On Tuesday, the seven unsigned Orioles filed for arbitration. It's actually just a formality since they have until Friday before they have to exchange arbitration figures and there are a few weeks before hearings. The seven unsigned players are Chris Davis, Jason Hammel, Jim Johnson, Brian Matusz, Darren O'Day, Troy Patton and Matt Wieters. Those seven are among 133 who filed, and perhaps the most critical is Wieters. It's never easy going to arbitration with Wieters' agent, Scott Boras, and Dan Duquette would love to avoid it. MLBTradeRumors.com projects that Wieters could earn $4.6 million in arbitration. As critical as Wieters is to the Orioles, it's bad business to get into a nasty hearing with him, though he's universally admired within the organization. The time is coming for a contract extension, and talks are likely to be lengthy and complex. As important as Adam Jones is to the Orioles, Wieters is even more important. His workload, his positive attitude and his ability at a vital position make him a must-sign. The Orioles could try to sign him for a year or two now and put off the inevitable for a year or two.
