but it still puts a premium on having that one ace pitcher, and having your rotation lined up just right, rather than on having a great, postseason-worthy season.
I wonder how likely it is that the 5th team would have to win game #162? If they did, then I doubt for example, that the Mariners would be able to throw Felix in a one game playoff.
Unfortunately you can't go back and look at previous years standings to see the difference between 5 & 6 because they weren't playing for anything at the time. I would assume though that just based on the number of teams that would still be alive going into he final weekend that the chances of the #5 team being able to throw their ace in game 163 aren't very high.
