I don't see how the record of a team for their whole season and their September results, correlates to head to head results between two teams in recent play. In my mind, they aren't the same thing. The results are simple. The O's got the better of them earlier in the season. This month, Toronto took 5 of 7. Those results are more telling of who these teams are today, than June results or August results, unfortunately, since the O's bested them in August.
Not exactly the same thing being tested, I agree. But they are very similar things and the results point to momentum (i.e. recent results) not being as influential as overall results (i.e. overall results).
But, they are different. So then do you wanna give me those 5-to-2 odds on each game coming up in October? Not money, but pitchers for the table at the next BSL happy hour? I'll do that for each game. Or the roughly 40-to-1 that parlays to for the sweep.
I think the odds are much closer to the 50/50 outcome of the total season series (or the 560/523 ratio the teams overall records would imply).
Either way the odds of a sweep are low. 12.5% if the games are coin flips. ~2.3% if each game is 5/7 in favor of Toronto.
