"We've had a lot of off-days this month, and we've played in some real tough conditions, and I just wanted J.J. to get off good, stay healthy," Showalter said. "He's a big part of [our team]. There's a lot of things that are affected if he has a physical issue. We try to overcome, but trying to do it before an off-day gives him two. It's going to be a challenging road trip, like they all are — especially this one. But I tried to do it before the off-day."
