PITTSBURGH -- Construction on the humidor at Chase Field is progressing, and the team could begin using balls stored in there in about a month.
Once the construction is complete, the humidor will be tested by University of Massachusetts Lowell to make sure it is in compliance. Then balls will need to be stored in the humidor for two weeks before being used.
"No ball is allowed to be brought out unless it's been there for two weeks," GM Mike Hazen said. "And if they come out and don't get used they have to go back in there.
