TORONTO, AUG. 26 -- Three days ago the Toronto Blue Jays were the highest-scoring team in baseball. Today the Boston Red Sox shut them out for the third straight time.

Jody Reed's two-out single in the eighth inning scored Tom Brunansky from second base as the Red Sox made it two 1-0 triumphs in a row and extended their American League East lead to four games over Toronto.

The Blue Jays, who have lost six of their last seven, managed only two hits off starter Greg Harris (11-5) and Jeff Gray, who got the last four outs. One was a second-inning single by Fred McGriff that struck the right field wall about a foot short of home-run distance. The other was an eighth-inning leadoff infield single by Greg Myers.

All season the Blue Jays have been betrayed by the inability to execute simple plays. Today, in addition to Junior Felix's failure to lay down a bunt after Myers's hit, Toronto was unable to execute a simple pitchout in the eighth -- and paid dearly.

Todd Stottlemyre, the Blue Jays' starter, took a three-hit shutout into the inning. He walked leadoff man Brunansky on four pitches, then struck out Tony Pena. On a 1-2 pitchout to Luis Rivera, Stottlemyre threw one that drifted off catcher Myers's glove, enabling Brunansky to take second. After Rivera fanned, Reed lined his game-winning single to left on a 1-2 pitch, with Brunansky just beating the throw from Glenallen Hill.

"We won the game because Brunansky had a whopping lead off second base," said Boston Manager Joe Morgan. "Nobody else on our team would have scored except {Ellis} Burks."

"The guy {Hill} has a pretty good arm and you have to get a good jump," Brunansky said. "He made a good throw, but it bounced just high enough so I could slide under the tag."

Of the pitch to Reed, Stottlemyre said: "It was a breaking ball and he seemed to keep his hands back good. He's a tough out. He's not hitting .300 for nothing."

But if Stottlemyre (11-14) found no fault with that delivery, he blamed himself for the wild pitch that set it up. In a recent start he had thrown a strike on what was supposed to be a pitchout. This time he overcompensated.

"That was the difference in the ballgame," Stottlemyre said. "I want to do two things -- make sure I unload the ball and make sure I get it out. I guess I brought my arm across my body too much. It got out too far, it kept cutting and it got away from him {Myers}. Two mistakes -- a leadoff walk in the eighth and throwing the ball away on a pitchout. That was enough."

When your team doesn't score, one mistake is enough, as David Wells learned Saturday when Dwight Evans's homer beat him, 1-0. On Friday Jimmy Key pitched seven scoreless innings, but the Red Sox beat reliever Duane Ward with two runs in the ninth.

"Our pitching was the best we've had all year," said Toronto Manager Cito Gaston. "Neither team wore the ball out, that's for sure. We had a chance to score today, but the ball hits the mound into a double play. Then they score on a pitchout. It was a tough weekend."

The mound shot to which Gaston referred came in the seventh inning. Harris hit Tony Fernandez with a pitch and issued a one-out walk to McGriff. John Olerud then lined a shot back at Harris, but the ball ricocheted off the mound to second baseman Reed, who turned it into a double play.

"That was a base hit for sure," said Morgan. "You have to be lucky to win games like this. We need all the edge we can get."

Harris, whose 11th victory marked a high for his 14-year pro career, struck out eight to come within one of his personal best, recorded with Cincinnati in 1982. He said he was inspired by the efforts of Dana Kiecker and Roger Clemens in the previous games.

"Those were two great games and they gave me a little extra feeling," Harris said. "You want to try to match something like that. You don't want to be the failure."

The Red Sox last recorded three straight shutouts in August 1962 -- by Gene Conley, Bill Monbouquette and Ike Delock. The Blue Jays were blanked three in a row once before, in May 1981.

The Blue Jays, who won Thursday's game by 4-3, were zero for 27 with men in scoring position during the three losses. The 3, 4 and 5 men in the batting order were two for 42. Toronto, which led the majors in homers as recently as Saturday, has not hit one in nine games. Conversely, the Red Sox have not allowed one in 10 games, their longest stretch since 1975.

"This is good for the team, doing things that haven't been done in baseball for a while," Harris said. "Hopefully, this will be one of those great series wins that helps us pull away."

Toronto played without cleanup batter George Bell, bothered by a buildup of fluid in his right eye. Bell, who took himself out of Saturday's game, was fitted for glasses and came to the park, but his availability will be on a day-to-day basis. Fernandez left in the seventh after he was struck in the left knee by a pitch; he will await X-rays to see if it is anything more than a bruise.
