The Orioles signed center fielder Corey Patterson yesterday to a one-year deal, leaving starting pitcher Erik Bedard as the club's only remaining arbitration-eligible player. Patterson will make a base salary of $4.3 million in 2007, the midpoint between the Orioles' offer ($4 million) and the number ($4.6 million) filed by Patterson's agent, Scott Boras. "The process is made to negotiate a deal," Orioles vice president Jim Duquette said. "We've had a willingness and a track record here of winning arbitration cases, but you never want to go. It's only when you feel like the other side is being unreasonable when you want to go. There were a couple of signings within the class that made it apparent that a midpoint settlement would be a proper one."
