmark days in all 12 months of the year.

From the first no-hitter in modern baseball (maybe) to the deep roots for the first night game in the major leagues, this book paints a detailed narrative of the game's most important moments, told in 31 singular, remarkable days. Covering the long path to integration, the rise of Dominican players in the game and the infamous banning of the splitter, this Advent calendar of the diamond covers baseball from every angle, and every month of the year.
