Haniger, who can play center field, is regarded as a patient hitter with decent speed, and he has power potential. He was the 38th overall pick in the 2012 First-Year Player Draft and was a member of the Arizona Fall League's Top Prospects Team last year.
Banda, who turns 21 in a couple of weeks, has appeared in 20 games (14 starts) for Class A Wisconsin and was 6-6 with two saves and a 3.66 ERA.
Parra was hitting .259 for the D-backs this year. He hit .274 and won a pair of Gold Glove Awards during his six seasons in Arizona.
"I try not to think anything about it because I'm happy being here," Parra said prior to Wednesday's game. "I'm happy being with the Diamondbacks. But that's baseball. Today you play and tomorrow you could play for another team. But I don't want to think about it and put pressure on myself. I'm going to play hard today and play to win."
