The only thing guaranteed at this point is that Cleveland's last game won't be tomorrow. If it ends up being a three-team tie, Cleveland has the best record head-to-head among the three (7-5) while Tampa is 7-6 and Texas is 5-8, so they would get to choose their designation first (A, B, or C).
In that scenario, B plays at A on Monday. The winner gets one Wild Card spot; the loser goes to C on Tuesday and the winner of that game gets the other spot. It appears that Tampa would go to Cleveland on Monday, with the loser going to Texas on Tuesday, and that's before the wild card game would be played on Wednesday, where either Cleveland would be at Tampa, Tampa would be at Texas, or Texas would be at Cleveland.
The winner, regardless of who it is, would head to Boston, while Detroit starts their playoff series in Oakland. Prior to 2012, the wild card winner played the highest seed unless they were in the same division.
I want my $2.
Obligatory 2016 attendance record: 0-1 (10-8 loss to Toronto on 6/25)
If you don't know where you're going, any road will take you there.
