Phillies vs. Nationals Prediction: Wheeler Faces Washington’s Bullpen Game

Analysis updated September 16, 2026 at 5:08 AM CDT

Philadelphia is the pick to win, but Washington’s plan to use several pitchers limits what the opening matchup tells bettors.

Wheeler gives Philadelphia the edge

Zack Wheeler’s expected start is the strongest reason to favor Philadelphia at Washington on Sept. 16. Phillies Wire, a Phillies news site, lists him as the probable starter with a 12-5 record and 3.14 ERA. SPF prices the Phillies at -191, which requires roughly a 65.6% win probability to break even.

Washington’s pitching plan makes a straight ERA comparison less useful. CBS Sports / RotoWire reports that Jared Simpson will open a bullpen game to give Cade Cavalli additional rest. Simpson is expected to pitch only a few innings, so his 6.75 ERA describes just one part of the pitching Philadelphia will face.

Betting outlook

The winner lean is Philadelphia, with low confidence. Wheeler’s record and ERA support that choice, but they don’t establish that the Phillies clear the threshold for a worthwhile -191 wager. Phillies Wire also reports that starting lineups remain pending. The moneyline decision is Pass.

SPF lists Philadelphia at -1.5 runs and the total at 8.5, with both over and under priced at -110. Without a clearer picture of Washington’s relief innings and the batting orders, neither a winning margin nor a scoring projection is well supported. Pass on those markets too.
