[Updated @ 11:18am: Astros, Reds, Phillies]: News of arbitration [non-]offers are trickling in, so whenever I hear something new I'll add it here. If you discover any on your own don't hesitate to include them in the comments, but be sure to provide a source. I'll update this list accordingly. I am only going to include Type A and Type B free agents, since the arbitration status of unranked players is inconsequential.
Players who were offered arbitration are listed in bold green (Type A) or green (Type B).
Players not offered arbitration are listed in bold red (Type A) or red (Type B).
