The Dodgers optioned Bickford to Triple-A Oklahoma City on Tuesday.
Bickford covered 2.2 innings in total while making relief appearances in three of the past four days, so his demotion is likely the result of the Dodgers wanting to add a fresh arm to the bullpen in advance of Tuesday's game against the Mets. Right-hander Jake Reed was recalled from Triple-A and will replace Bickford in the bullpen.
