Zack Littell has had a rough 2026 on paper: 6.10 ERA, 14 home runs in 41.1 innings, a 3.05 HR/9 rate that makes every power hitter at-bat uncomfortable. His command hasn't been clean either, posting 20 strikeouts against 15 walks across those innings. His April 28 start against these same Mets was a 4-run disaster in 3.2 innings. But his most recent outing tells a different story: 5.0 scoreless frames against Baltimore on May 15, showing some stabilization in his overall approach. He takes the mound tonight on five days of normal rest, which is the most composed version of Littell bettors will see this year.

This is Game 3 of a wild series. Game 1 went 16-7 Mets. Game 2 went 9-6 Nationals. That is 39 runs in two games at this exact ballpark. Both bullpens have been taxed. Butera acknowledged the grind after recalling Dylan Crews and Andrés Chaparro from Triple-A: "It'll give Woody and Daylen some DH days, which will be nice. They've been playing a ton, they've been on their feet a ton." Crews, the 2023 second-overall draft pick, went 1-for-4 in Washington's Game 2 win and brings hot minor-league form (.308 over his last 17 games, .585 SLG) into a lineup already loaded against southpaws.

Nationals Park is as neutral as ballparks get, with a runs factor of 1.0 and an HR factor of 1.02. The environment won't inflate or suppress tonight's total on its own. What shapes this game is whether Thornton survives a right-handed Washington lineup hunting lefties in the early innings, and whether Littell's recent stabilization holds against a Mets squad that is 10-14 on the road but has won five of its last six overall.

• Washington is 10-5 against left-handed pitching in 2026; New York is 3-10. That is one of the most lopsided platoon splits in baseball, and it is the structural edge underneath every pick in this game.
• Zack Littell has surrendered 14 home runs in 41.1 innings (3.05 HR/9) with a 6.10 ERA and only 20 strikeouts against 15 walks. He is a pitcher bettors should treat as a walking run-scoring opportunity until his performance suggests otherwise.
• Game 3 of 3. The first two games in this ballpark produced 16-7 and 9-6 final scores (39 combined runs). Both bullpens arrive tonight already taxed, which matters enormously when either starter struggles early and a quick hook is the only answer.
• Thornton has no available MLB career statistics, and no Washington hitter carries any data against him. That unknown cuts both ways: he could be pulled by the third inning if he struggles, immediately exposing a thin Nationals bullpen, but the historical odds favor the known lineup over the unknown pitcher when the platoon advantage is this pronounced.
• Bo Bichette owns a career .429 average and 1.152 OPS across 16 PA against Littell, the single clearest batter-vs-pitcher edge in this game's data. His 2026 sample against Littell is tiny, but the trajectory has been consistently violent.
• Brady House, Washington's most productive hitter against left-handed pitching this season (.354 average, .988 OPS vs LHP), was optioned before this series. His absence removes their top individual southpaw masher from the lineup, though the team's 10-5 record vs LHP shows depth at that platoon advantage throughout the roster.

If totals are your preferred lane, the environment here is about as favorable for an over play as you'll find without a model projection to lean on. Both bullpens are thin after two high-scoring games in this same ballpark. Thornton faces a quick hook if he stumbles early. Littell surrenders home runs at an extraordinary rate. The series has already produced 39 runs in two games. The Over 9.5 at -125 is the honest, if lower-conviction, play that the qualitative data supports. Juan Soto's +260 home run prop rounds out the value column for a hitter who carries confirmed HR history against this pitcher and owns a 1.031 career OPS against him.

The caveat is real. The Mets are playing well, winning five of their last six games, and A.J. Ewing's .500 OBP gives the top of their order a spark it lacked earlier in the year. Nothing about this game is a lock. Littell's ERA remains a liability in every start. But at plus-money, the Nationals ML doesn't need to be a lock. It needs to be right more than 48% of the time. The platoon split, the Thornton unknown, and the run environment tonight make that a reasonable proposition. For the full slate, see our MLB picks today, NRFI picks, and player props.
