With the teams tied 1-1 entering the final inning, the Dodgers got their noses in front through Cody Bellinger's run-scoring single before a sacrifice fly from Austin Barnes scored another.
Pederson then smashed a homer to right field to give the Dodgers a five-run lead and silence the home crowd.
With the Astros down to their final strike, Alex Bregman homered to left but it proved too little too late as their unbeaten home stretch in the postseason ended at seven games.
Game Five is scheduled for Sunday in Houston.
