Major League Baseball front offices began competing to hire sabermetric analysts primarily to gain a competitive advantage by identifying undervalued players and developing more effective strategies through advanced statistical analysis.

The shift was significantly accelerated by the success of the Oakland Athletics under general manager Billy Beane, whose reliance on sabermetrics—popularized by Michael Lewis’s book Moneyball—demonstrated that teams could win consistently by prioritizing metrics like on-base percentage over traditional, less predictive statistics like batting average.12

This trend evolved into an "arms race" as teams sought to capitalize on the massive influx of data generated by modern tracking technologies, such as Statcast. These systems provided unprecedented detail on every aspect of a game, requiring specialized analysts to parse the information and translate it into actionable insights. By 2012, nearly every MLB franchise employed at least one sabermetrician to help navigate this wealth of data, aiming to improve roster construction and on-field performance.1
