Philadelphia Phillies at Washington Nationals
The Phillies head to Washington with Zack Wheeler on the mound, and his numbers stand out against most starters this late in the season. Wheeler has thrown approximately 143.3 innings with a 3.14 ERA and a WP-calculated FIP of 3.61, a strong combination of run prevention and peripheral performance. Jared Simpson starts for the Nationals with a much smaller sample of approximately 4.0 innings pitched, carrying a 6.75 ERA, though his WP-calculated FIP of 3.42 is actually a touch better than Wheeler's mark, which suggests his results so far have not matched his underlying peripherals.
Looking at the team-level numbers, Washington actually holds the edge in projected offense with a WP-estimated wOBA of 0.325 compared to Philadelphia's 0.308. On the run-prevention side, though, the Phillies look considerably stronger as a staff, with a WP-estimated FIP of 3.89 and ERA of 4.01 against Washington's 4.79 FIP and 4.72 ERA. That gap in team pitching numbers is significant and lines up with Wheeler's individual profile as well.
Both clubs are dealing with reported injury situations. The Nationals have Tyler Baum, Connelly Early, and Josiah Gray each listed on the 60-Day IL, while the Phillies have Moises Chace and Adolis Garcia listed on the 60-Day IL and Nestor Cortes listed on the 7-Day IL. Taken together, the available figures favor Philadelphia, largely on the strength of Wheeler's individual performance and the team's clearly better staff-wide ERA and FIP figures, even though Washington's offensive wOBA number is the more favorable of the two.
