OAKLAND, Calif. (AP) - Landon Powell hit his first career grand slam to help the Oakland Athletics beat the Kansas City Royals 10-4 on Wednesday.
Ryan Sweeney had two hits and drove in two runs, while Trevor Cahill won back-to-back starts for the first time in more than two months.
Powell homered off Royals reliever Yasuhiko Yabuta as part of Oakland's five-run second inning after Kansas City starter Brian Bannister left the game with shoulder fatigue.
Mike Jacobs homered for the Royals, who lost two of three against Oakland without manager Trey Hillman. Hillman left the team on Monday to be with his family following the death of his father-in-law.
