Bickford was optioned to Triple-A Oklahoma City on Friday, Bill Plunkett of The Orange County Register reports.
The right-hander has a 3.45 ERA, 1.15 WHIP and 13:3 K:BB over 15.2 innings for the Dodgers this season, but he'll head to Triple-A with Friday's starter, Ryan Pepiot, being promoted to the big-league club. Bickford also pitched well for Los Angeles last year with a 2.81 ERA, so it's only a matter of time before he's back in the majors.
