When I was six, my father gave me a bright-red scorebook that opened my heart to the game of baseball. After dinner on long summer nights, he would sit beside me in our small enclosed porch to hear my account of that day’s Brooklyn Dodgers game. Night after night he taught me the odd collection of symbols, numbers, and letters that enable a baseball lover to record every action of the game. Our score sheets had blank boxes in which we could draw our own slanted lines in the form of a diamond as we followed our players around the bases. Wherever the baserunner’s progress stopped, the line stopped. He instructed me to fill in the unused boxes at the end of each inning with an elaborate checkerboard design which made it absolutely clear who had been the last to bat and who would lead off the next inning. By the time I had mastered the art of scorekeeping, a lasting bond had been forged among my father, baseball, and me.
