Bruce Kison, whose career has been slowed by arm surgery performed two years ago, held Baltimore to four hits over seven innings and Bobby Grich and Tim Foli each drove in three runs as the California Angels beat the Orioles, 8-4, today.

Don Baylor also homered for the Angels, who won their 11th in 13 games at home this season.

Kison, who won only one game in 1981, earned his first victory of the season. "There's still room for improvement," he said. "At times, I got into one of those streaks where I couldn't help walking people.

"There was some real good defensive plays behind me, which, as a sinker ball pitcher, I need."

California took a 2-0 lead in the first inning when Juan Beniquez doubled and scored on Baylor's homer off Dennis Martinez (2-3).

The Orioles scored in the second on singles by Eddie Murray, Terry Crowley and John Lowenstein.

Baltimore loaded the bases with none out in the fifth on walks to Rick Dempsey and Bob Bonner and Al Bumbry's bunt single, but Rich Dauer hit into a double play and Ken Singleton grounded out.

The Angels made it 3-1 in the sixth on a walk to Grich and Foli's two-out triple.

They scored five more runs in the seventh, with Grich hitting a three-run homer and Foli driving in two more with a double.
