"It's a good wakeup call," Campana said. "It's fun, though, every time. Anytime you can come up here it's exciting, so it's good to be here."
Campana got to Memphis around 3 a.m. and then caught a 10 a.m. flight to Los Angeles, hopping in a cab and arriving at Dodger Stadium just in time for batting practice.
"I'll just do what I can do every day, just see if I can have a little spark for as long as I'll be here," Campana said. "It could be a very short time. Just win a few games while I'm here."
Campana started the year with the D-backs and hit .160 in 51 plate appearances before being optioned to Reno on May 2. While with Reno he hit .286.
"I think the big thing is I felt OK at the plate when I left here," Campana said. "I felt like I was hitting the ball all right, just kind of hitting the ball at people. I was able to find some holes down there and anytime you're finding holes, your confidence gets up and that seems to keep going."
