Wainwright struck out slugger Ronald Acuña Jr. with a runner at second to end the fifth and St. Louis leading 6-1. It was Wainwright's 26th career complete game, two of them this season.

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.

After rain postponed Saturday’s game to force the doubleheader, the Cardinals snapped a six-game road losing streak, their longest under fourth-year manager Mike Shildt.

The Braves, who play another doubleheader Monday at the New York Mets, have dropped seven of 10.

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.

TRAINER’S ROOM

Braves manager Brian Snitker had no update on the status of LHP Tucker Davidson, who avoided Tommy John surgery last week after being diagnosed with a forearm strain. “He’s in that shutdown phase where they’re just going to cool everything down for a while,” Snitker said.
