OAKLAND (AP) — Bruce Maxwell of the Oakland A’s has become the first major league baseball player to kneel during the national anthem.

Maxwell dropped to a knee just outside Oakland’s dugout on Saturday, adopting a protest started by former San Francisco 49ers quarterback Colin Kaepernick in response to police treatment of blacks. Maxwell’s teammates stood in a line next to him. Teammate Mark Canha, who is white, put his right hand on one of Maxwell’s shoulders.
