Josh Hader throws scoreless rehab inning

Josh Hader’s latest rehab outing was brief and efficient. The Houston Astros closer threw one inning for Double-A Corpus Christi on May 12, using 16 pitches, striking out one batter and allowing one hit, according to MLB.com. The appearance was part of Hader’s return from left biceps tendinitis, an injury that sent him to the injured list before the regular season and later to the 60-day IL. The Astros’ official injury report lists May 24 as his expected return date. ### Why was Hader pitching for Double-A Corpus Christi? Josh Hader joined Corpus Christi on a rehab assignment this week while working back from the biceps issue. The Corpus Christi Hooks said in a team release that Hader, shortstop Jeremy Peña and center fielder Jake Meyers were all scheduled to make rehab appearances at Whataburger Field. The Astros have used multiple affiliates during Hader’s rehab work. (mlb.com) MiLB.com also posted video from a May 5 outing for Triple-A Sugar Land and a May 9 appearance in which Hader struck out two batters during a scoreless inning, showing that the club has already built him through several game appearances before this stop in Corpus Christi. ### What exactly happened in the May 12 inning? (milb.com) MLB.com’s Astros injury page said Hader threw one inning on May 12 for Double-A Corpus Christi, struck out one batter and allowed one hit. The same update listed his pitch count at 16. FantasyPros reported the same line from the outing, describing it as a scoreless frame and saying Hader “continues to get closer to being activated.” That assessment was FantasyPros’ characterization, not a formal Astros announcement, but it matched the club’s use of a rehab assignment less than two weeks before the listed return date. (milb.com) (mlb.com) ### What injury is Hader returning from? The Astros listed Hader’s injury as left biceps tendinitis. MLB.com’s injury tracker said he was placed on the injured list on March 25 and transferred to the 60-day IL on April 17. MLB.com reported last week that Hader could not be activated before May 24 because of the 60-day designation. That roster rule gives the rehab assignment added context: even if Hader is physically ready sooner, Houston cannot reinstate him before the date tied to his IL status. (fantasypros.com) ### How much rehab work has he logged so far? MiLB.com’s player page for Hader showed 3.0 innings across three rehab appearances with Corpus Christi as of the latest update, with a 0.00 ERA and four strikeouts. (mlb.com) The same page identified his status as a rehab assignment. Those numbers suggest the Astros have kept Hader in short, controlled outings. The available game logs and video clips from Sugar Land and Corpus Christi show one-inning appearances rather than extended work, which is typical for a reliever building back from an arm issue, though the Astros have not publicly detailed a pitch-by-pitch progression plan in the material reviewed. (mlb.com) (milb.com) ### When could Hader rejoin Houston? May 24 is the date attached to Hader on the Astros’ official injury page. MLB.com repeated that expected return date in the club’s injury tracker updated May 12. The Astros were scheduled to play Seattle on May 14 and open a series against Texas on May 15, according to MLB.com’s scoreboard. Hader cannot come off the 60-day injured list until May 24, so his next steps are likely to remain on the rehab track until that date arrives or the club announces a change.
