The Cubs had a 0.6 percent chance of beating the Braves in the 7th inning. An hour or so later, the Cubs won the game. Easily.
Javy Baez’s bases-clearing double that tied the game at 10-10 in the 8th inning was worth 44 win expectancy percentage points. You don’t need the math to get that Javy’s knock was the most clutch of the season. Heck, it might very well end up being the most clutch hit of the entire season come October.
All in all, the Cubs entered the bottom of 8th inning with a three percent chance of winning the game and ended the frame with a 99 percent chance of winning.
