Adam Wainwright struck out 11 and pitched a three-hitter in going the full seven innngs, sending the St. Louis Cardinals over the Atlanta Braves 9-1 Sunday in the first game of a day-night doubleheader.

Nolan Arenado hit a two-run homer off Bryse Wilson in the first and Paul Goldschmidt added a three-run shot off Josh Tomlin in the fifth.

The 39-year-old Wainwright (5-5) didn't allow a hit until the fourth, when Freddie Freeman singled.

Wainwright struck out slugger Ronald Acuna Jr. with a runner at second to end the fifth and St. Louis leading 6-1. With his second complete game this season, Wainwright tied Justin Verlander for most overall among active pitchers.

Wainwright reversed a trend in which he was 1-2 with an 8.20 in four road starts this year. He also improved to 8-0 in 10 doubleheader starts.

Tommy Edman singled off Wilson (2-3) to begin the first and stole second base to set up Arenado, who snapped a 0-for-20 slump with his 13th homer. Tyler O'Neill doubled to start the fourth and scored on Yadier Molina's single.

Goldschmidt's 10th homer came on Tomlin's first pitch.
