Marcus Semien hit a grand slam in the eighth inning after his tying homer leading off the fifth, Chris Herrmann had a career-high four hits, and the A’s beat Minnesota 7-2 on Thursday for a winning series in a matchup of contenders.

Semien sent the first pitch from Mike Morin over the wall in left-center for his 13th homer of the year and fourth career grand slam. He matched his career high with five RBIs, also done last year, while notching his fifth two-homer game and second this season.

Ehire Adrianza’s single with two outs in the top of the fifth had put Minnesota ahead after he reached on a bases-loaded catcher’s interference in the first to give the Twins a 1-0 lead.

Jose Berrios (8-5) allowed three runs and six hits in five innings with two strikeouts and three walks to lose his second straight start and third consecutive decision.

The Twins endured their first losing road trip of 2019 at 2-4.
