If we are going with 92-70 as the benchmark, the teams have to have the following records and win percentages:
Jays 19-8 .704
Red Sox 13-10 .565
Yankees 14-12 .538
A's 18-7 .720
Mariners 17-8 .680
Now what the original analysis doesn't consider is that these teams face each other quite a few times. For instance, the Athletics and Mariners face each other seven times. Given that they both have to win two-thirds of their games, this is going to be deadly for one or both teams. Either one completely dominates the match up and basically eliminates the other from contention, or they both hurt each other's chances. A 5-2 record merely puts one team in line with the win percentage they need. But a 2-5 record eats up nearly all of the loss allocation. The Jays won't have to worry about both of these teams. They'll only have to worry about one, or none.
These are the games left between these teams:
A's/M's - 7 games
BOS/NYY - 3 games
Bos/M's - 3 games
If you assume every team splits those games:
Red Sox 3-3
Yankees 1.5-1.5
A's 3.5-3.5
Mariners 5-5
Subtract that out from the records needed to get to 92 wins and you get these records in the remaining games:
Red Sox 10-7 .588
Yankees 12.5-10.5 .543
A's 14.5-3.5 .806
Mariners 12-3 .800
In this context it looks way better for the Jays. Only the Yankees and Red Sox are the ones to worry about. Someone in Boston could be doing the same calculation for the Jays/Yankees games and really be salivating. But from our perspective, the Jays need to dominate those games so that analysis would be irrelevant.
