Zach Links of MLBTR reports that the Phillies claimed Rockies southpaw Ken Roberts off waivers. In the same report, Roberts was optioned to Triple-A Lehigh Valley.
Roberts has not had the greatest season for Triple-A Albuquerque which is known as a hitters atmosphere with a 5.12 ERA but has a 28-4 K/BB ratio. His FIP was also 3.43 which suggests bad luck for Roberts.
Despite the struggles, Roberts had a brief stint in the majors for the Rockies where over nine games he struck out five and walked two with a 5.79 ERA. Again the FIP was much lower at 3.01 for another organization not known to be the best environment for pitchers.
We'll see if he gets a look in September in the majors for it seems like Roberts is much better than his ERA would suggest.
