Between Friday morning and Saturday evening (and perhaps beyond), you're going to hear a great deal about momentum. Me? I don't put a great deal of stock in it. Not in baseball. If momentum's so important, then how did the Red Sox come back from seven runs down in the first place? Shouldn't they have just rolled over, those last few innings? Because the Rays had as much momentum, in both the series and the game, as you'll see a team have. Does the Red Sox's newfound momentum mean more, because they've been in this spot before? Perhaps. I'm smart enough to know there are things I don't know. But in this case, what I don't know will likely be smashed by the starting pitchers in Game 6.
