12:54pm: Jerry Dipoto, Arizona's interim GM since July, will not return to the Diamondbacks organization. Kevin Towers is the team's permanent GM, so Dipoto informed the D'Backs that he'll move on, according to Bob Nightengale of USA Today. Ken Rosenthal of FOX Sports and Nick Piecoro of the Arizona Republic also reported that Dipoto would likely resign (all Twitter links).
Dipoto, 42, was a big league reliever for eight seasons. He spent two of those years with the Mets, one team that could be looking for a GM this offseason. Dipoto, who began the year as Arizona's vice president of player personnel, has interviewed for GM jobs in Seattle and Washington.
