The A’s outrighted Corey Brown to Triple-A Sacramento on Friday, but the outfielder elected free agency instead.
Brown had been designated for assignment Jan. 22 to clear a 40-man spot for Eric O’Flaherty. He first needed to clear waivers before the A’s could even try to send him to the minors. Because he had been designated before, Brown had the right to refuse this assignment.
Oakland had reacquired the 28-year-old from Washington for cash considerations on Dec. 19. He was originally drafted by the A’s as a sandwich pick between the first and second rounds in 2007, but he was traded to the Nationals as part of a deal that sent Josh Willingham to the A’s before the 2011 season.
Brown is a .175 hitter in 36 career major league games, all with the Nationals.
