Earnshaw Cook

Earnshaw Cook (born March 28, 1900 in Reisterstown, Maryland - died November 11, 1987 in Baltimore, Maryland) was an early researcher and proponent of sabermetrics, the analysis of baseball through statistical means.

Engineering

A member of the Princeton University class of 1921, Cook was an engineer specializing in metallurgy.cite book| last = Schwarz |first = Alan |authorlink = Alan Schwarz |title = The Numbers Game: Baseball's Lifelong Fascination with Statistics |isbn = 0312322224 |publisher = Thomas Dunne Books |location = New York | year = 2004 |pages = p. 76 | url = http://sports.espn.go.com/mlb/columns/story?columnist=schwarz_alan&id=1835736 |accessdate=2008-01-20] He spent most of his working life at the American Brake Shoe Co. in Mahwah, New Jersey, later consulting on the Manhattan Project before retiring from the industry 1945. In the 1950s and 1960s, Cook worked as a mechanical engineering professor at Johns Hopkins University, where he published several academic papers.cite book |title= Does Measurement Measure Up?: How Numbers Reveal and Conceal the Truth | last = Henshaw |first = John M. |isbn = 080188375X |publisher = Johns Hopkins University Press |year = 2006 |pages = p. 73]

tatistical baseball studies

Cook first set about his statistical baseball studies with the goal of proving that Ty Cobb, holder of the highest career batting average at .366, was better than Babe Ruth, the premier power hitter of the first half of the 20th century. Additionally Cook sought to understand strategical issues such as batting order and relief pitching, rather than accept the traditional strategies of baseball.Schwarz, p. 72.] "Sports Illustrated" writer Frank Deford learned of Cook's work and interviewed him for the lead story of a 1964 issue with the title "Baseball is Played All Wrong". [cite journal |last=Deford |first=Frank |authorlink=Frank Deford |date=1964-03-23 |title=Baseball Is Played All Wrong |journal=Sports Illustrated |volume=20 |issue=12 |pages=14–17 |id= ] Using tools of the time, such as a slide rule and a Friden STW mechanical calculator, Earnshaw Cook published the culmination of his work, "Percentage Baseball" (MIT Press), in 1964.Schwarz, p. 78.] "Percentage Baseball" was the first book of baseball statistics studies to gain national media attention.cite book| last= Albert |first = James | coauthors = Jay M. Bennett |title = Curve Ball: Baseball, Statistics, and the Role of Chance in the Game |isbn = 0387988165 |year = 2001 |pages = p. 170-171 |publisher = Springer] Though Cook received some support from Los Angeles Dodgers manager Walter Alston and Chicago White Sox owner Bill Veeck, most baseball executives and managers rejected Cook's mathematical approach and academic language.Schwarz, pp. 77-78.] He was also criticized for lax mathematical models and inadequate numerical evidence by statisticians, such as George Lindsey (himself a baseball statistician), who advised that it be "kept out of the sight of students of the theory of probability."cite journal |last = Lindsey |first = George |authorlink = George Lindsey (statistician) |year = 1968 |title = The Analysts' Bookshelf: Review - Percentage Baseball|url = http://links.jstor.org/sici?sici=0030-364X%28196809%2F10%2916%3A5%3C1088%3APB%3E2.0.CO%3B2-9 |journal = Operations Research |pages = pp. 1088–1089 |volume = 16 |issue = 5 | month = Sep. - Oct.] Modern author Michael Lewis describes Cook's prose as "crafted to alienate [baseball statistics] converts."cite book|last = Lewis |first = Michael |authorlink= Michael Lewis (author) |title = Moneyball: The Art of Winning an Unfair Game |isbn = 0393057658 |year = 2003 |publisher = W.

Among Cook's most bold assertions was that, utilizing his strategies, a team could gain up to 250 runs a season, a number which modern methods indicate is an extreme overestimate. Years later, sabermetrician Pete Palmer and sports historian John Thorn asserted that their computer simulations using Cook's lineup modifications actually slightly reduce the number of runs a team scored.cite book|last = Dierker |first = Larry |authorlink = Larry Dierker |title = My Team: Choosing My Dream Team from My Forty Years in Baseball |isbn = 0743275144|year = 2007 |pages=pp. 228-229 |publisher = Simon & Schuster ] Bill James would later write in his "1981 Baseball Abstract" that "Cook knew everything about statistics and nothing at all about baseball--and for that reasons, all of his answers are wrong, all of his methods useless."Bill James as quoted by cite web |title = Abstracts From The Abstracts: Part Five: 1981 Baseball Abstract |url = http://baseballanalysts.com/archives/2004/08/abstracts_from_16.php |accessdate=2008-01-20 |last = Lederer |first = Rich |date=2004-08-02 |work = Baseball Analysts] Earnshaw Cook also dismissed the effects of player handedness (thusly, condemning the use of the platoon system), which even contemporary studies pointed out to be erroneous.cite journal |last = Hooke |first = Robert |title = Book Review - Percentage Baseball |journal = Journal of the American Statistical Association |volume = 62 |issue = 318 |month = June |year = 1967 |pages = pp. 688–690 |url = http://links.jstor.org/sici?sici=0162-1459%28196706%2962%3A318%3C688%3APB%3E2.0.CO%3B2-2 |accessdate=2008-01-20] Cook did, however, uncover several important pieces of information which are now accepted as common knowledge in modern sabermetrics, such as the inefficiency of the sacrifice bunt.cite book |title = The Cooperstown Symposium on Baseball and American Culture, 2001 |editor = William M. Simons, Alvin L.

Influence and legacy

Cook never worked for a Major League baseball team; he described the relationship between himself and baseball franchises in the forward to "Percentage Baseball": "I would be willing to go as far as pretending to understand why none of four competent and successful executives of second-division ball clubs were most reluctant to employ probabilistic methods of any description... but they did not even want to hear about them!"cite web|url = http://espn.go.com/mlb/columns/neyer_rob/1456664.html |last = Neyer |first = Rob |authorlink=Rob Neyer |accessdate=2008-06-25 |title = Sabermetricians slowly being added to the inner circle |work = ESPN.com ] Though Cook himself was never hired by a Major League team, his work influenced Major League Baseball personnel such as Tal Smith, Ewing Kauffman and Davey Johnson, as well as future sabermetricians like Palmer.Schwarz, pp. 82-83.] "Percentage Baseball" also influenced Eric Walker, who worked for the San Francisco Giants and Sandy Alderson's Oakland Athletics. Cook's slide rule, which he used during his research for "Percentage Baseball", was donated upon request to the Baseball Hall of Fame.Schwarz, p. 83.] Earnshaw Cook died of a heart attack in 1987.

Philip Roth based the character of the kid genius baseball coach Isaac Ellis in "The Great American Novel" on Cook.cite news| title= The Buffett of Baseball| url = http://www.newyorker.com/archive/2002/09/23/020923ta_talk_surowiecki |accessdate=2008-01-20 |last = Surowiecki |first = James |authorlink = James Surowiecki |date = 2002-09-23 |work = The New Yorker ] cite news| url = http://www.mtstandard.com/articles/2008/01/13/entertain_books/hjjdiiibhggeji.txt |accessdate=2008-01-20 |title = Many faces of Philip Roth |work = The Montana Standard |date=2006-11-18 |last = Thompson |first = Bob]
