Astros Recall Miguel Ullola for Major‑League Debut

Overview

• Ullola was recalled from Triple‑A Sugar Land for his MLB debut, a report first published Saturday and confirmed to the Houston Chronicle by a person with knowledge.
• Because Ullola is already on the 40‑man roster the club only needed to alter its 26‑man active roster to add him for Sunday’s game.
• The 24‑year‑old right‑hander was converted from starter to full‑time reliever this season to help his command and has a mid‑90s fastball plus a five‑pitch mix that produced a high strikeout rate in the minors.
• Houston optioned Kai‑Wei Teng to Triple‑A to create the roster spot, a move the team framed as a planned workload de‑load after Teng described some fatigue and struggled in his most recent start.
• Ullola’s promotion reflects the Astros’ focus on managing starter innings and shoring up an overused bullpen while they monitor whether shorter relief stints improve his control.
