New York Mets vs Washington Nationals Predictions Today: Sean Manaea vs DJ Herz

Game time: September 27, 2026 at 1:05 PM ET

Venue: Nationals Park — Washington, District of Columbia

Article updated Sep 27, 12:05 AM EDT

By SportsJaw Editorial Team

The New York Mets will beat the Washington Nationals, with a projected score of Mets 5, Nationals 4. New York's stronger season bullpen numbers and Sean Manaea's recent control give it a slight pitching advantage against DJ Herz. Washington's better scoring average and New York's recent relief workload keep confidence low. The supplied prices offer no compelling wager; the official recommendation is Pass.

New York Mets vs Washington Nationals prediction and best bet

New York is the pick because its pitching offers the more convincing route through nine innings. Manaea struck out 19 and walked two across his three dated September starts, while the Mets' bullpen has a 3.76 ERA against Washington's 5.03. Herz enters with only four innings of major league work this season, leaving considerable uncertainty around Washington's starting assignment.

That advantage is narrow. The Nationals average 5.06 runs per game, and Manaea's longer recent stretch has been uneven. New York's relievers also worked 15⅔ innings over their last three games. Forecast a Mets victory, but pass on the supplied run lines and total rather than stretch a fragile edge into a bet.

Odds, game time and how to watch

Game: MLB, Sunday, September 27, 2026, at 1:05 p.m. EDT.

Venue: Nationals Park.

Broadcast: SNY and Nationals.TV.

Probable starters: Left-handers Sean Manaea for New York and DJ Herz for Washington.

Records: Mets 74-87; Nationals 76-85. New York won September 26 by 7-1; Washington won September 25 by 7-6.

SportsJaw moneylines: Mets -113; Nationals -107. Run lines: Mets -1.5 (+150); Nationals +1.5 (-179). Total: Over 8.5 (+100); Under 8.5 (-120).

New York Mets outlook

MLB lists Manaea's 2026 season at 6-7 with a 4.67 ERA, 1.30 WHIP and 141 strikeouts in 144⅔ innings across 32 games. Covers reports different season totals, including 138⅔ innings and a 4.74 ERA; this assessment uses MLB's official season line. The dated outings provide a clearer comparison of his recent work.

At Texas on September 22, Manaea allowed three hits, three runs and two earned runs in six innings, walking two and striking out nine. Against Baltimore on September 15, he allowed four hits and two earned runs in 5⅓ innings, with six strikeouts and no walks. At Miami on September 8, he surrendered five hits and four earned runs in five innings without a walk.

Those starts suggest improved control, but his official seven-game split remains a 6.08 ERA in 40 innings. New York averages 4.32 runs per game, so its offense offers less season-long support than Washington's. The bullpen's 1.22 WHIP and .231 opponent average strengthen the Mets' case, although its recent workload makes it risky to assume every preferred reliever will be available. The pitching advantage needs Manaea to carry a meaningful share of the game.

Washington Nationals outlook

Washington's strongest argument is its offense. The Nationals average 5.06 runs per game, compared with New York's 4.32, and scored seven in the September 25 meeting. Saturday's one-run output shows why neither series result should dictate Sunday's forecast. Their season scoring rate is the more substantial reason to expect resistance against Manaea.

Herz returned from the 60-day injured list on September 21. He missed the entire 2025 season after Tommy John surgery in April, and his only 2026 start came at Detroit on the day of his activation. He worked four innings, allowing five hits, four runs, all earned, one home run and two walks while striking out four.

That leaves Herz with an 0-1 record, 9.00 ERA and 1.75 WHIP. Four innings are far too few to treat that ERA as his established ability, but they also offer little reassurance about how much work he can cover Sunday. Washington's relievers have a 5.03 ERA, 1.45 WHIP and .260 opponent average, with 4.1 innings per game. If Herz exits early again, the Nationals would ask a bullpen with weaker season results to protect a larger portion of the contest.

Key matchup factors

The central question is how much of New York's season bullpen advantage survives its recent workload. An efficient Manaea outing would reduce that concern; an early exit would make Washington's offensive advantage more influential. Both probable starters throw left-handed, but there is no verified offensive split here that earns either lineup an additional matchup adjustment.

SportsJaw's blended moneyline consensus favors Washington at 54 percent. Its combined modeled sample has 325 Washington selections and 277 New York selections, totaling 602. These are modeled equivalents combined with SportsJaw participation, not observed sportsbook ticket counts. The sportsbook component favors New York at 57 percent. That divided sentiment neither measures either team's win probability nor supplies a reason to fade Washington.

New York Mets vs Washington Nationals spread prediction

Pass on Mets -1.5 (+150) and Nationals +1.5 (-179). The projected one-run New York victory favors Washington's run-line outcome, but the -179 price demands more certainty than this matchup offers. Herz's limited workload and the Nationals' bullpen performance create a credible path to a larger Mets margin.

Conversely, New York's better relief statistics do not make a multi-run victory the likely result. Washington's scoring rate and Manaea's seven-game struggles leave too much room for a tight finish. Neither run-line price earns an official recommendation.

New York Mets vs Washington Nationals total prediction

Pass on Over 8.5 (+100) and Under 8.5 (-120). The nine-run projection sits half a run above the total. Washington's offense, Herz's difficult return and New York's bullpen workload all create scoring opportunities, but that small projected difference is not enough to justify the Over.

Manaea's recent strikeout-to-walk results and New York's stronger season relief numbers offer the opposing case. SportsJaw's community total leader is Under 8.5 (-120), but that preference is separate from a scoring forecast. The uncertainty around innings distribution makes either direction difficult to price confidently.

New York Mets vs Washington Nationals projected score

Game forecast: Mets 5, Nationals 4. New York gets the nod on Manaea's recent control and a bullpen that has allowed fewer baserunners across the season. Washington can overturn that forecast with the offensive production reflected in its higher runs-per-game average, particularly if Manaea's broader recent problems return.

Confidence is low because the Mets' relief workload complicates their strongest supporting advantage, while Herz's single start leaves a wide range of plausible outcomes. The forecast identifies New York as the likely winner without claiming a clear betting edge. Both run lines and the 8.5 total are a Pass. The single official SportsJaw betting recommendation is Pass.
