I'm not sure the Yankees have clinched home-field advantage yet. The Yankees hold the tiebreaker over the Tigers, but the season series between the Twins and the Yankees was tied 3-3. The Yankees are up 2 games, but with 2 games to play the Twins or Tigers could tie them in record. In the event that the Twins and the Yankees finish with the same record, I'm not sure what the tiebreaker is, as the season series was a tie. In the event that the Twins, Yankees and Tigers all finish with the same record, Minnesota would be the Wild Card, as the tie for division leader is broken first (and the Tigers hold that tiebreaker over the Twins). In that case, the Yankees would have home-field advantage. Potential dates for two playoff games in NY: Tue Oct 3 - NLDS 1 / ALDS 1 Wed Oct 3 - NLDS 1/ ALDS 2 Wed Oct 11 - NLCS 1 / ALCS 2 Wed Oct 18 - NLCS 6 / ALCS 7 For these dates, only for the last one would the National League game be definitively forced to happen in the afternoon. For all the others it remains "up in the air."
