Griffin Canning worked behind an opener on Wednesday in St. Louis, earning the win with 4 1/3 innings of one-run ball.

Canning struck out two while walking three and allowing four hits on the afternoon. His ERA now sits at 6.64, and his role in the San Diego rotation is up in the air with Germán Márquez possibly back from the IL next time through. Canning’s start would come at home against the Braves if he winds up making it.
