The Giants optioned McCray to Triple-A Sacramento on Thursday, Evan Webeck of the California Post reports.
McCray appeared in just 22 games for the Giants last season, during which he went 2-for-22 (.091) with two RBI and three runs scored. He improved his performance at the plate in the Cactus League, logging a .792 OPS over 40 plate appearances, but he projects to spend most of his time in the minors this year working as organizational depth.
