Bergesen will make $800,000 this season after earning $434,000 in 2011. He sought $1.2 million.
The Orioles haven't lost a hearing since 1995 with pitcher Ben McDonald. They're 7-0 with general counsel H. Russell Smouse.
Yesterday's hearing included Smouse, executive vice president Dan Duquette, director of baseball administration Tripp Norton and assistant director of major league operations Ned Rice.
Bergesen, 26, was 2-7 with a 5.70 ERA in 34 games, including 12 starts, last season. He achieved Super Two status, making him arbitration-eligible for the first time.
"It definitely is a process," he said. "This is my first time going through it. We didn't see eye to eye all the way through, but it's over with. The decision's been made and there's no ill will going forward at all. My agent felt like this was something we should do. Now it's over with and I can put all my attention and focus toward having a good year, and that's where I'm at now.
"Once you're in the hearing, you really focus on the positives in your career, and obviously the other side is doing the opposite. There's no way to tell why they chose one way or the other, but like I said, it's nothing that's going to make me destroy myself mentally, thinking why I lost. There's no way of knowing. It's just behind me now. Who knows what the reason was?"
The Orioles have one case remaining, with center fielder Adam Jones' hearing scheduled for Feb. 17.
Jones is seeking $7.4 million and the Orioles countered at $5 million. He made $3.25 million last season.
Note: The Orioles have signed pitcher Stuart Pomeranz to a minor league deal, according to Kevin Goldstein of Baseball Prospectus.
The Cardinals drafted Pomeranz in the second round in 2003, but his career has been derailed by injuries. He's never pitched above Double-A, he missed the 2008 season and he spent 2009 in an independent league. He appeared in two games with Double-A Chattanooga last summer, allowing five runs (four earned) and three hits, and walking three, in 1 1/3 innings. He was 1-6 with a 3.67 ERA in 51 games with Double-A Tulsa in 2010.
Pomeranz is 34-34 with a 4.70 ERA in parts of eight minor league seasons.
