What about it being ominous for the Red Sox? Their No. 1 pitcher was trash-talking up a storm about how he was going to shut up 55,000 fans, and he ended up skulking out of the game after three innings. And their No. 2 starter calls the Yankees his daddy. If you're going to extrapolate all sorts of sordid implications for the Yankees, then you should do the same for the Red Sox. I say it's just one game, and I'm not going to read anything into it for either team or for the series, other than the Yankees getting a W in one game.
The Yankee victory in Game 1 should be the most ominous sign of all. They usually lose when they win the first game, don't they?
