Rickey continued to innovate in his time with Brooklyn. He was responsible for the first full-time spring training facility, in Vero Beach, Florida, and encouraged the use of now-commonplace tools such as the batting cage, pitching machines, and batting helmets. He also pioneered the use of statistical analysis in baseball (what is now known as sabermetrics), when he hired statistician Allan Roth as a full-time analyst for the Dodgers in 1947. After viewing Roth's evidence, Rickey promoted the idea that on-base percentage was a more important hitting statistic than batting average. While working under Rickey, Roth was also the first person to provide statistical evidence that platoon effects were real and quantifiable.
