The D-backs claimed right-hander Brad Bergesen off waivers from the Orioles, two days after he was designated for assignment by Baltimore.
Bergesen, who is 17-24 lifetime with a 4.68 ERA, had his contract purchased by the Orioles on July 17 when Miguel Socolovich was optioned to Triple-A. But Bergesen didn't get to pitch before he was DFA-ed a day later.
In 101 innings as both a starter and a reliever for Baltimore last season, Bergesen went 2-7 with a 5.70 ERA. In his last 10 games with Triple-A Norfolk this year, Bergesen posted a 2.35 ERA, prompting his call-up.
But it didn't last long, and now the 26-year-old, who spent the last three seasons with the Orioles, is a D-back. He'll likely pitch in a long relief role.
"I'm really excited. It's kind of that nervous and excited feeling," Bergesen told the Baltimore Sun. "It's my first time in a new organization, it's a fresh start, and I'm looking forward to it. At the same time, Baltimore is a great organization, the only one I've ever known. I've made so many great friends that I'll really miss."
Adding Bergesen fills out Arizona's 40-man roster, and means the club will have to make a corresponding move in order to put him on the 25-man roster.
