Instead, it was Hyun-Jin Ryu with a spotless start as the Dodgers cut St. Louis' series lead to 2-1 with a 3-0 victory on Monday.
Ryu struck out four batters and gave up just three hits and a walk over seven innings.
Adrian Gonzalez took a Wainright pitch up the first base line to score Mark Ellis for the opening run in the fourth inning. Yasiel Puig followed that by legging out a triple that scored Gonzalez.
Hanley Ramirez, who was questionable before first pitch with a rib injury, scored the final run as he plated Crawford with a bloop single in the eighth.
Wainright lasted seven frames, allowing two runs on six hits while striking out five batters.
Lance Lynn will square off against Ricky Nolasco in Game 4 on Tuesday.
