Nationals vs Mets Prediction 20 May 2026
π‘ Washington and New York have already produced two high-scoring games in this series: the Mets took the opener 16-7 before the Nationals bounced back with a 9-6 win. The third matchup also shapes up as a solid opportunity to back the over, with the hosts sending Zack Littell to the mound-he carries an ERA north of 7.00-while the visitors counter with Zack Thornton, who has a limited track record at this level. This prediction for a high total is based on both teamsβ strong offensive form and the inconsistency of the starting pitchers.
Head-to-Head
π Washington have taken six of the last ten head-to-head meetings. Nationalsβ wins: 9-6, 5-4, 14-2, 3-2, 5-3, 9-3. Metsβ victories: 16-7, 8-0, 12-6, 8-1. In five of those ten games, the teams combined for at least ten runs, and the first two games of the current series have already produced 23 and 15 runs. This context is crucial for the over: these teams donβt just explode in a single inning, but rather keep trading blows throughout the game.
Head-to-head statistics Nationals - Mets

Washington Nationals Team Overview
Washington remain one of the most reliable teams for high-scoring games this season. The hosts know how to put runs on the board: they've already racked up 16 runs in two games of this series, proving they can bounce back even after a tough loss. However, their pitching continues to be a major concern, frequently giving opponents plenty of opportunities. The Nationals are capable of pushing the total over on their own, but they almost always leave the Mets with a chance to respond with a big inning of their own.

New York Mets Team Overview
The Mets haven't always shown consistent offense over the long haul, but they've quickly found their groove against Washington. Scoring 16 runs in the series opener was no fluke-itβs a clear sign of just how comfortable the visitors feel facing this pitching staff. In Game 2, they put up another six runs, proving their bats are still making solid contact. For the total to go over again, New York don't need another 16-7 blowout; a few productive innings should be more than enough.

βΎ Starting Pitchers
Zack Littell gets the nod for Washington, coming in with a 7.07 ERA. That number is a major red flag for anyone considering the over-Littell has struggled to give the hosts a clean start, frequently pitching under pressure with runners on base. Against the Mets, who have already twice put him under the cosh in this series, heβll need to sharpen his command in the zone. If Littell allows early baserunners again, Washington could find themselves in another high-scoring contest before long.
New York counters with Zach Thornton, who boasts a spotless 0.00 ERA-but that stat comes from a tiny sample size and shouldnβt be taken as a sign of reliability just yet. Washingtonβs hitters are seeing the ball well, capitalizing on mistakes, and have already shown they can get to Mets pitching. Thornton will have to navigate a red-hot lineup without handing out free passes or leaving anything over the heart of the plate.
β Editorβs Prediction
The 9.5 total is certainly high, but recent games have set the bar for offensive fireworks. We've seen two straight matchups turn into slugfests, with both teams finding ways to score-whether it's via the long ball, traffic on the basepaths, or putting pressure on the relievers. Littell comes in with an ERA north of 7.00 and hardly looks like the kind of starter who can suddenly shut down the Metsβ lineup. Thornton may boast a zero ERA, but his sample size remains limited and questions linger. Washington are swinging the bats aggressively at home and should be able to contribute their share, while New York have already shown they can handle this pitching staff. Even if the opening innings are cautious, both bullpens could be in for another heavy workload as the game progresses. All signs point to over 9.5 runs as a reasonable prediction here.
