Despite the early exit of starter Max Scherzer, the Rangers grabbed a 2-1 lead in the best-of-seven series.
Scherzer, facing his former team, had been struck by a ball hit up the middle by the Diamondbacks' Alek Thomas in the second inning.
Jon Gray, who had been considered by Rangers manager Bruce Bochy to start Game 4, entered Game 3 in relief and earned the win.
The Diamondbacks had the first real scoring opportunity of the game in the bottom of the second inning, when Christian Walker led off with a double.
Jose Leclerc pitched a 1-2-3 ninth inning to earn his fourth save of the postseason for the Rangers, who finished with five hits.
