It’s tonight at midnight. Reportedly, the Braves will offer arbitration to Drew and Wright, but not Byrd or Ortiz. They’re negotiating with Byrd to re-sign him, so we’ll know about his future with the club in the next few hours, probably.
Not mentioned is Julio Franco, but I assume that the Braves will do what they have in the past, offer him arbitration then sign him to a minor-league deal later in the process (if he can’t latch on with a major league deal elsewhere).
This doesn’t affect players not eligible to file for free agency. The deadline to tender contracts to them is December 20. I haven’t heard one word on if the Braves might nontender someone. (I thought Reitsma and possibly DeRosa would be let go.)
