Walker was a National Public Radio correspondent in the early 1980s when he began filling the San Francisco airwaves with his theories regarding baseball — specifically, that on-base percentage was undervalued, fielding was misunderstood and power ruled all. One increasingly intrigued listener was Sandy Alderson, then a young Athletics executive, who soon hired Walker as a team consultant and with him devised the Oakland philosophy now called Moneyball.
As Walker’s website, the increase in baseball’s power factor has occurred gradually over the past 100 years with only two significant :
Walker found two substantial and essentially permanent jumps. First was the 1920s, because of the introduction of a livelier ball and the sport’s Babe Ruth-inspired embrace of slugging. The second was in 1993 and 1994, when P.F. suddenly leapt 7 percent to about 1.6, where it has since settled. Walker contends that such a jump is far more indicative of a change made to the ball — which Major League Baseball has long denied — than a steroid power boost, which would have produced an effect far more gradual as the decade progressed.
Thus continues the debate of the effects of steroids on baseball statistics.
