MESA, Ariz. -- Coco Crisp belted a grand slam and Eric Sogard hit a go-ahead sacrifice fly Sunday before the A's broke it open in a 15-7 victory over the Cubs in the Cactus League opener for both teams.

Cubs starter Carlos Zambrano faced the minimum over his two innings, striking out the first two batters of the game. He walked Kurt Suzuki to start the second but got Andy LaRoche to hit into a double play.

Matt Garza (0-1), making his first appearance for the Cubs, didn't fare as well. The A's loaded the bases in the third on two hits and a walk against the right-hander. Crisp, who is 1-for-13 against Garza in his regular-season career, tied the game with his first spring homer. Garza faced eight batters that inning.

Matt Carson doubled to lead off the Oakland fourth and scored one out later on Sogard's fly ball to center. The A's took advantage of two errors by Tyler Colvin in right field and added seven more runs in the seventh off Justin Berg to stretch the lead to 13-4.

The Cubs took a 4-0 lead in the first inning against A's starter Trevor Cahill, as Marlon Byrd and Aramis Ramirez each hit RBI singles and Alfonso Soriano added a two-run double. Cahill was relieved after facing seven batters in the first.

The contest was Mike Quade's first Cactus League game as Cubs manager. He took over for Lou Piniella in August and received a two-year contract in November. The weather was very Chicago-like, with a game-time temperature of 49 degrees.

Up next: Randy Wells, in the mix for one of the openings in the rotation, makes his first start Monday at 2:05 p.m. CT as the Cubs play host to the Brewers at HoHoKam Park. Wells is coming off a disappointing 8-14 season. Tyler Colvin, who has been working out at first base, will start in right field and Reed Johnson will lead off and play center. Carlos Pena and Alfonso Soriano will also be in Chicago's lineup.
