MLBTR's Arbitration Tracker has details on every arbitration eligible player. If the player agreed to terms with his team, we have the dollar amount. If the sides exchanged figures, you'll see both submissions and our automatically-generated midpoint. The tracker allows advanced sorting, so you can narrow your searches by team, signed/unsigned players and whether the case went to a hearing.
As teams and players resolve arbitration cases in January and February, we'll keep the tracker updated with all the information you need to know. Check out MLBTR's Transaction Tracker and Free Agent Tracker while you're at it.
