9:20pm: The Diamondbacks didn't get a definitive yes or no from Lyle Overbay on their latest contract offer, but the two sides appear to be working toward completing a deal, reports MLB.com's Steve Gilbert. Overbay and the D'Backs are discussing a one-year contract, and GM Kevin Towers is optimistic about their progress.
"I would say it's progressing well, but it's not done," Towers said. "Everything looks good, although it's not a done deal. I'm cautiously optimistic. We still have some things that we have to work through that we're still working through, but nothing's really changed. My gut is he'll still end up coming here."
