I did not watch this game and I don't doubt the atmostphere was electric. However, I would go with 1989 (which I attended). Cal had a three run homer off Clemens, O's win in extras. I believe the winning play was one of those unusual situations (1st and 3rd, 1 out, game on the line) where the Sox went with a six man infield but Worthington was able to get a ball in the outfield to win the game. Was also significant because we started '88 with the Other Streak and this started us off as winners which carried through into a miraculous season.
