The White Sox have outrighted right-hander Javy Guerra off their 40-man roster and assigned the reliever to Triple-A Charlotte, Colleen Kane of the Chicago Tribune reports (Twitter link). The Sox claimed Guerra off waivers from the Dodgers on Wednesday.
Guerra posted a 2.45 ERA in 91 2/3 relief innings with Los Angeles in 2011-12, though his peripherals suggested that he may have been a little fortunate to post such a low number. He struggled in 2013, managing only a 6.75 ERA over 10 2/3 IP and spending much of his season in the minors.
