This is a true toss-up by the numbers. Both squads have posted nearly identical scoring differentials, and the outcome will likely hinge on which team executes better in crunch time.
The offensive edge belongs to Nationals at 5.3 PPG, a number that sits well above the 4.5 PPG the Diamondbacks defense allows. Look for the home team to push the pace and attack early. Meanwhile, Diamondbacks scores 4.5 PPG but faces a Nationals defense that limits opponents to 5.3 PPG. The home team's defensive effort could be the difference-maker. Both teams' offenses closely mirror what the opposing defense allows, suggesting a game that plays close to each team's season averages. The team that gets stops on key possessions will pull ahead.
Home court advantage is worth approximately 3.0 points in MLB, and Nationals will look to leverage their home crowd. Our model has this nearly dead even at 0.3 points. These razor-thin margins mean the game will likely come down to late-game execution and free throws.
