Josh Hader’s rehab shifts to Triple-A as Astros monitor velocity
Josh Hader’s first rehab inning hit 94.7 mph, and the Astros may have up to five more outings to judge his return.
Josh Hader’s first step back already gave Houston a number it wanted to see: 94.7 mph. The Astros closer worked a scoreless inning in Triple-A Sugar Land, allowing one walk and striking out one batter as he continued his return from left biceps tendinitis.
That outing came at Constellation Field in Sugar Land, where Hader has started rebuilding his arm strength after opening the season on the injured list. He averaged 94 mph on 11 fastballs, a useful checkpoint for a pitcher whose value is measured as much by late-inning certainty as by results. Hader, 32, had been shut down by biceps inflammation and was not eligible to come back until May 24 because he had been moved to the 60-day injured list on April 17.
The rehab assignment is now the Astros’ clearest countdown to the back end of the bullpen changing again. Hader was slated to throw one inning in relief on May 27 and another on May 28 in Sugar Land, giving Houston a chance to watch how his velocity held up and whether the command came with it. MLB.com reported he could have as many as five more minor league outings before returning, which points to early June as the likeliest window for activation if the arm keeps responding.
Houston has already had to lean on Bryan Abreu in the ninth inning while Hader works back. Abreu was expected to handle closing duties until Hader returned, a setup that has kept the Astros from having their full late-game structure in place for the opening stretch of the season. Hader also missed the end of last season, so this return is not just about getting one arm healthy again. It is about restoring the reliever Houston built its ninth inning around.
For Sugar Land, the assignment has become a high-stakes stopover. The Triple-A affiliate is giving Hader innings against live hitters while the Astros track whether the velocity, the slider, and the recovery all line up. If the radar gun keeps flashing close to 95 and the next outings stay clean, Houston’s bullpen hierarchy could shift quickly once Hader is ready to leave Constellation Field behind.
