EDGE Analysis

Loutos has given up five earned runs in three major-league innings this season, and he'll now end up as the roster casualty necessary to make room for Chris Stratton on the active roster. Despite his big-league struggles, Loutos owns a 2.41 ERA across 18.2 total innings in Triple-A, so there could be a few other clubs out there willing to add the 26-year-old to their 40-man.
