OAKLAND — Marcus Semien homered twice and broke open a close game with an eighth-inning grand slam to give the Athletics a 7-2 Fourth of July win over the Minnesota Twins.
Semien had tied the game with a solo home run in the fifth when he stepped to the plate in the eighth with the bases loaded and the Athletics leading 3-2. He hit the first pitch he saw from reliever Mike Morin for his 13th home run of the season and fourth career grand slam.
Wei-Chung Wang got his first major league win and a depleted bullpen held up its end as the Athletics took two of three from the American League Central leaders before a crowd of 20,836.
