On a day where the wind is blowing straight out, a 4-run lead is nothing. For all the times the Cubs have come back from 2-3-4 run deficits early in the game, one would think that there would be occasions where the reverse would happen. Last I checked, though, the wind is still blowing out, and the Cubs are still the highest scoring team in the NL. Does that guarantee victory? Absolutely not. But it's not absurd.
