John Lowenstein hit his eighth homer for one run and singled in another tonight as the Baltimore Orioles beat the Toronto Blue Jays, 3-0.

Mike Flanagan (2-4) allowed five hits, struck out two and walked none through seven innings. He raised his career record against the Blue Jays to 13-4 as the Orioles won three straight for the first time this season.

Flanagan gave up just one extra-base hit, a double by Garth Iorg in the sixth, and did not walk a batter. Relief pitcher Tim Stoddard gave up two hits before being replaced by Tippy Martinez with one out in the ninth. Martinez completed the game and got his third save.

Flanagan was knocked flat when a hard line shot from the bat of Barry Bonnell struck him on the left bicep in the third inning.

After the game, Flanagan's teammates, coaches and Manager Earl Weaver stopped by his locker to take a look at the prized left arm, which was starting to turn a dark shade of purple.

"I was scared when I saw it," Weaver said of Bonnell's smash. "I just ran out there as quick as I could. I didn't know if we got the guy out or even if we had made a play. The coaches didn't know if there was an out, and I bet half the players on the bench didn't know there was an out. We were just concerned with where the ball hit Mike."

Flanagan told Weaver between innings that his arm was all right, but after the seventh informed his manager it was starting to stiffen. Stoddard came on in relief.

Cheered by the win, Flanagan could laugh at the play. "I was just about ready to put up a pitching screen, especially when (Wayne) Nordhagen hit the first ball through the box the next inning," he said.

With Baltimore leading, 1-0, in the third, Lowenstein homered on a 3-2 pitch from Jim Gott (0-1), the ball going just inside the right field foul pole.

Baltimore scored again in the fifth. Dan Ford walked, went to second on Ken Singleton's infield single and continued to third on shortstop Alfredo Griffin's throwing error. Lowenstein singled to center to drive in Ford.

With two out in the second, Lenn Sakata had been walked by Gott. He raced to second on Al Bumbry's single to left and came in on Rich Dauer's single to right. The Orioles had loaded the bases without scoring in the first inning.
