A couple other Big Papi postseason homers, both in the Bronx, that are forgotten by many but were absolutely huge when they were hit:
... Game 7 ALCS '03, top of the 8th, off lefty David Wells, brought in specifically to pitch to Oritz; it put the Sox up, 5-2 (but the horrific ending rendered it futile);
... Game 7 ALCS '04, top of the 1st, off Brown; it put the Sox up, 2-0, and silenced the crowd, coming immediately after Damon was thrown out at the plate. This showdown turned into a bombastic blowout, but Papi's HR gave Boston a lead it never relinquished, so technically it was his fourth game-winning hit of this postseason.
