Dave Stieb won for the first time in 11 starts this year with a four-hitter that enabled the Toronto Blue Jays to beat the Chicago White Sox, 6-0, last night in Toronto.

He had home run help from Rick Leach and Rance Mulliniks.

Stieb, the AL's ERA leader last year, had not won a regular-season game since last Sept. 27 and was 0-6 before last night's game. His ERA had been 6.83.

"I feel the monkey's off my back," he said. His locker contained many gifts from superstitious fans, including a Buddha that now claims a 35-0 record at breaking losing streaks.

*A's 6, Yankees 3: In Oakland, Jose Canseco's 15th homer this season gave left-hander Curt Young (3-1) an early lead and helped end the A's five-game losing streak.

Young left the game in the seventh inning after he broke Mike Pagliarulo's nose with a pitch. Pagliarulo's wrist was hurt, too and he was taken to a hospital.

*Twins 13, Red Sox 5: In Minneapolis, Roy Smalley drove in four runs with two homers, including one in a five-run third inning that lifted Minnesota to victory.

Smalley's homers, one right-handed and the other left-handed, helped Keith Atherton (2-2) win his first game since Minnesota acquired him May 20. He worked 5 1/3 innings of four-hit relief.

*Brewers 11, Indians 7: Milwaukee's Cecil Cooper went three for six and drove in five runs in Cleveland. The Indians had 15 hits and left 15 men on base.

Cooper doubled home two runs in the third inning, another with a single in the fifth and two more with a single in the sixth.

*Royals 12, Rangers 2: Rudy Law had three doubles and scored four runs and Steve Balboni and Willie Wilson each homered in Kansas City, Mo.

Dennis Leonard (5-4) gave up six hits through seven innings, struck out four and walked one before giving way to Scott Bankhead. The loss went to Bobby Witt (2-4).

Texas outfielders Pete Incaviglia (twisted knuckle) and Gary Ward (elbow hit by pitch) left the game with minor injuries.

*Mariners 8, Tigers 7: Bob Kearney's one-out double in the 12th ended the game in Seattle.

Jim Presley led off the inning with a double off Chuck Cary (0-1). After Domingo Ramos popped up trying to sacrifice, Kearney doubled over left fielder Dave Collins' head.

Mark Huisman (1-2) held Detroit hitless the last three innings.
