Mets vs Nationals ATS and Total Picks
- Run Line: Washington +1.5
- Total: Over 10
Washington's lineup has the depth, power and on-base ability to make Christian Scott work and keep this game close, especially at home where the Nationals have multiple paths to crooked innings. Even if New York wins, the margin should stay tight, making Washington +1.5 the right side. On the total, Jake Irvin's 5.91 ERA, combined with both starters carrying WHIPs above 1.40 and a Nationals offense averaging well over five runs per game, supports the over at 10.
Final Score Prediction
- Washington 6, New York 5
Expect Abrams and Wood to do enough damage early to keep Washington in front, with Soto and Vientos pulling the Mets back into the game in the middle innings. The Nationals' lineup depth carries them across the line in a high-scoring game that clears the total and covers +1.5 with room to spare.
