The White Sox announced that they claimed right-hander Philip Humber off of waivers from the A's (Twitter link). The A's claimed Humber from the Royals last month, only to designate him for assignment to create roster space for Guillermo Moscoso.
Humber posted a 4.15 ERA in 21 2/3 big league innings this year. As short as that stint was, it was the most the 28-year-old has ever pitched in the big leagues. The former first rounder was once considered a top prospect and the Mets sent him to Minnesota in the Johan Santana deal. In 664 1/3 minor league innings, he has a 4.48 ERA with 7.3 K/9 and 2.7 BB/9.
