Astros 5.12 ERA rotation problem could be a postseason nightmare

The Houston Astros are facing a significant pitching concern heading into the postseason, with their starting rotation posting a troubling 5.12 ERA as of August 18, 2026. The poor rotation performance has been identified as a potential major liability should the Astros advance to playoff competition.
