Astros Notes: Hader, Alvarez, Arrighetti

Astros general manager Dana Brown shared some injury updates earlier this week at the GM Meetings, including the rather troubling news that Isaac Paredes is no guarantee to be ready for Opening Day.  Brown provided some more positive news with Matt Kawahara of the Houston Chronicle (multiple links) on some of the many other Astros players who missed significant time during the club’s injury-plagued 2025 campaign, as all of Josh Hader, Yordan Alvarez, and Spencer Arrighetti are expected to be ready for Spring Training.

Hader’s season was ended in early August by a right capsule sprain in his right shoulder.  There was some initial hope that Hader could potentially return during the playoffs, but he still hadn’t started throwing by season’s end, so it seemed unlikely that the closer would’ve been available even if Houston had reached the postseason.

Brown didn’t yet have a timetable on Hader’s recovery at his end-of-season press conference, but said this week that Hader has now thrown off a mound three times.  The plan is for Hader to have his regular winter throwing program and “hopefully, we’ll get him ramped up sometime early to mid-February…he’s on course to come back and be there for Opening Day,” Brown said.

As Rome noted, losing Hader ended up devastating Houston’s relief corps.  Hader had been the anchor of the bullpen, posting a 2.05 ERA, 36.9% strikeout rate, and 7.8% walk rate across 52 2/3 innings while closing down 28 of 29 save opportunities.  While Bryan Abreu performed respectably well in Hader’s place, losing a star closer further thinned out a bullpen that was already missing other arms due to injury, and it added to Houston’s mountain of health woes.

Having Alvarez for only 48 games was perhaps the most impactful of all the Astros’ injuries.  The three-time All-Star was sidelined mostly by a hand sprain that was eventually revealed as a finger fracture, and persistent hand discomfort kept Alvarez out of action from early May to late August.  While he posted great numbers upon his returning, Alvarez was shut down again by a left ankle sprain in mid-September that left him unable to even resume basic running or hitting drills by the end of the season.

The good news is that Brown said Alvarez should have “a normal offseason,” and is back to running at around “65-70 percent” of his usual capability.  Speed is not exactly a huge aspect of Alvarez’s game and he should continue to be Houston’s primary DH in 2026, but keeping an elite bat healthy is naturally a huge factor in the Astros’ hopes of future success.

Arrighetti was limited to seven starts and 35 1/3 innings in 2025, as he missed four months of action after his right thumb was fractured by a batted ball during batting practice.  That fluky injury was followed up by a bout of elbow inflammation that shut Arrighetti down for good in early September.  There was some concern raised when Arrighetti was set to go for a second opinion on his elbow, but it would appear as though he has gotten a clean bill of health for regular offseason prep.

For now, Arrighetti is penciled into a spot in Houston’s Opening Day rotation, though Brown has been open about the Astros’ desire to add to their pitching staff.  With Framber Valdez potentially leaving in free agency and several other Astros pitchers besides Arrighetti also on the mend, acquiring another starter would help clear up some of the uncertainty surrounding the pitching staff.
