But these details do not touch the main point—Holway’s premise is false because he accepts the conventional mythology about long sequences. He believes that streaks are unbroken runs of causal courage—so that any prolongation by hook or crook is an outrage against the deep meaning of the phenomenon. But extended sequences are no such thing. Long streaks always are, and must be, a matter of extraordinary luck imposed upon great skill. Please don’t make the vulgar mistake of thinking that Purcell or Tversky or I or anyone else would attribute a long streak to “just luck”—as though everyone’s chances are exactly the same, and streaks represent nothing more than the lucky atom that kept moving in one direction. Long hitting streaks happen to the greatest players—Sisler, Keeler, DiMaggio, Rose—because their general chance of getting a hit is so much higher than average. Just as Joe Airball cannot match Larry Bird for runs of baskets, Joe’s cousin Bill Ofer, with a lifetime batting average of .184, will never have a streak to match DiMaggio’s with a lifetime average of .325. The statistics show something else, and something fascinating: there is no “causality of circumstance,” no “extra” that the great can draw from the soul of their valor to extend a streak beyond the ordinary expectation of coin-tossing models for a series of unconnected events, each occurring with the characteristic probability for that particular player. Good players have higher characteristic probabilities, hence longer streaks.

Of course DiMaggio had a little luck during his streak. That’s what streaks are all about. No long sequence has ever been entirely sustained in any other way (the Orioles almost won several of those twenty-one games). DiMaggio’s remarkable achievement—its uniqueness, in the unvarnished literal sense of that word—lies in whatever he did to extend his success well beyond the reasonable expectations of random models that have governed every other streak or slump in the history of baseball.

Probability does pervade the universe—and in this sense, the old chestnut about baseball imitating life really has validity. The statistics of streaks and slumps, properly understood, do teach an important lesson about epistemology, and life in general. The history of a species, or any natural phenomenon that requires unbroken continuity in a world of trouble, works like a batting streak. All are games of a gambler playing with a limited stake against a house with infinite resources. The gambler must eventually go bust. His aim can only be to stick around as long as possible, to have some fun while he’s at it, and, if he happens to be a moral agent as well, to worry about staying the course with honor. The best of us will try to live by a few simple rules: do justly, love mercy, walk humbly with thy God, and never draw to an inside straight.

DiMaggio’s hitting streak is the finest of legitimate legends because it embodies the essence of the battle that truly defines our lives. DiMaggio activated the greatest and most unattainable dream of all humanity, the hope and chimera of all sages and shamans: he cheated death, at least for a while.
