Santiago (4-4) allowed six runs on seven hits and four walks while striking out six over six innings, but received no decision Sunday against the Athletics.
Santiago gave up a grand slam and a solo homer in the fourth inning that accounted for five of his six runs, but the Angels' offense came up big after his departure to take him off the hook for a potential loss. He's now failed to post a quality start in six of his last eight starts, and his ERA is at 5.27. He'll make his next start Saturday at Boston.
