Campana was hitting just .160 in 51 plate appearances and his speed was neutralized by the fact that he was not able to get on base.
"I've had a rough patch the last couple of weeks," Campana said. "I think it's just getting down there and figuring it out at the plate a little bit. I think that's it. Just start swinging it a little better and hopefully come back."
Marte was hitting .342 with five doubles, a triple, a homer and 11 RBIs for Reno this year.
Last season Marte appeared in 22 games for the D-backs and hit .186.
