The Astros designated Solis (elbow) for assignment Tuesday, Jake Kaplan of The Athletic reports.
Solis' spot on the 40-man roster will go to utility man Niko Goodrum, whose one-year contract with the club was finalized in a corresponding move. A 22-year-old right-hander, Solis was once one of the more promising lower-level prospects in the Astros' system, but he hasn't made a minor-league appearance since 2018 after undergoing two Tommy John surgeries. He had his most recent procedure last June and can presumably be ruled out for the entire 2022 campaign.
