The Cubs have claimed Jason Berken off of waivers from the Orioles, Doug Padilla of ESPNChicago.com reports (on Twitter). Baltimore had designated the right-hander for assignment four days ago in order to free up roster space for Zach Phillips.
Berken spent most of the 2012 season at Triple-A, where he posted a 3.50 ERA with 6.1 K/9 and 2.4 BB/9 in 26 starts. The 28-year-old appeared in just one game with Baltimore this year, but he was a fixture in the Orioles' rotation in 2009 and in their bullpen from 2010-11. The Cubs claimed right-hander Miguel Socolovich off of waivers from Baltimore less than a month ago.
