Arenado (back) is serving as the Cardinals' designated hitter and batting cleanup Thursday versus the Astros.

EDGE Analysis

Arenado has been bothered by lower-back tightness since Tuesday and made an early exit from Wednesday's game because of it, but he feels well enough to fill the DH role in Thursday's series finale versus Houston. Nolan Gorman will cover third base and Brendan Donovan is playing second base.
