Maurer threw a perfect inning in Wednesday's spring training loss to the Royals.
The outing brought the 26-year-old's ERA down to 3.00 through six Cactus League innings. Carter Capps (elbow) was expected to compete with Maurer for the Padres' closer role this spring, but the former has yet to make an appearance, while the latter has done nothing to relinquish the role. It looks like the veteran pitcher has a firm grasp on the job heading towards Opening Day.
