"I had that one tough inning where I wasn't gripping it the way I should," Matusz said. "I kind of got out of the groove at the same time, but I was able to manage with it and get through that tough inning."
Ray issued one walk in one inning, but he stranded the runner during an injury rehabilitation assignment for the Baysox.
