September 14, 1984 Blue Jays 7, Tigers 2 (93-54)
At this point in the season, the Blue Jays pretty much needed to sweep the Tigers in their final head to head series, and they got off to a good start behind a nice outing by starter Jim Clancy. He held the Tigers to four hits through five innings, and the Jays capitalized on more Jack Morris struggles, as he got hit for five runs in six innings.
Lou Whitaker was the only real offensive star. He went two for four, scored a run, and drove in the other Tiger run.
With the loss, the Tiger’s magic number was stuck at six. So regardless of what happened the rest of the weekend, the Tigers couldn’t finish off the division this week against their arch rivals.
