Astros Finalize Opening Day Roster

The Astros finalized their Opening Day roster, most announcing that shortstop Jeremy Pena will avoid a season-opening trip to the injured list. Catcher César Salazar was designated for assignment, clearing a 40-man roster spot for Christian Vázquez, whose contract has been selected from Triple-A Sugar Land. Houston also selected right-hander Christian Roa‘s contract and opened a 40-man spot by placing lefty Brandon Walter on the 60-day IL while he recovers from UCL surgery. Houston also optioned outfielder Zach Cole to Triple-A, while prospect Brice Matthews makes the cut.

Outfielder Zach Dezenzo will open the season on the 10-day IL due to a right elbow sprain. Righty Ronel Blanco (recovering from Tommy John surgery), left-hander Josh Hader (biceps tendinitis), righty Enyel De Los Santos (right knee strain), lefty Bennett Sousa (oblique strain), right-hander Nate Pearson (recovering from elbow surgery) and right-hander Hayden Wesneski (recovering from Tommy John surgery) are all opening the year on the 15-day IL. Blanco and Wesneski will be 60-day IL candidates whenever Houston next needs a 40-man roster spot.

Pena’s status was up in the air after he suffered a fracture on the tip of his finger while fielding a grounder during an exhibition contest earlier this spring. He resumed hitting earlier this week, however, and has been deemed healthy enough to break camp with the club.

Vázquez’s selection to the big league roster was already known, as was the fact that Salazar wouldn’t make the team. Today’s DFA doesn’t necessarily mean that the ‘Stros won’t be able to find a trade partner. He can still be swapped out to another club within the next five days if another team is willing to put him on its 40-man roster.

Salazar, 30, has 67 MLB plate appearances to his name and has batted .232/.318/.268. He spent the bulk of the 2025 season in Triple-A, where he hit .213/.353/.353. He’s regarded as a solid defender but not the same extent as the veteran Vázquez, so Houston — as they’ve done in the past with Martin Maldonado — will opt for a plus defender as their backup catcher even if it means rostering one of the lightest-hitting players in the game.

Roa, 26, made his MLB debut with Miami last season and tossed three shutout innings. He’s a former Reds and Marlins farmhand who had a dominant spring with Houston after signing a minor league deal in December. He tossed 9 2/3 innings of one-run ball during Grapefruit League play and punched out 36% of his opponents without issuing a walk. Between that and last year’s 2.83 ERA in 60 1/3 Triple-A frames, he could be a nice under-the-radar pickup for the Astros.

Cole looked to be in strong position to make the club entering camp, but Houston reacquired Joey Loperfido to give them another lefty option in the outfield. Cole slashed .200/.340/.400 in 50 spring plate appearances, and the alarming contact issues that plagued him last year weren’t any better in March. After going down on strikes in 35% of his minor league plate appearances and 38.5% of his big league plate appearances in 2025, Cole punched out in 20 of his 50 turns at the plate this spring (40%).

Cole has obvious power and speed but will need to make more contact if he’s to carve out a a lasting role. Add in a handful of lefty opponents for Houston early in the season, and the right-handed-hitting Matthews will get the nod to begin the year. Matthews is a former first-round pick who slashed .250/.400/.417 this spring. He struggled in a brief MLB debut last year but hit .260/.371/.458 in Triple-A. While Matthews was drafted as a shortstop, the Astros’ glut of infielders has pushed him into outfield duty.
