Overview
- Manager Oliver Marmol confirmed late Saturday that Brycen Mautz will make his major-league debut on Sunday, May 24, 2026, when he starts the series finale against the Cincinnati Reds.
- Mautz comes up from Triple-A Memphis after posting a 2.90 ERA in nine starts this season with 43 strikeouts in about 40 innings and a 24-walk total that managers will watch closely.
- The club pushed the lefty into the rotation after a rainout and heavy starter usage forced the Cardinals to add a sixth starter to give regular rotation arms extra rest.
- Scouts note Mautz throws from a low three-quarters slot that creates deception and a flat fastball angle, and he was the Cardinals’ 2025 Minor League Pitcher of the Year and a 2022 second-round pick.
- This call-up continues St. Louis’ pattern of using the farm system to fill short-term rotation needs and could affect upcoming starts in Milwaukee by shifting scheduled turns for Matthew Liberatore, Michael McGreevy and Dustin May.
