There is a dangerous desire in sports to extrapolate recent trends ("momentum") indefinitely into the future. Twins are currently struggling and the Tigers are as hot as the sun, but that means little to nothing about what will happen next.
My rule of thumb for comebacks is that going from long odds to a tie means you've made it halfway there.
The Twins still are statistically 1 game up due to tiebreaks, so the odds are still 60/40 in their favor. If the Tigers get it to 50/50, then they have successfully gotten "halfway" from <1% to 100%.
The fun part about the final week of the MLB season, however, is that you can easily gain 20% in a day with the right set of results.
