The commissioner's office is telling teams for the first time that baseballs must be stored at a uniform temperature after they are delivered from the manufacturer. "The specifications that Rawlings recommends are a 70 degree temperature and 50 percent humidity," baseball senior vice president Joe Garagiola Jr. said Friday. "We have contacted all 30 of the clubs, and they have all confirmed to us that they will all be storing their baseballs in a temperature-controlled facility. We're not going to have humidors everyplace, but every place will be temperature controlled, and so I think there will be a very high degree of uniformity."
