Davis again did damage to start an inning, taking Indians starter Carlos Carrasco deep to left-center for his third homer of the season in the fifth. Yonder Alonso added a solo shot, his 21st of the season, later in the inning.
It was more than enough support for Gray, who gave up just two hits and walked one in six scoreless innings. He struck out five and induced seven groundouts in a 100-pitch outing.
Carrasco went 6 1/3 innings, allowing five runs on six hits and two walks while striking out 10, his third double-digit strikeout night of 2017.
