Suero was recalled from Triple-A Sugar Land on Tuesday, Matt Kawahara of the Houston Chronicle reports.
The Astros signed Suero to a minor-league contract in December. The right-hander surrendered seven earned runs in just eight innings at the major-league level with the Dodgers in 2023. In a corresponding move, Oliver Ortega (elbow) was transferred to the 60-day IL to create a 40-man roster spot for Suero.
