"The MRI [on Tuesday] was unchanged since April, so he will come in for treatment on Thursday and hope he's ready to go on Friday," manager Buck Showalter said. "That's what we were kind of expecting."
Hardy, who hasn't played since Friday, will be shut down for about 48 hours, and the Orioles remain optimistic that they've gotten out in front of the issue. He missed six games in April, including five straight, with lower back spasms.
