The St. Louis Cardinals optioned pitcher Tyler Lyons to Triple-A Memphis on Saturday. The Cards called up reliever Michael Blazek in a corresponding move. Lyons left Friday's loss to the Rangers after giving up four runs on three hits and three walks in one-and-two-thirds innings. He is 2-and-3 with a 5.51 ERA with the parent club this season. Blazek posted a 2.31 ERA in eight appearances with Memphis this season.
