The Baltimore Orioles vacated the rarefied air of first place tonight and descended to low comedy when the Cleveland Indians got eight runs on eight hits in the eighth inning and went on to score a 10-4 victory.

The Orioles were leading, 3-1, and Scott McGregor was pitching a one-hitter before 31,288 at Memorial Stadium when things came unglued. When the inning was over, 13 Indians had come to the plate.

The last three runs in the Cleveland eighth came on three straight infield singles off reliever Tippy Martinez, called in to stem the barrage when Don Aase was unable to do the job.

Martinez got George Vukovich, the first batter he faced, to ground to the hole between second and first base. Second baseman Rich Dauer made a diving grab, but the potential inning-ender went awry when Dauer threw the ball past first base for a single and error. Succeeding run-scoring infield singles left the Orioles hopelessly out of the running at 9-3.

Each team scored a run in the ninth. The Indians' Tom Waddell ended the game by striking out Fritz Connally on a 3-2 count with the bases loaded.

Baltimore had entered the game tied with Detroit for first place in the American League East at 10-6. McGregor (1-2) was the loser. Don Schulze (2-0) was the winner, with relief help from Dave Von Ohlen and Waddell.

For a change, the Orioles' management had no giveaway promotion tonight to lure customers, but the teams staged giveaways of their own to record the first runs of the game.

Wayne Gross of the Orioles booted leadoff batter Brett Butler's one-hopper down the third base line to open the action, and Butler stole second base on McGregor's next pitch. He advanced to third on a grounder and scored on a sacrifice fly, giving the Indians a 1-0 lead.

Cleveland gave the unearned run back in the second. Eddie Murray led off with a single, took second on catcher Butch Benton's passed ball, advanced on a grounder and scored on Larry Sheets' infield single.

Meantime, McGregor, who had looked awful in his previous start, lasting only 1 1/3 innings and yielding seven hits and five runs to Texas, began mystifying the Indians with an assortment of offspeed pitches and sweeping curves. He retired nine straight after the game-opening error, then walked Julio Franco to start the fourth inning.

McGregor complained of blurred vision after the Texas start and was sent back to Baltimore for physical exams, but nothing turned up. Doctors told him to lay off coffee, and evidently it worked.

The Orioles took a 2-1 lead in the fourth. Cal Ripken led off with a double down the left field line, advanced to third on Murray's ground-out and scored on Fred Lynn's long sacrifice fly to the top of the center field wall, which Butler caught with a leaping grab.

They continued to chip away at starter Don Schulze in the fifth inning. The Orioles got up a run on a walk, a sacrifice bunt and Jim Dwyer's two-out, full-count ground single up the middle, which just eluded second baseman Tony Bernazard's diving effort.

It wasn't until two were out in the Indians' sixth that McGregor gave up a hit. After Bernazard and Butler each hit the ball hard, but near defenders, Franco, the league's leading hitter at .434 entering the game, drove McGregor's first offering into left for a single.

The big crowd applauded McGregor's 5 2/3-inning no-hit effort. He responded by retiring Joe Carter on a routine fly ball.

But McGregor's touch deserted him in the eighth inning. He walked leadoff man Carmen Castillo and gave up back-to-back doubles by Benton and Bernazard that tied the score at 3.

Manager Joe Altobelli let his starter face one more batter, but after Butler advanced Bernazard to third with a sacrifice he called for Aase, who was making his first appearance in a week. It was not Aase's night.
