第一章：量化之問——為何要測量棒球？

Chapter 1: The Question of Quantification — Why Measure Baseball?

為什麼我們要將一場棒球比賽拆解成數字？當一位投手投出 95 英里的快速球，當打者將球擊向左外野的全壘打牆，當看台上的觀眾在那一瞬間屏息、繼而爆發出吼叫——這一切都充滿了難以言傳的美感與戲劇張力。然而，自十九世紀中葉以降，人類開始用另一種方式「觀看」棒球：他們將擊球、跑壘、接殺、防守化為一行行數字與比例。這並非單純的記錄癖好，而是一場深刻的知識革命。它改變了我們理解運動的方式，最終也改變了我們理解人類決策、評價勞動、衡量價值的方式。本書的核心問題由此而生：量化棒球究竟意味著什麼？它帶來了什麼，又犧牲了什麼？

*Why must we reduce a baseball game to numbers? When a pitcher delivers a 95-mile fastball, when the batter launches the ball toward the left-field wall, when the crowd holds its breath and then erupts—the moment is saturated with an aesthetic and dramatic intensity beyond words. Yet since the mid-nineteenth century, humanity has begun to "watch" baseball in a fundamentally different way: by recording hits, base-running, putouts, and defense as rows of figures and ratios. This is no mere archival hobby; it is a profound intellectual revolution. It has reshaped how we understand sport, and ultimately how we evaluate human decision-making, labor, and worth. From this question the book takes its central concern: What does it mean to quantify baseball? What does quantification gain, and what does it sacrifice?*

1.1 棒球的雙重傳統：敘事之球與統計之球 / Baseball's Dual Tradition: Narrative Ball and Statistical Ball

若想理解量化棒球的源頭，我們必須先承認一件常被忽略的事實：棒球從誕生之初，便同時擁有兩條相互糾纏卻又彼此對立的傳統。第一條是敘事傳統——棒球作為美國之夢的具象化身，作為英雄、神話與集體記憶的載體；第二條則是統計傳統——棒球作為可被測量、可被分析、可被比較的對象，作為數字背後隱藏規律的競技場。這兩條傳統從未真正分家，但量化革命的本質，正是讓第二條傳統逐漸從邊緣走向中心，從輔助敘事走向重塑敘事。

*To understand the origins of baseball quantification, we must first acknowledge an often-overlooked fact: from its very inception, baseball has carried two intertwined yet opposing traditions. The first is the narrative tradition—baseball as the concrete embodiment of the American Dream, as a vessel for heroes, mythology, and collective memory. The second is the statistical tradition—baseball as an object that can be measured, analyzed, and compared, as an arena where numbers reveal hidden regularities. These two traditions have never truly separated, but the essence of the quantification revolution is precisely the gradual movement of the second tradition from the periphery to the center, from supporting narrative to reshaping it.*

1.1.1 阿布納·道布戴的發明神話與敘事之球的奠基 / Abner Doubleday's Invention Myth and the Foundations of Narrative Ball

十九世紀的棒球敘事傳統，在很大程度上由一則神話所塑造。1905 年，受美國參議員指定的「米爾斯委員會」(Mills Commission) 宣佈，棒球是由內戰英雄阿布納·道布戴 (Abner Doubleday) 於 1839 年在紐約州庫珀斯敦 (Cooperstown) 所發明。儘管這一說法在歷史學界早已被推翻——多項研究顯示，類似的球類遊戲在英國與北美殖民地早已存在——但這則故事之所以歷久不衰，正是因為它符合美國需要的神話結構：一個純粹源自美國土壤、由一位民族英雄發明、承載民主與機會精神的運動。

*The narrative tradition of nineteenth-century baseball was shaped to a great extent by a myth. In 1905, the Mills Commission, appointed by U.S. senators, declared that baseball had been invented in 1839 by Civil War hero Abner Doubleday in Cooperstown, New York. Although this account has long been discredited by historians—numerous studies have shown that similar ball games existed in Britain and colonial North America—the story endured precisely because it fit the mythological structure America needed: a sport purely born on American soil, invented by a national hero, embodying democracy and opportunity.*

這種敘事的力量極為強大。1903 年，《紐約晚郵報》(New York Evening Mail) 體育記者佔據了一個新的「國家的舞台」(national stage)，美聯 (American League) 與國聯 (National League) 簽署了第一份國家協議 (National Agreement)，世界大賽 (World Series) 正式誕生。從此，每年的秋季不僅是球季的尾聲，更是一則關於城市、階級、英雄與反英雄的史詩。波士頓紅襪的「貝比魔咒」(Curse of the Bambino)、喬·迪馬吉奧 (Joe DiMaggio) 的 56 場連續安打、漢克·阿龍 (Hank Aaron) 打破貝比·魯斯全壘打紀錄時所承受的種族主義威脅——這些都是敘事之球的經典母題 (motif)，它們的力量不在於數字本身，而在於數字所承載的人類故事。

*The power of this narrative was enormous. In 1903, the New York Evening Mail occupied a new "national stage," and the American League and National League signed their first National Agreement, formally inaugurating the World Series. From then on, every autumn was not merely the end of a season but an epic of cities, classes, heroes, and anti-heroes. The Boston Red Sox's "Curse of the Bambino," Joe DiMaggio's 56-game hitting streak, Hank Aaron's reception of racist threats as he broke Babe Ruth's home run record—these are the classic motifs of narrative ball. Their power lies not in the numbers themselves but in the human stories the numbers carry.*

1.1.2 亨利·查德威克與統計之球的誕生 / Henry Chadwick and the Birth of Statistical Ball

然而，在敘事之球壯大之際，另一種觀看棒球的方式也在悄悄成形。它的奠基者，是一位從英國移民至紐約的記者——亨利·查德威克 (Henry Chadwick, 1824–1908)。查德威克原是板球記者，1850 年代將這項英國運動的統計傳統帶入美國，並在 1859 年設計出第一張標準化的「打擊紀錄卡」(box score)。這張卡片將一場九局的比賽壓縮成幾行數字：每個球員的打數、安打、得分、失誤、三振、保送——每一個今天棒球統計表上的基礎欄位，都源自查德威克最初的設計。

*Yet as narrative ball expanded, another way of watching baseball was quietly taking shape. Its founder was a journalist who had emigrated from England to New York—Henry Chadwick (1824–1908). Originally a cricket reporter, Chadwick brought the statistical tradition of that English sport to America in the 1850s, and in 1859 he designed the first standardized box score. This card compressed a nine-inning game into a few rows of numbers: at-bats, hits, runs, errors, strikeouts, walks for each player. Every basic column on today's baseball stat sheet derives from Chadwick's original design.*

查德威克的動機並非要把棒球「數字化」，而是要解決一個具體的職業問題：他希望為《紐約剪報》(New York Clipper) 報紙撰寫出更精確、更有資訊量的比賽報導。在他看來，數字是語言的延伸，是幫助讀者在腦海中「重建」比賽的工具。這種思想——測量作為理解的中介 (measurement as mediation of understanding)——構成了後來整個量化棒球傳統的哲學起點。

*Chadwick's motivation was not to "digitize" baseball, but to solve a concrete professional problem: he wanted to write more accurate and informative game reports for the New York Clipper. In his view, numbers were an extension of language, a tool for helping readers mentally "reconstruct" the game. This idea—measurement as the mediation of understanding—constitutes the philosophical starting point of the entire later tradition of baseball quantification.*

1.1.3 兩條傳統的交織與張力 / The Interweaving and Tension of the Two Traditions

敘事之球與統計之球在歷史上從未真正分開。事實上，它們經常互相滋養：敘事需要數字來提供細節與權威感，數字也需要敘事來賦予意義。當我們說「貝比·魯斯在 1927 年敲出 60 支全壘打」時，我們不僅在陳述一個統計事實，更在召喚一個關於「偉大」的敘事框架。當我們說「迪馬吉奧連續 56 場比賽有安打」時，我們不僅在引用一個數字，更在邀請讀者進入一段關於堅持、孤獨與時代精神的史詩。

*Narrative ball and statistical ball have never truly separated in history. In fact, they have often nurtured each other: narrative needs numbers for detail and authority, while numbers need narrative to acquire meaning. When we say "Babe Ruth hit 60 home runs in 1927," we are not merely stating a statistical fact but invoking a narrative framework of "greatness." When we say "DiMaggio had a 56-game hitting streak," we are not merely citing a number but inviting the reader into an epic about perseverance, solitude, and the spirit of an era.*

然而，當這兩條傳統走向量化革命時，張力便不可避免地浮現。純粹的敘事者會說：「數字冰冷，無法捕捉棒球場上那一刻的激情與偶然。」純粹的統計者則反駁：「沒有數字，我們就只能依靠記憶與偏見，而記憶與偏見正是棒球決策最大的敵人。」本書的一個核心論點是：這兩種立場並不必然對立，但它們確實代表了兩種不同的真理觀 (conceptions of truth)——一種是敘事真理 (narrative truth)，即「這件事確實如此發生過並且意義重大」；另一種則是測量真理 (measurement truth)，即「這件事可以被重複驗證並用於預測」。

*However, when these two traditions encounter the quantification revolution, tension inevitably surfaces. The pure narrative voice will say: "Numbers are cold; they cannot capture the passion and contingency of a moment on the baseball diamond." The pure statistical voice will retort: "Without numbers, we are left only with memory and bias, which are the greatest enemies of baseball decision-making." One of the central arguments of this book is that these two positions are not necessarily opposed, but they do represent two different conceptions of truth—one is narrative truth, the claim that 'this thing happened and matters,' and the other is measurement truth, the claim that 'this thing can be repeatedly verified and used for prediction.'*

這兩種真理觀的張力，正是後續章節將反覆探討的核心辯證。我們將看到，當比爾·詹姆斯 (Bill James) 在 1970 年代開始撰寫《棒球摘要》(Baseball Abstract) 時，他所挑戰的正是敘事之球對棒球理解的壟斷；他主張，棒球不是故事的集合，而是一個可被拆解的系統——一個由無數微小決策所組成的因果網絡。但我們也將看到，當統計學家在二十一世紀試圖完全用數字取代敘事時，他們同樣遭遇了反彈：球迷依然需要英雄，依然需要故事，依然需要那些「無法被量化的瞬間」。

*The tension between these two conceptions of truth is the central dialecti
