Rance Mulliniks and George Bell homered in support of Dave Stieb's four-hitter in Toronto. Stieb (14-5), who struck out 11 in beating the Twins, 2-1, last Sunday, pitched his ninth complete game of the season. He struck out 10.
"Even after 222 innings, I feel stronger now than I ever have in the past," said Stieb, who lowered his league-leading ERA to 2.34 in pitching his 18th career shutout. "Without a doubt, this is the greatest I've ever felt this late in a season."
The Blue Jays chased starter Bobby Castillo (2-1) after 1 2/3 innings with a run in the first and two in the second.
Damaso Garcia started the Toronto first with an infield single, stole second and went to third on catcher Tim Laudner's errant throw. Dave Collins gave the Blue Jays a 1-0 lead with a sacrifice fly.
Bell led off Toronto's second with a single and Mulliniks followed with his third homer of the season, over the right field fence.
Toronto made it 4-0 in the third on Bell's one-out double after Lloyd Moseby had led off with a walk against reliever Pete Filson.
