[AZ Central] Walker allows 1st runs of spring - "Two sliders that I just hung instead of finishing it," Walker said of the homers. He said he was otherwise pleased with the pitch, which he used to strike out C Miguel Montero in the fourth. He said he was able to make adjustments in his delivery to get himself back on track relatively quickly. "Now I know when I’m getting disconnected," he said. "I know when I’m leaking and I knew when my front side is too low. I can actually feel it now and make that adjustment.
