According to this article in NewsOK.com , the Humidifier was a failure from the beginning, contrary to what the full-time nut case and part time sports reporter for the Denver Post, Troy E. (the “E” is for ) has been vociferously claiming for years:
Rockies’ experiment with baseballs backfires
By Bill Sones and Rich Sones, Ph.D.
Strange but True
Q:What was the point of the Colorado Rockies baseball team placing balls in a high-humidity chamber for several months before games? Were they trying to cheat?
A:It was actually done in the name of fair play, New Scientist magazine says. The Rockies play in high-altitude Denver, where the thin air means batted baseballs travel up to 20 feet farther than at sea level. So, the humidity chambers were an attempt to tame down the overexuberant orbs. Then a team of University of Colorado researchers reported that the Rockies may have gotten things backward: Moisture may make the balls fly even farther. They found that two months in humidity of 30 to 50 percent increased the diameter of the balls by 0.24 percent and their mass by 1.6 percent. While it’s true the bigger, heavier, “squishier” balls come off the bat slightly more slowly and experience more drag, the extra mass more than compensates for these effects as the balls “take longer to decelerate,” and so carry farther. Moreover, the moist balls are harder for pitchers to curve and thus easier for sluggers to hit.
This proves, once and for all, what the Baseball Observer has said from the very beginning: there is no scientific or empirical evidence that storing baseballs in a humidifier makes the slightest bit of difference, except, obviously the psychological one.
