With outfielder Ender Inciarte expected to be activated off the concussion disabled list Friday, which probably would have ticketed Campana for Triple-A anyway, the team decided to do it Thursday and have an extra pitcher -- Matt Stites -- in the bullpen.
"He's been a guy that's been there in Triple-A when we needed him, and we have confidence in him in that role," D-backs manager Kirk Gibson said of Campana.
Prior to his game-winning hit, Campana had just one hit in his previous 42 big league at-bats.
"I emphasized to him hitting the ball on the ground more," Gibson said of his meeting Thursday with Campana. "Right now, if you watch how everyone bunt defends people, they come way, way in and it really opens up that 5-6 hole for him, so if he could learn to get it down there, it would put a lot of pressure on them."
