Coors Field has become somewhat less of a hitter’s paradise since the Rockies began storing baseballs in a humidor and Dave Krieger of the Denver Post reports that they hope to deflate the ridiculous offensive numbers being posted at Triple-A by doing the same in Colorado Springs.
In general the Pacific Coast League is very hitter-friendly, but Colorado Springs takes that to an extreme. Security Service Field is 6,531 feet above sea level, which is the highest elevation of any ballpark in professional baseball, and this season the pitching staff there had a combined 6.41 ERA.
It’s nearly impossible to develop pitching prospects in that environment and even getting an accurate sense of hitting prospects’ abilities is difficult. Former first-round pick Greg Reynolds, who spent most of the season at Triple-A, told Krieger that “the ball doesn’t really do what it’s supposed to do there” and “without even knowing it, you’re trying to do something a little different just to make the ball do what it’s supposed to do.”
In some sense there’s an advantage to be gained in preparing Triple-A prospects to play in the majors’ most hitter-friendly ballpark, but Colorado Springs is still going to be very hitter-friendly with a humidor or not and deflating the numbers a bit should help the pitchers focus more on development rather than simply not getting their brains bashed in.
