Walters was optioned to Triple-A Oklahoma City on Thursday, Bill Plunkett of the Orange Country Register reports.
Walters appeared in three games for the Dodgers (one start) since his recent call-up, but failed to reach base in each of those opportunities. Thursday's lineup proved to be a bit of an ominous sign, as Yasiel Puig will get the day off, but it will be Andrew Toles, not Walters, who gets the start in right field. Rather than carry an extraneous outfielder, the team will call up lefty pitcher Grant Dayton.
