The Boston Red Sox defeated the Atlanta Braves 4-3 on March 17, 2026, at JetBlue Park, converting what the DiamondIQ model estimated as a 31 percent pre-game home win probability into a certainty by the final out. Boston's offense broke through in the fourth inning with a three-run frame that proved decisive, with Nate Eaton's single off Reynaldo López delivering the key blow, adding 19.6 percent in win probability and posting a RE24 of plus-1.2 to anchor the rally. Atlanta had struck first with two runs in the third, but the Red Sox answered emphatically and never relinquished the lead.
The game's tension carried into the ninth inning, where the Braves mounted a threat against Kyle Keller before falling short. Jake Steels' strikeout swung the win probability 20.4 percent in Boston's favor, and though Jordan Groshans immediately answered with a single that swung it back 20.4 percent in Atlanta's direction, Colby Jones followed with a groundout that cost the Braves 12.7 percent, extinguishing the rally and closing out Atlanta's hopes. Groshans finished as Atlanta's most impactful offensive contributor despite the loss, posting plus-20.4 percent WPA and a RE24 of plus-1.0.
On the pitching side, Payton Tolle was the most valuable performer of the night by a significant margin, contributing plus-28.9 percent WPA for Boston, while Dylan Dodd and Zack Kelly each added meaningful contributions at plus-7.3 and plus-7.2 percent respectively. Carlos Narváez rounded out Boston's offensive effort with plus-15.7 percent WPA and a RE24 of plus-0.8. The Red Sox finished with six hits to Atlanta's nine but executed when it mattered most, leaving the Braves unable to overcome a critical fourth-inning deficit.
