Baseball's Creeping Math Problem


Image result for baseball stats

I started reading Smart Baseball  by Keith Law, about the nature of player evaluation in baseball. Keith works with teams to evaluate performance and help big league teams win more. He’s loves numbers and comparisons and telling us how little we understand the game. He comes off a little stuffy with his 'well actually' deep dives into historic players and old statistical measurements. He’s mostly good natured though, and it’s hard not be convinced that these newer sabermetric figures are the most efficient ways to compile stats. 

I’m a bit old fashioned on sports, I enjoy the sport first and consider the numbers second. Mostly I don’t think about them. I don’t gamble or play fantasy baseball so individual stats are important as a measuring stick for historical comparison and salary. I follow teams and then players. I realize having statistically better players means you team is more likely to win, but it doesn’t mean I want to slice numbers thinner than a deli counter prosciutto. Smart Baseball isn’t a book full of cheery anecdotes and life lessons from a former executive. It’s more like a textbook, informational and straightforward.

 The thesis is really this: as a measure of value to a team, the old statistics should be phased out. If the purpose is for managers, owners, scouts and sportswriters to assign values to players, sabermetrics are perfect. The data says so at least. I think at least some portion of this is slick graphs and quirky player FYIs. But I’m willing to listen. Baseball elders did the best they knew how with available data at the time. We watch a more precise game now. Everything is tracked and nerds create new ways to map player contributions.

The much criticized statistics (batting average, RBI) at least had broad appeal. Fans and scouts knew how to score players and assign value. Newer stats like WAR (wins above replacement) and wOBA (weighted on base average) are certainly more precise but, for now, don’t have broad appeal.

 A guy named Bill James created efficient measures of performance in the late 70s. We call them sabermetrics and most clubs have come around to his way of thinking. Acceptance takes time though and just because someone comes up with a brilliant system doesn’t mean everyone will be on board. Reluctance to change doesn’t equate to stupidity or arrogance, it just means this ‘thing’ needs more time.

Sabermetrics provide value where no one knew to look before. But they risk becoming an end to themselves unless the baseball continues to draw sharp lines around their product. They should allow changes to the game on the margins and phase everything in slowly. The NFL created additional problems by trying to redefine things like catches, holding and pass interference. The multiple camera angles create the need for more precise rules on those very things we are trying to determine. It’s a vicious cycle and not one that gets resolved easy.

The MLB is a slow moving body, like an Alaskan glacier or the U.S. Senate. This is a good thing. It ensures consistency. If it lets the stats wonks change everything we track, it won’t be long before the fun is gone. Mangers will manage purely on numbers and forget how to take chances. Players won’t take chances at the plate on a first pitch strike if the percentages are bad. It could be a lab experiment, a test between each team’s mathematical models. Too boring for average fans.

 Every team needs wins. Wins come from runs. Runs come from more opportunities to score. Yes, I realize I’m summarizing the Jonah Hill explainer from Moneyball but stay with me. By valuing certain aspects of the game over others (OBP over AVG) clubs can scoop up wins they might not otherwise have gotten using traditional measures of performance. Moneyball and the A’s are just the most high profile example of this thinking. Wonkish number crunchers who follow baseball have been doing this for years, creating their own statistics I mean.

More competitive teams mean fan participation goes up. (No I didn’t create a graph for that but it stands to reason right?) Clubs sell more tickets and merchandise with a winning team in town. All this comes with a lot of caveats and side bars but winning or at least the chance of winning trumps loosing. What does the game look like in 20 years if managers utilize shifts on defense for every opposing batter and mix up the pitching rotation to devalue the closer? It might turn baseball into America’s favorite sport again, but it could also make it a total bore.

I watched a Netflix special the other night on the origins of curling. It closer to amatuer bowling in the eighties, guys from the local club meeting for beers. Apparently one of the best players found a loophole in the scoring and exploited it to countless Brier victories. The problem was it kept scoring so low and turned the whole affair into a colossal bore that fans started booing them everywhere they went. The sport instituted some rule changes to prevent low scoring games (matches?) and bring back the fans. 

I think there is a lesson in there for baseball. Make changes where necessary but be deliberate please. Too much too soon and the already dwindling fan base goes away for good. Don’t change the nature of the sport and don’t assume statistics that are practical and quantifiable will be embraced by everyone.

The average age of baseball fans is 57. So they have a problem every sport suffers with, how to attract new fans while not alienating the regulars. Don't let the math overwhelm the talent.
