The Arizona Diamondbacks have made a contentious effort to try and stay away from salary arbitration hearings with their players. For the most part they have been successful. In the past decade the team has been able to sign all of their players before the scheduled arbitration hearing date.
There have been times when it went down to the wire such as the recent contract with Conor Jackson which was hammered out just before the start of the hearing. It is in the best interest of the player and the team to try and avoid arbitration hearings.
