CHICAGO (AP) The Cubs have claimed reliever Ryan Cook off waivers from the Boston Red Sox.
The 28-year-old right-hander is 13-12 with 17 saves and a 3.43 ERA in 217 relief appearances for Arizona (2011), Oakland (2012-15) and Boston (2015).
Cook had a 18.69 ERA in nine appearances for Oakland and Boston last year. He split most of the season between Triple-A affiliates after being slowed by injuries in 2014.
