Khris Davis smacked a three-run home run off David Price in the eighth inning to give the A's a 4-1 victory over the Red Sox in Oakland on Sunday.

Davis also drove in Oakland's first run with an RBI single in the first inning.

Daniel Mengden pitched 6.1 innings for the A's, allowing one run on six hits. Blake Treinen got the win, pitching 1.2 scoreless innings and striking out three.

Price pitched 7.2 innings, allowing four runs on nine hits while striking out six.
