In order to measure the impact Coors Field has on scoring, Elias Sports Bureau looked at how many runs the Rockies and their opponents scored in games played at Coors from its opening in 1995 through the '98 All-Star break and compared that with the average number of runs scored in each of the Rockies' road games over the same period. Elias then did the same set of calculations for the other big league parks, excluding the Braves' (the club changed stadiums in that time) and the two expansion teams'. When the stadiums are ranked in order of the percentage difference attributable to the scoring influence of the ballpark, Coors has far and away the greatest impact.
