The Cubs have claimed lefty Edgar Olmos from the Orioles, Roch Kubatko of MASNsports.com tweets. Baltimore exposed Olmos to waivers to clear roster space for the signing of Hyun Soo Kim, and Chicago grabbed him back after originally losing him just weeks ago to the O’s by the same procedure.

Olmos is a 25-year-old southpaw who’s changed hands quite a bit in the last few seasons. He obviously has an intriguing arm, and has shown a mid-90s fastball in his brief time in the majors. At Triple-A in 2015, Olmos worked to a 3.55 ERA with 9.3 K/9 against 3.5 BB/9 at Triple-A last year.
