The A’s announced the trade Thursday and said Blanks would join the team today in Cleveland as Oakland kicks off a three-city, nine-game road trip. He played parts of six seasons for San Diego, batting .200 in five games this year.
The 6-foot-6 Blanks will likely platoon with Brandon Moss at first base.
To clear roster space, Oakland designated longest-tenured player Daric Barton for assignment. The first baseman was hitting .158 with five RBIs and 14 strikeouts.
If Barton clears waivers and stays with the organization, he could join Triple-A Sacramento for his eighth different season. Barton was once a highly touted prospect, but has never been able to figure it out at the big-league level. He is a .247 career hitter in 551 games.
