"Diamondbacks infielder Melvin Mora is being given his unconditional release, and the Diamondbacks will make a corresponding move Friday.
"We're just going to move on in a different direction, kind of reshape our bench a little bit," Gibson said. "We'll decide what we want to do on Friday."
Mora, who was batting .228, appeared in 41 games. He signed a one-year, $2.3 million deal in the off-season and was targeted as the starting third baseman.
"It's tough to leave when you're around your family," Mora said. " . . . I was supposed to play third base but (Ryan) Roberts has been playing well. I didn't get playing time at third base, and it's something different, so for me it's hard to get hot. It's difficult when you only play once or twice a week.
"I want to thank the Diamondback organization for giving me an opportunity to be here and I want to thank all my friends and teammates.""
