A two-run home run by Gary Roenicke in the bottom of the ninth inning gave the Baltimore Orioles a 7-6 victory over the visiting Tigers last night after Detroit had gone ahead in the top of the ninth on Lance Parrish's second homer of the game.

The victory pulled the Orioles into a third-place tie in the American League East with the Tigers, last season's World Series champions.

Roenicke hit his 15th homer off Bill Scherrer (3-2), the fourth Tigers pitcher, after Rick Dempsey had led off with a single and was sacrificed to second.

"When you don't get many hits, you've got to knock people in," said Roenicke, who has a .213 batting average but has driven in 43 runs with 47 hits. His last 22 hits have produced 25 RBIs.

The winner was Don Aase (10-6), who gave up the go-ahead Parrish homer in the top of the inning.

The Orioles lead the major leagues with 212 homers and Parrish's second homer gave him 28 and the Tigers 200. It's the first time in major league history that two clubs in the same league have hit 200 or more home runs in the same season.

The Orioles, held to two hits through six innings, scored four runs in the seventh to tie at 5.

Reliever Chuck Carey walked in two of the runs and a two-run single by Alan Wiggins tied the score.

The Tigers took a 5-1 lead in the first two innings. Parrish hit a two-run homer to cap a three-run first and Kirk Gibson had a two-run single in the second, knocking out starter Mike Flanagan.

Gibson, who drew the first of his three walks before Parrish's homer, also stole two bases to increase his total to 30.

Tigers starter Juan Berenguer allowed only Cal Ripken's 25th homer in the first and a single by Wiggins in the third before the seventh.
