Baltimore players could sense there was something different about Nolan Ryan Tuesday night.

They were right. The visiting Orioles rocked the California Angels' pitching star for 12 hits and seven runs in 5 1/3 innings enroute to their seventh straight victory, 8-6.

California's ninth loss in 10 games dropped the Angels into fourth place in the American League West.

"Everbody in the dugout was commenting in the first inning that Ryan wasn't throwing as hards as he had in the past," said rookie Larry Harlow after spearheading the Oriole attack with three hits off Ryan, stealing three bases and scoring two runs.

Harlow, who was hitless in 12 atbats going the game, struck out three times and hit a sacrifice fly in his only game against Ryan last season.

"After seeing him throw tonight, we knew we could be more aggressive," Harlow said. "At the beginning of a game, you feel intimidated by him. When you face Ryan you think fireball . . . heater . . . strikeouts."

Ryan can't explain his sudden ineffectiveness. He has allowed 16 earned runs in his last 16 1/3 innings of work and his earned-run average has soared to 4.14.

"I can't put my finger on it," Ryan confessed. "It's not one thing. Once you get into bad habits, one thing leads to another. I don't know what I can do.

The only thing you can do is keep studying films."

Baltimore Manager Earl Weaver knows how Ryan feels.

"Baseball is a funny game," said Weaver. "You're on top of the world one week and wondering what happened the next. The other teams in the East will be thinking now, 'Oh, god, the Orioles are coming back again.'" Mariners 4, Yankees 3
