Bill James introduced a formula for estimating a teams expected winning percentage in the major leagues based on the number of runs they scored and allowed. Our preseason team rGS ratings are an average of the teams starting pitcher rGSs, weighted by the individual pitchers projected starts in FanGraphs depth charts. Predicting head-to-head outcomes is a common theme in many sports. Note that one pitcher may have a higher overall rGS than another pitcher but a smaller team rating adjustment; this generally means that his team has a better rotation aside from him, or that he started more games (and thus, his game scores contributed more to the teams rGS). Baseball game predictions. We're using an Elo-based system that also accounts for starting pitchers, travel distance and rest, with an average team rating of about 1500.
