WEST SACRAMENTO, Calif. (AP) — Luis Morales pitched seven sparkling innings, Zack Gelof homered, doubled and drove in four runs, and the Athletics beat the Detroit Tigers 7-0 on Wednesday night to sweep their three-game series.

Making his fourth career start, Morales (2-0) allowed two hits with two walks and seven strikeouts. The 22-year-old rookie from Cuba lowered his ERA to 1.19 in five major league appearances.

The AL Central-leading Tigers lost their fourth in a row and fell a half-game behind AL East-leading Toronto for the best record in the American League.

Brett Harris and Nick Kurtz each had two hits and scored two runs.

Harris doubled off Detroit starter Casey Mize leading off the fourth and scored when a throwing error by Mize allowed Gelof to reach safely, making it 5-0.
