Athletics pitcher Sonny Gray was stuck with his first loss Wednesday despite allowing just one earned run on three hits in seven innings while striking out nine and walking none in his team's 2-0 defeat against the Red Sox.

Gray (4-1) gave up a leadoff single in the second inning and watched the runner advance to second on a wild pitch with one out before scoring on a two-out single. He allowed another single in the third and was perfect over the remainder of his outing, but the damage was done.

Gray owns a 1.61 ERA and 53:15 K:BB ratio in 56 innings. He'll square off with the Astros in Houston Tuesday.
