Of the Cubs’ 51 wins this season, 28 have come after trailing at some point in the game. There are obviously some early 1-0 deficits in there that may seem insignificant, but consider that scoring a run in the 1st inning as the visiting team gives you a 56 percent chance to win. Doing so as the home team increases those odds to 70 percent. As you can see, scoring first is the best way to ensure a W.
It’s even better to be up either late or big, situations the Cubs have had to overcome more than once each already.
