Maurer will be on the Padres' Opening Day roster, Jeff Sanders of the Union-Tribune reports.
The hard-throwing right-hander started out this spring with his sights set on potentially landing a spot in the rotation, but the Padres have instead to keep him on the active roster in a bullpen role. Maurer can reach the mid-to-high 90's and he's historically been able to keep the ball in the park, but he's allowed five home runs this spring after giving up just three big flies all of last season. If he can up his strikeout rate (6.9 K/9 in 2015), he'll be a valuable member of the Padres bullpen. That said, Kevin Quackenbush is likely ahead of him in the pecking order if closer Fernando Rodney struggles.
