Trevor Cahill combined with two relievers on a one-hitter and the last-place Oakland Athletics completed a three-game series sweep, their first in more than three months, with a 4-0 victory Wednesday night. Cahill retired 16 consecutive batters after Nelson Cruz reached on a fielder's choice in the second inning. When the rookie right-hander walked Kinsler with two outs in the seventh, Oakland already led 4-0.

Rajai Davis put the A's ahead to stay when he was hit by a pitch in the first, stole his 38th base and scored on a double by Scott Hairston. Davis, who also scored the first Oakland run and matched a career best with four RBIs in Tuesday's 6-1 victory, added an RBI double in the sixth before scoring on Ryan Sweeney's sacrifice fly.

Landon Powell homered for Oakland, his drive to straightaway center chasing Dustin Nippert (5-3) with two outs in the sixth. Nippert gave up four runs and five hits.
