NEW YORK (AP) -Alex Rodriguez made the New York Yankees forget Kei Igawa's forgettable debut. A-Rod hit a grand slam off Chris Ray with two outs in the ninth inning, giving the Yankees a memorable 10-7 victory over the Baltimore Orioles on Saturday. Rodriguez homered twice, doubled and drove in six runs. Two days earlier, he popped out with the bases loaded to end the eighth in a 7-6 loss to Tampa Bay, a performance reminiscent of his October flop. Igawa left after five mediocre innings trailing 7-3. But Jason Giambi hit a three-run homer in the eighth off Danny Baez to get the Yankees close. Ray (0-1) got the first two outs of the ninth before Robinson Cano singled, Derek Jeter walked and Bobby Abreu was hit by a pitch. Rodriguez then connected on a 1-2 pitch, and knew it was gone as soon as he hit it. The ball landed in the black section of the bleachers in center for his 14th career slam and, after Rodriguez reached the dugout, Jeter shoved him back on the field for a curtain call. Mariano Rivera (1-0) got the win with a one-hit ninth. Melvin Mora tied a career high with five RBIs for Baltimore,
