One of the best parts about the final day of the MLB regular season is that all 30 teams are in action at the same time. While it's suboptimal for those trying to watch multiple games at once, it makes for an electric afternoon of baseball, after which all of the upcoming postseason matchups are officially finalized.
Entering play on Sunday afternoon, 11 of the 12 playoff participants were set. Seeding in the American League had yet to be decided, but other than the final Wild Card spot in the National League, each of the teams headed to this year's playoffs knew they would be doing so before play began on the final day of the regular season.
