Who hit the most homers?

Since the installation and discovery of the humidor in Coors Field, runs and high scoring games have since gone down in frequency. The Rockies do not deny this, however they point to the reason for balls flying out of Coors Field is not so much the altitude (5,280 feet above sea level), but the extremely dry air in Denver. They liken it to playing baseball with golf balls, as harder objects travel faster than softer objects when hit, like a baseball when kept at a humidity level recommended by the manufacturer. Columnists in Denver's newspapers also speculate that most players are stopping the use of steroids because of the increased testing and penalties, so fewer home runs are hit at Coors Field.
