PHOENIX (AP) _ Johnny Damon singled, doubled and tripled and Jose Ortiz and Jason Giambi hit back-to-back homers, leading the Oakland Athletics to a 12-1 win Friday over the San Diego Padres.

Terrence Long had four singles and drove in two runs for the A's, who have won 13 of 15 games. Eric Chavez added three hits, including an RBI single in Oakland's five-run first.

Ortiz, who hit .351 in the minors last season and will take over from the departed Randy Velarde at second base for the A's this year, hit his fourth homer of the spring after Damon's leadoff triple in the second.

Giambi, who is trying to wrap up the final details of a six- or seven-year contract with the A's, followed with his fourth homer of the spring. Long added an RBI single later in the inning as the A's took an early 9-1 lead.

Eric Owens had an RBI single in the second for the Padres, who had their six-game winning streak snapped.

San Diego, which entered the game with a .309 team batting average this spring, managed just six hits _ five singles and a double. And the Padres, who had committed only one error in their previous five games, had three in the first inning Friday.

San Diego shortstop Santiago Perez, fighting for a roster spot as a backup infielder, left the game in the first inning with a bruised right shin and foot after Adam Piatt slid in hard while breaking up a double play.

Tim Hudson, making his second-to-last spring start before pitching for the A's on opening day at Seattle, allowed one run on five hits in seven innings.

San Diego starter Woody Williams gave up nine runs _ six earned _ on 12 hits in 3 1-3 innings. He had allowed only three runs in his previous 10 innings this spring.

After the game, the A's optioned outfielder Eric Byrnes to Sacramento of the Pacific Coast League and reassigned catcher Cody McKay and infielder Miguel Cairo to their minor league camp.
