Spin rate, launch angle, catch probability and other once unfamiliar terms have now become common in baseball’s lexicon. They are also part of the analytics revolution that has overtaken the sport.

As the Major League Baseball playoffs provide gripping entertainment, the decisions being made by managers are often predetermined and scripted based on analytics. While the Boston Red Sox and Houston Astros battle in the American League Division Series, and the Los Angeles Dodgers and Milwaukee Brewers contend for the National League pennant, computer algorithms will perhaps have as much to do with the outcomes of both series as any human in uniform.

Gone are the days of managers such as Sparky Anderson, Jimmy Leland and Dusty Baker, who would call on countless hours of experience to make extemporaneous moves based on gut feelings, knowing their players’ moods and the rhythm of the moment. Now, mounds of quantitative data rule the day, creating an old school versus new school debate that is being won by people who in many cases have never worn a pair of spikes but have advanced degrees in mathematics.

Throughout front offices of every franchise are expansive analytics departments that frame respective paradigms on building the minor and major league systems. The discipline has provided jobs and power to decision makers who have little or no bona fides playing baseball.

But analytics is not exclusive to baseball. Most if not all NBA franchises and a plurality of those in the NFL have also adopted analytics as the predominant methodology. Yet, there remain many traditionalists opposed to its prevalence.

“The game is a [expletive] joke because of the nerds who are running it,” said Hall of Fame pitcher Goose Gossage in a 2016 interview. “I’ll tell you what has happened, these guys played Rotisserie baseball at Harvard or wherever the [expletive] they went, and they thought they figured the [expletive] game out. They don’t know shit.”

When the Red Sox’ Jackie Bradley Jr. blasted a grand slam off the Astros’ closer Roberto Osuna in the eighth inning in Game 3 of the ALDS Tuesday night to give his team a 2-1 series lead, few if any of the Sox faithful fan base attributed it to analytics as the outfielder touched home plate.

But rest assured, someone in the Sox organization was feverishly working to justify the moment as an analytics success.
