Jamie Moyer pitches the same way at new Safeco Field that he did in the Kingdome. He's just more effective.
"I probably would have given up four home runs if we were across the street," said Moyer, who hasn't given up a home run in winning both his starts at the Mariners' new home.
Cal Ripken failed to hit his 400th career homer in his fifth straight game, but Griffey got his 384th off Sidney Ponson (9-7) in the first inning, an opposite-field shot to left field.
Moyer (10-5) gave up two runs in the second inning, but that was it. He allowed seven hits and no walks, while striking out one in eight innings. He won his second straight start since missing a start with shoulder stiffness and for the ninth time in his last 10 decisions.
In eight starts in the Kingdome this year, Moyer was 4-3 and allowed nine homers.
The Mariners played their last game in the Kingdome June 27 and moved into Safeco July 15.
"I don't try to pitch any differently here," Moyer said. "I can't afford to do that. I don't want to say I don't have the ability, but I don't have the stuff to do that. I don't have the stuff to start pitching up in the strike zone."
Jose Mesa pitched the nintfor his 21st save in 24 chances.
John Mabry also homered for the Mariners, who lead the majors with 174.
The Mariners, beating Baltimore for the fourth time in five games this season, snapped a tie at 2 with two runs in the sixth. Edgar Martinez and Tom Lampkin each doubled to make it 3-2. One out later, Russ Davis hit an RBI single.
Seattle got its fifth run in the seventh in an unusual way. Brian Hunter walked and went to second on David Bell's groundout. Running with the pitch, Hunter scored from second on Griffey's grounder to first that didn't draw a throw to the plate. Griffey got his 93rd RBI of the season on the play.
"I don't think they're used to somebody scoring from second base on that type of play," Hunter said. "If he (Griffey) gets 100 RBIs, he owes me one."
Orioles reliever Doug Johns was on the mound on the play that Hunter scored and drew manager Ray Miller's wrath for not holding Hunter on base. Miller yanked Johns after the play.
"The pitcher didn't do a very good job of holding a guy (Hunter) who can fly after going 0-2 on him and walking him," Miller said. "He had a huge lead and was flying. When (first baseman Will) Clark got the ball, he looked up and thought he didn't have a shot (at the plate)."
The Mariners tied the score in the bottom of the inning on Mabry's ninth homer.
Ponson gave up four runs and nine hits and three walks in six innings.
"The last couple of games I haven't thrown the ball real good," he said. "I've been giving up the long ball."
