The Red Sox challenged the play for obstruction and Kiner-Falefa's run was overturned.
Belt hit two-run and solo shots, Kevin Kiermaier and George Springer had two-run homers and Bo Bichette added a solo blast in the rubber match of a three-game series.
The loss broke the Braves' five-game winning streak and handed them their first home loss in eight games this month.
Maikel Garcia's run-scoring single and Drew Waters' RBI groundout got them within a run with the tying run on second.
Yoan Moncada hit a two-run double that tied the game and Oscar Colas made it 7-5 with a two-run double during the seventh-inning uprising.
