In the 13 games Baltimore has played since the conclusion of the major league baseball strike, Eddie Murray has hit six home runs and driven in 19 runs; in the last seven games, Murray has knocked in 16 of those 19.

Against the Seattle Mariners Monday night in a game Baltimore won, 12-8, Murray was four for four -- a double, two singles and his 14th homer of the year driving in three runs.

"I'm amazed at those statistics," Murray said. "I didn't know I was hitting that well because I don't follow that stuff. But it feels good. It's been a long time since I hit the ball that well."

Murray wasn't the only Oriole who teed off against Seattle.Rich Dauer, who hit only two homers in 1980, socked a pair of them, a two-run blast in the third and a three-run shot in the fourth, his second and third of the season.

"That's unbelievable," said Dauer. "I never thought I'd hit two home runs in major league game. But in this park (Kingdome) it can be done because of the small dimensions. And I'll tell you what: if Eddie Murray played here he'd hit 60 homers a season."

And how may would Dauer hit?

"Well," he said, smiling, "maybe five if I was lucky."

The Orioles wasted little time shredding Seattle starter and loser Jerry Don Gleaton (4-7), the first of four Mariner pitchers, and sending the Mariners on their way to their fifth straight loss.

After Al Bumbry had walked in the first, Ken Singleton hit his 14th homer of the year for a 2-0 Oriole lead. With one out in the third, Bumbry was safe at second when Seattle's Tom Paciorek missed a line drive in left. Dauer then hit the first of his two home runs for a 4-0 advantage.

With two out in the Oriole fourth, Rick Dempsey singled, extending his hitting streak to seven games, and Bumbry singled. Dauer then ripped a curve ball into the left-field seats for a 7-0 Oriole lead. Baltimore got two more that inning. After Murray doubled, Mariner Manager Rene Latchmann replaced Gleaton with Bob Galasso, Doug DeCinces promptly his a shot to Seattle third baseman Danny Meyer and Meyer threw wildly to first and Singleton and Murray trotted across the plate for a 9-0 lead.

Through three innings, winner Dennis Martinez (9-4) had pitched nearly perfect ball, allowing only a walk to Bruce Bochte in the first. But Martinez faltered im the fourth, giving up successive singles to Bochte, Paciorek and Richie Zisk and then a grand slam to Seattle right-fielder Jeff Burroughs.

Baltimore added two runs in the fifth of a two-run single by Murray and its 12th run in the eight on Murray's homer. The Mariners refused to pack it in, however, scoring three in the seventh and one in the ninth on Zisk's two-out, bases-empty homer to left.
