The Houston Astros have suffered a significant blow behind the plate, as catcher Yainer Diaz has been sidelined with a left oblique strain. The team placed the 27-year-old on the 10-day injured list Tuesday, following an injury sustained during batting practice the day before. Manager Joe Espada didn't offer a specific timeline for Diaz's return, but acknowledged the injury would keep him out "for a while."
Diaz had been a key contributor for Houston this season, posting a .248 batting average with two home runs and 14 RBIs in 26 games. His absence leaves a noticeable gap in the lineup, especially given his emerging reputation as one of the game's promising young catchers. Oblique strains can be tricky for hitters, often requiring careful rehabilitation to avoid re-injury, so the Astros are taking a cautious approach.
To fill the void, Houston selected the contract of catcher César Salazar from Triple-A Sugar Land on Monday. Salazar will serve as the backup, while veteran Christian Vázquez steps in as the primary starter. The team is banking on Vázquez's experience to steady the ship during Diaz's recovery.
The Astros also made several other roster moves Tuesday. They recalled right-hander Jason Alexander and outfielder Zach Dezenzo from Sugar Land, adding depth to both the pitching staff and the outfield. Infielder Nick Allen was reinstated from the 10-day injured list, providing a boost to the infield. Meanwhile, right-hander Ryan Weiss was optioned to Triple-A after a tough start to the season—he's 0-3 with a 7.62 ERA in nine appearances, including a rough outing Monday night where he allowed seven runs in 4⅓ innings against the Dodgers.
In a separate move, the Astros designated outfielder Dustin Harris for assignment. Harris, who was claimed off waivers from the Chicago White Sox on April 18, struggled to find his footing, hitting just .226 with four RBIs in 11 games.
For Astros fans, the focus now shifts to how the team adapts without Diaz. With Vázquez taking the reins and Salazar ready to step in, Houston will look to maintain its competitive edge while waiting for their young catcher to heal.
