Washington Nationals vs Philadelphia Phillies — Mar 31, 2026 | AI Prediction & Stats

Washington enters on a roll and draws a favorable matchup against rookie Andrew Painter, who is making both his big-league and season debut. Painter’s stuff is electric, but the lack of major-league seasoning and a strict pitch limit should cap him at four innings. The Nationals’ right-heavy heart of the order—House, Wiemer, Ruiz—has been driving the ball with authority and should capitalize early; expect two quick runs in the first on a House double and a Ruiz sac-fly. Zack Littell gives the Nationals five solid frames. He pounds the zone, leveraging a splitter that neutralizes Philly’s lefties. The Phillies scratch out a run in the second when Bohm lines a single after a Marsh double, but Littell strands runners twice with ground-ball outs. Once Painter exits, Philadelphia’s middle relief (Pop/Backhus) is exposed again. A third-inning solo shot by Wiemer and a fourth-inning Abrams RBI single push Washington’s lead to 4-1. Tim Mayza and José Alvarado quiet things in the sixth, yet Jake Irvin and Clay Beeter match them, bridging Washington’s bullpen to the late innings. The Phillies briefly surge in the fifth when Schwarber ambushes a Littell cutter for a two-run homer, trimming the deficit to 4-3. Littell exits, but Cole Henry strands the tying run. Washington answers in the seventh on a Daylen Lile RBI flare off Zach Pop, and adds an insurance run in the eighth when CJ Abrams legs out an infield single, steals second, and scores on a Nasim Nuñez bloop. Philadelphia plates one more in the seventh—Marsh’s hustle double followed by a Stott RBI single—yet Foster Griffin and Clayton Beeter lock it down. Beeter’s two-inning save features a 99-mph fastball that freezes Harper to end the eighth and a swinging strikeout of Schwarber in the ninth. Nationals 6, Phillies 4. Washington’s balanced offense and deeper bullpen offset Philadelphia’s home-field edge, while the rookie learning curve for Painter proves decisive.
