David Pinto has contacted MLB to determine what would happen in the event of a 3 way tie where a division winner and wild card would make up 2 of the 3 teams. The answer is a multi-game playoff.
there would be a two game playoff for the division, and the two losing teams would then play another game for the wild card. However, it is being discussed that if the two game playoff results in a 1-0, 1-1, 0-1 result, that the third playoff game would be abandoned, the 1-0 team would be the division winner and the 1-1 team would get the wild card.
Meanwhile Kurt is tracking the various clinching scenarios in his sidebar.
