This should make for an interesting handicap. The Arizona Diamondbacks are finally going to install a humidor
which some think will suppress home runs and this scoring by a significant amount. Below are the over/under, average total, and average runs scored results at Chase Field over the last five seasons.
2017: 42-34-7 O/U, avg. total 9.4, avg. rpg 9.95
2016: 50-28-3 O/U, avg. total 9.0, avg. rpg 11.16
2015: 39-35-5 O/U, avg. total 8.4, avg. rpg 9.11
2014: 36-41-4 O/U, avg. total 8.3, avg. rpg 8.98
2013: 34-46-1 O/U, avg. total 8.5, avg. rpg 8.40
“I am very comfortable saying that, with the humidor running at 50 percent and 70 degrees, there will a reduction in home run production at Chase by 25 to 50 percent,” Nathan concluded. “While it would be nice to come up with a more precise prediction, we should not lose sight of the principal takeaway that the installation of a humidor will reduce the number of home runs substantially.”
