“The Computer Solidly Supports The Way Cook Says Baseball Should Be Played”

October 19, 2014 in Books, Excerpts, Science/Tech, Sports | Permalink

Long before Moneyball, Earnshaw Cook was, in Frank Deford’s words, the “scholar-heretic” of baseball, a statistician who proved the game’s strategy was backwards. Many of his innovations are common knowledge in the sport today (e.g., sacrifice bunts are usually unproductive), though others are still strangely not implemented. For instance: If you’re in a pivotal post-season game played under National League rules, why not use a relief pitcher who matches up well with the opposing lineup at the beginning of the game, and then pinch hit for him the first time he’s to bat so that you get an extra plate appearance by a good hitter? Then you can insert your “starting” pitcher. Makes sense. Many other of the stat man’s strategies have been disproven, but his underlying message that the sport was being played more from tradition than wisdom was correct.

Deford profiled Cook in Sports Illustrated for the first time in 1964, and while that piece doesn’t seem to be online, here’s the opening of his 1972 portrait, “It Ain’t Necessarily So, and Never Was,” which ran just prior to the publication of Cook’s Percentage Baseball and the Computer, when the numbers whiz went digital:

For more than a decade Earnshaw Cook, a retired Baltimore metallurgist, has been trying to convince baseball’s bosses that playing the sacred percentages is, to be blunt, dumb baseball. In 1964 Cook brought out a 345-page book, Percentage Baseball, that was full of charts, curves, tables and complicated formulas that sometimes went on for the better part of a page. The book dared to suggest that either: a) baseball is not using the best possible odds on the field, or b) mathematics is a fake.

Nothing has happened since to convince Cook that ‘a’ is wrong and ‘b’ is right. ‘As in the world around us,’ he says, ‘baseball offers a completely balanced, highly complicated statistical system, demonstrably controlled in all its interactions of play by the random operations of the laws of chance. As such, it becomes a fascinating illustration of a process readily susceptible to reliable mathematical analysis. Baseball also furnishes a classic example of the utter contempt of its unsophisticated protagonists for the scientific method.’

That last sentence is Cook’s way of saying that the national pastime thinks he is as nutty as a fruitcake. Since 1964 nobody has dared test out his conclusions even in, say, a winter rookie league. Oh yes, the managers in 1964 were named: Berra, Bauer, Pesky, Lopez, Tebbetts, Dressen, Hodges, Lopat, Rigney, Mele, Kennedy, Hutchinson, Craft, Alston, Bragan, Stengel, Murtaugh, Keane, Mauch and Dark. They all stayed faithful to the memory of Connie Mack—but only Alston is still managing at the same major league shop.

Cook has had some nibbles from the baseball Establishment. The Houston Astros approached him shortly after his book came out and inquired if he thought he could apply his figures in such a way that he could make judgments about minor league prospects. Cook said he would try. He checked the player records Houston sent him, and said that his evaluation indicated the two best prospects were named Jim Wynn and Rusty Staub. This was not bad figuring, as Wynn and Staub are probably still the two best players ever to wear Houston uniforms, but Cook never heard from the Astros again. He also got feelers from the Cubs and Phillies, but nothing came of those.

Ignored, Cook went back to his numbers, and this April his second volume on the subject, Percentage Baseball and the Computer, is scheduled for publication. Basically, it is 207 pages of computer proof that everything he wrote eight years ago was qualitatively correct. Well, not quite everything. The computer has found that Cook’s percentage lineup—with the best hitter leading off, the second best batting second, etc.—is, over a season, 12 runs less effective than the traditional lineup.

Otherwise the computer solidly supports the way Cook says baseball should be played.•

“Who Am I, And Why Would I Be Considered Some Sort Of Expert On Moneyball?”

May 14, 2013 in Books, Excerpts, Science/Tech, Sports | Permalink

At present, there are 13 used copies of Eric Walker’s oddly titled, out-of-print 1982 baseball-themed paperback, The Sinister First Baseman & Other Observations, on sale from Amazon sellers, and the cheapest one, in merely “Acceptable” condition, goes for $104.96. Who, exactly, is Eric Walker and why does he have so much value for so few people?

There were always those who suspected that baseball’s conventional wisdom was not so wise, but in the 1970s, Walker, a Bay Area baseball fan birthed the idea of Moneyball before Sandy Alderson or Billy Beane had entered the game. Even he, however, had an important precursor. From “The Forgotten Man of Moneyball,” Walker’s 2009 Deadspin article, a passage about his inspiration:

But who am I, and why would I be considered some sort of expert on moneyball? Perhaps you recognized my name; more likely, though, you didn’t. Though it is hard to say this without an appearance of personal petulance, I find it sad that the popular history of what can only be called a revolution in the game leaves out quite a few of the people, the outsiders, who actually drove that revolution. 

Anyway, the short-form answer to the question is that I am the fellow who first taught Billy Beane the principles that Lewis later dubbed ‘moneyball.’ For the long-form answer, we ripple-dissolve back in time to San Francisco in 1975, where the news media are reporting, often and at length, on the supposed near-certainty that the Giants will be sold and moved. There sit I, a man no longer young but not yet middle-aged, a man who has not been to a baseball game — or followed the sport — for probably over two decades, but a man who in childhood used to paste New York Giants box scores into a scrapbook, and who remembers, dimly but fondly, such folk as Whitey Lockman and Wes Westrum.

Carpe diem, I think.

With my lady, also a baseball fan of old, I go to a game. We have a great time; we go to more games, have more great times. I am becoming enthused. But I am considering and wondering — wondering about the mechanisms of run scoring, things like the relative value of average versus power. Originally an engineer by trade, I am right there with Lord Kelvin: ‘When you cannot measure it and express it in numbers, your knowledge is of a very meagre and unsatisfactory kind.’ I fiddle with some numbers; but I vaguely remember Branch Rickey’s work, the cover story in Life magazine for Aug. 2, 1950, [ed. note: it was actually 1954 and not a cover story] and think that I may not need to reinvent the wheel. I go to the San Francisco main library, looking for books that in some way actually analyze baseball. I find one. One. But what a one. 

If this were instead Reader’s Digest, my opening of that book would be ‘The Moment That Changed My Life!’ The book was Percentage Baseball, by one Earnshaw Cook, a Johns Hopkins professor who had consulted on the development of the atomic bomb. Today, when numerical analysis of baseball performance is a commonplace, it is hard to grasp how revolutionary, even shocking, were the concepts Cook was developing (Rickey’s work, which had quickly dropped off everyone’s radar, notwithstanding). The book was, and remains, awe-inspiring.•
