Dodgers' Ryan Loutos: Dropped from 40-man
Rotowire
The Dodgers designated Loutos for assignment Friday, Kirsten Watson of Spectrum SportsNet LA reports.
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. 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.
