BALTIMORE, AUG. 30 -- It was a typical day for the Baltimore Orioles. Someone else got hurt. But the night bloomed into a rare combination of timely hits and overpowering pitching, and the Orioles ended a five-game losing streak with a 6-1 victory over the New York Yankees before 25,796 at Memorial Stadium.

Pete Harnisch threw a five-hitter, going the distance for his 10th victory of the season. Mike Devereaux hit his seventh homer and Cal Ripken drove in two runs as Baltimore (60-69) averted a four-game New York sweep.

With first baseman David Segui now out indefinitely with a knee injury, Mickey Tettleton got his first career start at first base, and helped the cause by snagging a hard-hit ball by Mel Hall in the first inning with two on and two out. Had it gotten through, the Yankees might have led by 2-0.

But from there Harnisch (10-9) settled down. After Oscar Azocar's single in the third, Harnisch retired 12 straight and 17 of the next 18, before Matt Nokes singled to lead off the ninth. Hall doubled Nokes to third and Jesse Barfield's groundout produced New York's only run.

"I had a good fastball," Harnisch said of his 143-pitch effort. "I didn't have much of a breaking ball but I had a pretty good change-up to the left-handed hitters. I was just trying to keep the ball as far down as I could."

"Pete was in complete control," Orioles Manager Frank Robinson said. "We got some runs for him and he kept people off the bases. It was a much more relaxed-type game. We usually make them close before they're over. Tonight he had his good stuff."

Offensive support was there too; the 10 hits gave the Orioles their fourth game with double-figure hits in 26 this month.

Baltimore pitchers had allowed homers in eight straight games, and had been outhomered, 31-10, in the previous 22 games. But Harnisch allowed few hard-hit balls. After the first-inning jam, he allowed just three base runners until the ninth.

After walking eight Aug. 20 in Boston, it appeared as if Harnisch was having trouble with his control. He returned to form tonight, walking two.

"That's the way I've been pitching most of the season," he said. "I had a stretch there where I gave up a lot of walks, but for three and a half months, I was pitching well, so this shouldn't have been much of a surprise."

The Orioles put him ahead with single runs in the first and second innings off Dave LaPoint (6-10). Tettleton's first-inning fly drove in Dave Gallagher, ending the team's zero-for-28 slump with men in scoring position.

Consecutive singles in the second by Craig Worthington, Bill Ripken and Gallagher (two hits on the night) scored the second run. Gallagher was one for 14 in his previous six games.

Devereaux led off the fourth with a homer to left-center on a 1-0 fastball. Worthington (three hits, his first multi-hit game since July 17) then singled to left.

Bill Ripken squared to bunt, and dropped the sacrifice in front of LaPoint, who had plenty of time, but drew first baseman Kevin Maas off the bag with a wild throw. With men at first and second, Gallagher bunted. LaPoint again had plenty of time, and he again drew Maas off the bag.

"I've never made two throwing errors in my life," LaPoint said.

Joe Orsulak popped to second, but Cal Ripken lined a 3-2 pitch over third baseman Randy Velarde to drive in two and finish off LaPoint. It was Ripken's 29th and 30th RBI in his last 36 games; he's four for his last seven with the bases loaded after starting the year one for 16.

"I want to see us out there having a chance to win a ballgame each day," Robinson said. "We haven't had too many chances to win recently. We want to come in here and be able to say, 'Hey, they beat us.'"

The production was more than enough for Harnisch, who hadn't won in six decisions after starting off 9-5. His ERA during the bleak streak was 5.59, with 28 walks. He lasted only 3 1/3 innings Sunday in an 11-5 loss to Cleveland.

"I know when I pitched against Seattle and Boston, I walked a whole bunch of guys," Harnisch said. "But they didn't score. I kept us in the game. . . . In those games, I was really aggressive. The last game, I don't think I was as aggressive. I was stealing for the strike zone, and I paid for it.

"I talked to {pitching coach Al Jackson} too about putting a couple of guys on. It's going to happen to me because I'm basically a high fastball pitcher, and a lot of times I miss high. Guys who are patient don't swing at that pitch."

The Yankees were not patient, especially early.

"This guy beat the hell out of us the last time too {a four-hitter over eight innings June 9}," New York Manager Stump Merrill said. "I thought this might be our toughest game. He threw good and couldn't get his change-up and curveball over and still beat us."

Tettleton set a dubious record in the seventh with his 136th strikeout on the year, setting a major league record for whiffs by a switch-hitter.
