OAKLAND, Calif. - Alex Rodriguez hit a grand slam and drove in five runs and Randy Johnson dominated for the Yankees.

Johnson, 42, in his second season with New York, allowed one run and five hits in seven innings, throwing 106 pitches. He allowed only three runners past first, one when Mark Kotsay reached second on first baseman Jason Giambi's error in the first.

Meanwhile, Barry Zito was knocked out after 11/3 innings, the shortest outing of his career, allowing seven runs and four hits. He is 0-6 with a 7.94 ERA in his past eight starts against the Yankees.

Rodriguez's 12th grand slam highlighted a seven-run second. Hideki Matsui homered on opening day for the second straight season, a three-run shot in the fourth, and finished with four hits and four RBIs.

NOTEABLE: A's shortstop Bobby Crosby injured his left hand on Robinson Cano's stolen base in the third. Cano's spikes cut and bruised Crosby's index finger. Crosby made an error in the next inning and was replaced by Antonio Perez. Also, Frank Thomas homered leading off the second for Oakland. It was his first game since July after playing only 34 games in 2005 with the White Sox because of separate left ankle fractures.
