10:15am: The promotion is now official. St. Louis optioned right-hander Matt Svanson<\/a> to Triple-A to clear a spot for Mautz.<\/p>\n

9:45am: Cardinals left-hander Brycen Mautz<\/a> will be called up for his MLB debut on Sunday, relays Derrick Goold of the St. Louis Post-Dispatch<\/a>. He\u2019ll slide into the rotation with St. Louis coming off a doubleheader on Saturday.<\/p>\n

It\u2019ll be the second straight day with a big-league debut for the Cardinals, who promoted<\/a> infielder\/outfielder Bryan Torres<\/a> on Friday. The longtime minor leaguer didn\u2019t get into the first game against the Reds, but started both matchups of Saturday\u2019s twin bill. Torres recorded three hits across the two games.<\/p>\n

Mautz has delivered a sub-3.00 ERA across nine starts at Triple-A this season. He\u2019s striking out more than a batter per inning, but his 13.5% walk rate is a career-worst mark. The 24-year-old is not among the upper tier of prospects in the St. Louis system, but he\u2019s generally among the top 20 in the organization. FanGraphs<\/a>\u2018 James Fegan ranked Mautz at No. 17 heading into the season, while MLB Pipeline<\/a> had him at 20th.<\/p>\n

The Cardinals selected Mautz in the second round of the 2022 draft out of the University of San Diego. The lefty posted decent results in his first pro season, recording a sub-4.00 ERA at Single-A. He took a step back in High-A the following year, with a 5.18 ERA to go with a 4.86 FIP. Mautz came through with a breakout season in 2025. He cruised to a 2.98 ERA with a career-best 28.6% strikeout rate in 25 starts at Double-A. Mautz was named the organization\u2019s minor league pitcher of the year last season.<\/p>\n

This could be a brief stint for Mautz, as the Cardinals don\u2019t have a clear hole in the rotation. The group has remained healthy and generally provided decent results. Veterans Dustin May<\/a>, Matthew Liberatore<\/a>, and Andre Pallante<\/a> haven\u2019t excelled on a per-inning basis, but they\u2019re offering length each time they take the ball. Michael McGreevy<\/a> is off to a strong start. Kyle Leahy<\/a>\u2018s transition to the rotation has gone reasonably well.<\/p>\n
