Jim Clancy pitched a six-hitter over eight innings and Toronto had a six-run third inning to win at home.
Clancy (4-4) allowed two hits in the first five innings before the Brewers ended the shutout in the sixth on Earnie Riles' RBI bloop single.
With Toronto leading by 1-0 in the third, Jesse Barfield tripled and scored on Tony Fernandez's single to right. Fernandez moved to second on Damaso Garcia's infield single and scored on Rance Mulliniks' groundout. Lloyd Moseby scored Garcia with a double to knock out loser Ray Burris (4-6).
First baseman Cecil Cooper's fielding error on Willie Upshaw's line drive off reliever Jaime Cocanower allowed Moseby to score and George Bell drew a walk. Moseby advanced to third on a flyout and scored on a wild pitch. One out later, Cocanower walked Len Matuszek and Barfield to load the bases, then walked Fernandez to score Bell for a 7-0 Blue Jays lead.
Milwaukee has lost nine of 12 games and fallen 11 games behind the first-place Blue Jays. "You're talking about Toronto, Boston, Detroit, Baltimore and New York. They might be five of the best teams in baseball," Milwaukee Manager George Bamberger said. "Let's face it, I don't think we're going to beat out those five teams."
