Josh Hader Injury: Nursing shoulder issue

Astros manager Joe Espada said that Hader wasn't available to pitch in Monday's 7-6 victory over the Red Sox due to left shoulder discomfort, Chandler Rome of The Athletic reports.

Espada didn't specify whether Hader will require a stint on the injured list due to the shoulder issue, as the Astros will sent the closer in for further tests before deciding his next steps. While Hader was unavailable Monday, the Astros sent right-hander Enyel De Los Santos to the mound to begin the ninth inning, and he retired two of three hitters before being pulled in favor of lefty Bennett Sousa, who struck out the left-handed-hitting Roman Anthony to secure the save.
