Dodgers' left-hander Julio Urias was optioned to Triple-A Oklahoma City on Sunday, per a team announcement. The move follows a rough stretch for the 20-year-old southpaw, who shoulders a 5.40 ERA after giving up 13 combined runs across his last two starts with the Dodgers. A corresponding move was made to recall right-handed reliever Josh Ravin from Triple-A, who should give the club some bullpen depth in Urias' absence.
