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.

More to come.
