Josh Hader's shoulder injury would keep him out of the regular season but he says he could be ready if Astros make playoffs.

Houston Astros closer Josh Hader has been diagnosed with a left shoulder capsule sprain and will be shut down from throwing for "approximately three weeks," the team announced on Friday afternoon. The Astros will determine Hader's next steps once that period passes.

At the end of the day, fatigue is fatigue,” the Astros' closer said. “The only way you can recover from fatigue is rest."
