New York Mets vs Washington Nationals Prediction — Sunday, September 27, 2026

New York Mets vs Washington Nationals prediction watchers are circling this Sunday, September 27, 2026 game at 1:05 PM ET for one reason: the pitching plan on both sides looks unstable. The desk's read lands on Washington at -110, but this one is a PASS — an official-card no-play, with no official action behind it.

That is not indecision. It is the result of running the actual bullpen math on both clubs and finding a split picture that does not clear the bar to back either side.

Why the bullpen workload matters here

Herz is on a 60-pitch pattern and projects for roughly four innings, which means the Nationals need five innings of relief to close this game out. That is a heavy lift for any pen, and this one has specific issues: a 4.2 walks-per-9 rate and 1.40 home runs allowed per 9. Extra baserunners plus extra fly balls out of the park is a combination that can turn a close game into a track meet in a hurry.

On top of the raw rates, two of Washington's relief options are compromised by recent workload. Lavender pitched in back-to-back games, and Hagenman threw 70 pitches on September 25. Neither is likely available today, which thins an already stressed pen even further right when Washington needs innings covered.

The case for New York

The Mets counter with a rested core in Nunez, Williams, and Myers, the trio the model expects to protect the late innings. A bullpen that has not been taxed in recent days is generally a cleaner bet in a game where the other side is patching together relief work, and that rest edge is real.

But rested arms on one side do not automatically clear a play on the other. The model still has to weigh the Nationals' moneyline price against what that bullpen math actually says about their odds of getting through five relief innings clean, and that is where this one stalls out.

Why this is a pass, not a play

To be direct: this is not a bet the desk is making today. The Nationals price out at -110 on the moneyline, and the pick sits at PASS, which is Botcappers' way of saying no official action is going out on this game. That is not a soft lean or a lower-confidence version of a play. It is simply off the board.

We are not going to name which specific threshold kept this one on the sideline, and we are not going to dress it up as almost a play. The bullpen workload numbers above are the real, concrete factors in the read. What they add up to, on this particular price, is a pass.

The verdict

Sunday's 1:05 PM ET game has enough moving parts to keep it interesting: a short Herz outing, a Nationals pen without its two most recently used arms, and a rested trio waiting in New York's bullpen. All of that goes into the read, and all of it lands on PASS. No bet today, and the box score will still tell the story either way.
