Although the Yankees are still mathematically alive in the AL East race, odds are they will go to the postseason as a wildcard team, and odds are they will host the Twins at Yankee Stadium. The Yankees have already punched their postseason ticket. Once the Red Sox clinch the AL East and the Twins clinch the second wildcard spot, everything will be set.
The Wild Card Game is, technically, its own postseason round. Teams set their 25-man Wild Card Game roster, then can make adjustments prior to the LDS. That leads to some unique roster construction.
