The Scourge of ‘Win Probability’ in Sports

To watch baseball or any other sport is to confront the fundamental unpredictability of the universe, its utter refusal to bend to your wishes, no matter how fervent. In recent years, some broadcasters have sought to soothe this existential uncertainty with statistics. This season, ESPN announced that a special graphic would appear on all of its Major League Baseball telecasts. In the upper-left corner of the screen, just above the score, each team’s chance of winning the game is expressed as a percentage—a whole number, reassuring in its roundness, that is recalculated after every at-bat. Its predictions may help tame the wild and fearful id of your fandom, restricting your imagination of what might happen next to a narrow and respectable range.

You might think that so insistently reminding fans of their team’s “Win Probability” would be against, could make an early bedtime more enticing. The producers of reality shows such as know this, which is why they use quick cuts and split screens to deceive fans into thinking that teams are closer than they really are, and that the outcome is less certain than it really is. But ESPN has a more evolved consumer in mind. We got a clue as to who this person might be in March, when Phil Orlins, a vice president of production at the company, previewed the graphic. Orlins said that Win Probability would speak “to the way people think about sports right now,” especially people “who have a wager on the game.”
